Different from the static counterpart, dynamic circuits can not only implement a set of basic quantum operations like the Hardmard gate, CNOT gate, or qubit reset but also can implement measurement in the middle of a circuit, store the measurement results to classical bits, evaluate classical expressions on the fly, and determine what quantum operation to do next.\n\nThis capability has a variety of applications, for example quantum error correction, quantum simulation, and so on. We encourage you to explore what you can do with dynamic circuits in this challenge! Bonus point if you show improvement of your dynamic circuit implementation over its static counterpart - for example, use dynamic circuit feature to shorten the circuit depth, suppress error rate, and so on! After you create a dynamic circuit of your interest and are ready to run it on the hardware, bear in mind that the current quantum computers are noisy! In practical implementation, the operations in a dynamic circuit can be faulty, so it is important to quantify their fidelities and model the noise mechanism on their own or in the context of a circuit.\n\nIn the case of dynamic circuits, the types of error and how error propagates will be more complicated due to the hybrid quantum and classical nature of noise. We challenge you to characterize the noise in dynamic circuits. Fortunately, there is a suite of noise characterization and verification tools like tomography and randomized benchmarking, which are fairly well understood on static circuits, and extending them to dynamic circuits is an interesting research question to take on.\n\n# Challenge ideas\n\n* Find an application using dynamic circuits For example: prepare a large GHZ state, generate long-range entanglement, prepare a repetition code, do quantum phase estimation.\n\n* Demonstrate the improvement of implementation using the dynamic circuit feature. For example: use dynamic circuit feature to shorten circuit depth or suppress error rate in a real circuit execution.\n\n* Characterize noise and errors in dynamic circuits For example, study how error propagates in dynamic circuits: use a benchmark method to study the fidelities of individual operations and composite operations in dynamic circuits.\n\n* With deeper understanding of how noise affects dynamic circuits, could you think of ways to suppress noise?\n\n# Judging criteria\n\nDynamic circuits are a new Qiskit feature and a cutting edge capability in the quantum world. As such, we will value your implementation effort, but also your ability to show you understood the concept, its applications, and its power. You are encouraged to put effort into showing your end result: prepare a clear presentation, contextualize dynamic circuits, and put emphasis on comparing dynamic circuits against \"vanilla\" quantum circuits. Remember: the end goal here is to make you learn useful skills and concepts that will help you along your journey into quantum information technology!\n\n# Getting started resources\n\n* What are dynamic circuits? Find out from the IBM’s blog post [here](https://www.ibm.com/quantum/blog/quantum-dynamic-circuits).\n\n* Documentation on dynamic circuits [here](https://docs.quantum.ibm.com/build/classical-feedforward-and-control-flow)\n\n* For testing and debugging the quantum circuits locally, the [qiskit_aer](https://github.com/Qiskit/qiskit-aer) simulators can be useful\n\nFurther reading about dynamic circuits:\n\n - [Exploiting Dynamic Quantum Circuits in a Quantum Algorithm with Superconducting Qubits](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.127.100501)\n - [Efficient Long-Range Entanglement using Dynamics Circuits](https://arxiv.org/pdf/2308.13065.pdf)\n - [A randomized benchmarking suite for mid-circuit measurements](https://iopscience.iop.org/article/10.1088/1367-2630/ad0e19)"},{"id":648,"name":"Cap/Hartford/Quantinuum Challenge Track","slug":"cap-hartford-quantinuum-challenge-track","description":"# YQuantum Hackathon - State preparation for quantum computing Monte Carlo\nBy The Hartford and Capgemini, with Platform Sponsor Quantinuum\n\n# Introduction\n\nQuantum computing, with its extraordinary promise of computational speedups, stands poised to revolutionize various industries. Among these, the insurance sector is particularly ripe for transformation. Enter the technique known as **Quantum Computing Monte Carlo** (QCMC), a quantum counterpart to the classical “Monte Carlo” method. By harnessing the unique properties of quantum systems, QCMC holds the potential to drive significant improvements in insurance processes.\n\n# Monte Carlo for insurance\n\nBefore we investigate QCMC, let’s look at Monte Carlo simulations on classical computers. Monte Carlo methods involve **random sampling** and **deterministic computation**. Here’s a concise breakdown:\n\n1. **Random Sampling**: We generate random inputs (often following specific probability distributions) for a system’s parameters. These inputs represent different scenarios.\n2. **Deterministic Computation**: For each set of sampled inputs, we perform a deterministic computation. The result provides an estimate for the desired quantity.