论文摘要
量子模拟是证明量子计算能力的中央学科之一