\n\nThe big challenge is the fact that to get a good aggregation, we need many iterations. Specifically, to achieve an aggregation with an error , we need ) iterations.\n\n## Applications in insurance\n\n**Monte Carlo methods** find a special place in the insurance industry. Here are some applications of Monte Carlo methods in the insurance industry:\n\n- **Risk Assessment:** Simulating scenarios helps insurers understand potential outcomes.\n- **Premium Calculations:** Monte Carlo aids in estimating insurance premiums.\n- **Reserve Estimation:** Insurers use it to estimate reserves for future claims.\n- **Stress Testing:** Assessing financial stability through extreme scenarios.\n\nDuring this hackathon, you will focus on reserve estimation.\n\n## Conditional Value-at-Risk\n\nConditional Value-at-Risk (CVaR), also known as Expected Shortfall (ES), is a risk measure that quantifies the expected loss of an investment portfolio over a specific time under extreme market conditions. Unlike Value-at-Risk (VaR) which only considers the maximum loss at a certain confidence level, CVaR considers the severity of the losses beyond the VaR threshold. This makes CVaR a more comprehensive measure of risk as it provides an estimate of the expected value of the extreme losses. In the context of insurance, CVaR can be used to assess the potential losses an insurer could face in extreme scenarios, thereby aiding in reserve estimation and stress testing. It’s particularly useful in the context of tail risk management, where the focus is on extreme events that have a small probability of occurrence but could lead to significant losses.\n\n# Quantum Computing Monte Carlo\n\nMonte Carlo methods are ubiquitous in insurance. Sometimes, however, it is not possible to run the Monte Carlo simulations as you would like, because they take too much computer power. Quantum Computing Monte Carlo promises a quadratic speed-up, as it is based on Grover’s algorithm. The result is that the accuracy no longer scales as , rather the QCMC scales as .\n\nThe result is algorithmic speed-up, which translates to:\n\n- Faster results with the same accuracy\n- Higher accuracy in the same calculation time\n- More complex models (fewer assumptions) with the same accuracy in the same calculation time\n\n## Amplitude Estimation\n\nQCMC is based on Amplitude Estimation^{[\\[1\\]](#footnote-1)}. In Amplitude Estimation, you use phase estimation and amplitude amplification to estimate the amplitude of a marked state. The trick is to encode a value of interest in the amplitude of the marked state. Previous work has done this for risk analysis^{[\\[2\\]](#footnote-2)} and option pricing^{[\\[3\\]](#footnote-3)}.\n\nFor more information about how to practically run a CVaR calculation, please refer to the excellent tutorial by IBM attached.\n\n[ Note by Francesco: I don't seem to find any IBM tutorial attached. Here's a qiskit link that refers to the topic - hopefully it was the one originally intended :D https://qiskit-community.github.io/qiskit-finance/tutorials/09_credit_risk_analysis.html#Conditional-Value-at-Risk ]\n\n\n\n## State Preparation\n\nThe question now is how to load the value of interest in the amplitude. There exist methods for this^{[\\[4\\]](#footnote-4)}, however, loading the state has such high overhead in terms of circuit depth, that this sub procedure might negate any computational advantage that QCMC has to offer^{[\\[5\\]](#footnote-5)}.\n\n# The challenge\n\nYour challenge is to create a toy example Quantum Computing Monte Carlo pipeline (e.g., using Qiskit/TKET) to estimate risk and subsequently estimate how much reserves the insurer should keep.\n\nIn that pipeline, focus on the state preparation method and try to come up with a method that fits the NISQ constraints, i.e., relatively many qubits, with relatively poor quality. I.e., use ancilla qubits to decrease the circuit depth. (hint: which gates can a quantum computer execute?)\n\nNow, can you estimate how your pipeline scales? In terms of circuit depth, circuit width, and accuracy.\n\n# Setup\n\n1. Clone the repository:\n ```\n git clone https://github.com/camilledevalk/yquantum-hartford-capgemini\n ```\n1. Navigate to the cloned repository:\n ```\n cd yquantum-hartford-capgemini\n ```\n\n1. Create a new conda environment from the `environment.yml` file:\n ```\n conda env create -f environment.yml -n yquantum\n ```\n\n1. Activate the new environment:\n ```\n conda activate yquantum\n ```\n\nNow, you're ready to run the project!\n\nIn `notebooks/problem-setting.ipynb`, the problem is expressed in code.\n\n# Quantum Hardware\n\nQuantinuum is the platform sponsor for this challenge.

In this phenomenon, a many-body quantum system is driven into one state of a degenerate ordered phase and given a sudden “drive kick” – technically known as a quench. This quench onsets a melting of the ordered phase, which then evolves under the influence of quantum mechanics. Organically, and surprisingly, the melted system “refreezes” in another instance of the set of degenerate phases. The process keeps repeating itself – naturally losing coherence.\n\nChallenge goals: In most hackathons, particularly in quantum ones, a big emphasis is given to application development.

This document serves as a comprehensive challenge guide, designed for quantum computing enthusiasts at all levels. From beginners to seasoned experts, we aim to enrich your understanding of sparse state-preparation and spur innovation in the field of quantum computing, specifically focusing on the nuanced domain of sparse state-preparation. Classiq’s platform, QMOD language, and SDK offer powerful abstractions for expediting the process of quantum algorithm design, prototyping, implementation, and testing. Your team will leverage these abstractions in order to develop a competitive solution within a 24 hour period.\n\nBackground: State Preparation\nState preparation underpins quantum computing, acting as the foundational step for a multitude of quantum algorithms across diverse fields such as quantum linear algebra, quantum chemical modeling, quantum search protocols, and quantum machine learning. It involves configuring a quantum state to represent a specific vector of probabilities or a predefined function. The efficiency of state preparation is a critical determinant in harnessing the true potential of quantum computational advantages, particularly in scenarios where classical computation becomes impractical due to exponential increases in resource requirements. Classiq’s SDK and QMOD language have built-in functions for quantum state preparation. However, it is not computationally efficient for sparse state preparation.\n\nThe Problem: Sparse State-Preparation\n\nSparse state-preparation, a specialized subset of state preparation, emphasizes the generation of quantum states characterized by a significant proportion of zero amplitudes. This feature is prevalent in numerous quantum computing applications, where the desired quantum state comprises a small number of non-zero amplitudes amidst a potentially vast set. By exploiting the inherent sparsity, sparse state-preparation algorithms aim to drastically reduce the quantum resources required, such as quantum gates and circuit complexity. This aspect is vital for the practical execution of complex quantum algorithms on near-term quantum hardware, which is constrained by limitations in qubit count, gate fidelity, and coherence times.\n\nChallenge Brief\n\nObjective: The challenge is designed to inspire participants to develop quantum circuits capable of efficiently preparing sparse quantum states. Entrants are tasked with creating circuits that load a quantum state with probabilities corresponding to a given sparse vector of probabilities, ensuring the presence of \n\n\nonly a constant number of non-zero probabilities. The key lies in achieving this with minimal resource utilization and maximal fidelity. \"An Efficient Algorithm for Sparse Quantum State Preparation\" by Niels Gleinig and Torsten Hoeﬂer provides a two-part algorithm for sparse state preparation. Participants should read, understand, and base their implementation off of the paper.\n\nGiven a list of indices and their respective probabilities, your team is tasked with creating a circuit such that it loads a state with amplitudes in the magnitudes of these probabilities. The circuit will not take phase amplitude into account, meaning that ai will always be a square root of a real number. \n\n$ |\\psi⟩_{n}=\\sum_{I}a_{I}|I⟩_{n} such that a_{I}^2=pi $.\n(notice that your team has the freedom to load the amplitude with an arbitrary phase).\n\nExample Scenario:\n- Input: A probabilities dictionary, such as:\nSparse_states = {‘00000001’: 0.25, ‘00010001’: 0.5, ‘11001000’: 0.25}\n\n- Output Goal: Efficiently load a quantum state reflecting these probabilities, such as:\n|⟩8=0.25|1⟩8+0.5|17⟩8+0.25|200⟩8\n\n- A sample output for the specified example:\n\n\n\n\nDetailed Considerations for Participants\n- Auxiliary Qubits: Their use is permitted, provided they do not remain entangled or in non-zero states post-operation.\n- Adaptability and Efficiency: Solutions should be versatile, considering the trade-offs between circuit depth, number of auxiliary qubits, gate count, and other circuit parameters.\n- Innovative Approach: Encourage exploration beyond conventional methodologies.\n\n\n\nComprehensive Submission Guidelines\nParticipants are required to submit:\n1. `.qmod` and `.qprog` files showcasing their quantum circuit design and implementation.\n2. Results demonstrating the execution of their circuit, saved as JSON.\n3. The Python code employed for model generation.\n4. An in-depth explanation detailing their approach and methodology. Create a README, outlining an abstract overview of your team's implementation. The README should outline the functional outline of all Quantum Functions used in your program, including their parameters/arguments and outputs.\n\nEvaluation Criteria\nSubmissions will be assessed based on:\n1.) Target Problem Solving: Correct sparse quantum state preparation for the following scenarios:\nFor 6 qubits: Probs = {‘000011’: 0.4, ‘111111’: 0.6}\nFor 10 qubits: Probs = {‘0000000101’: 0.33, ‘0000010001’: 0.33, ‘0001100010’: 0.34}\nFor 20 qubits: Probs = {‘00000000000000000101’: 0.6, ‘00000000000000010001’: 0.4}\n2.) Optimization Balance: Utilizing Pareto analysis to evaluate the balance between circuit depth and auxiliary qubit usage.\n3.) Originality and Creativity: Encouraging unique and innovative solutions.\n4.) Scalability and Versatility: The ability to efficiently manage different numbers of qubits and non-zero coefficients.\n\nGuidelines for Implementation\n- Foundational Understanding: Solidify your grasp of quantum state preparation fundamentals and the critical role of sparsity.\n- Resource Optimization: Prioritize minimizing quantum resources while maximizing performance and accuracy.\n- Circuit Design Exploration: Engage with various quantum circuit design and optimization strategies to discover the most efficient approach for sparse state preparation.\n- Rigorous Testing: Ensure thorough testing and validation of your circuits to confirm the accurate preparation of the desired sparse quantum states.\n\nKeep Note\n\nYou're tasked with creating quantum circuits to prepare specific states. You are permitted to utilize auxiliary qubits. Nonetheless, it's essential to ensure that at the circuit's conclusion, there are no residual non-zero or entangled qubits apart from the designated loaded state. You will be provided a template notebook with some already defined functions. You are tasked with implementing the remaining logic based on the two-part algorithm described in the provided research paper, \"An Efficient Algorithm for Sparse Quantum State Preparation\".\n\nThere's a spectrum of potential solutions for this task. The efficiency of particular approaches might fluctuate based on problem dimensions. Furthermore, one must navigate trade-offs between multiple circuit parameters: the circuit's depth, the count of auxiliary qubits, gate numbers, and so on. Take note of the following example comparing prepare_sparse_states and the built-in prepare_state. Notice that a proper implementation of prepare_sparse_states creates a circuit with depth of 8. In comparison the built-in prepare_state function creates the same quantum state with a circuit depth of 63.\n\n\n\n@qfunc\ndef main(psi: Output[QArray[QBit]]):\n sparse_state_dic ={'000':0.25, '001':0.5, '111':0.25}\n prepare_sparse_state(dictionary=sparse_state_dic,out=psi)\n\n\n\n\n\n@qfunc\ndef main(psi: Output[QArray[QBit]]):\n sparse_state_dic ={'000':0.25, '001':0.5, '111':0.25}\n sparse_state_array = convert_dic2array(sparse_state_dic)\n prepare_state(sparse_state_array,0.001,psi)\n\nBest of Luck to All Participants!\n\nParticipating in this challenge presents a unique opportunity to contribute to the advancement of quantum computing technology and to explore new frontiers in the quantum domain.

If multiple teams produce significant results, the prizes will be divided among the winners. The prizes will be distributed through DoraHacks' DAO Bounties platform.\n\n# Motivation\nQuantum computers promise diverse applications with fault-tolerant architectures. Near-term quantum computers are comprised of different physical entities, such as superconducting qubits, propagating photons, trapped ions and tweezer-based neutral atoms. \n\nRandomness lies in the cornerstone of quantum mechanics, especially in the dispute of reality and non-locality [1]. After decades of experimental progress [2], loophole-free Bell inequality was demonstrated by several groups using photons [3, 4] and superconducting qubits [5]. As a result, device-independent certified quantum random number generator [6] and randomness expansion [7, 8] are cutting-edge and realistic applications. Besides, one of the potential applications of NISQ quantum advantages (e.g. random circuits sampling) is also certified randomness [9, 10].\n\nCurrent cloud-based quantum computers service is ready for producing quantum random numbers for cryptography. However, due to the notorious decoherence processes, the raw entanglement between isolated qubits is deteriorated without any digital error-mitigation technique (like readout correction). Thus, we are curious about the randomness degradation. More specifically, is it possible to distinguish the given random numbers are produced from a specific quantum computer?\n\nTake the output from a quantum random number generator as training data, the data is produced by different IBMQ simulators (including noise). Find a way to create a model that classifies new random number output, and identifies which machine the random number is produced from. The quantum random number generator functions as described in https://github.com/dorahacksglobal/quantum-randomness-generator. Run experiments by yourself, and compare different models. Is this classification task possible? What are the possible ways to improve the model so that it's useful?\n\nMore generally, this problem is related to the topic of cross-platform comparison of quantum circuits [11, 12].\n\n# Training Data\nData file link [here](https://drive.google.com/file/d/1xXu_8GGO7QxnQhwX4H1yVFXwErNaYFHH/view?usp=sharing). \n\n# References\n[1] Einstein, Albert, Boris Podolsky, and Nathan Rosen. \"Can quantum-mechanical description of physical reality be considered complete?.\" Physical review 47.10 (1935): 777.
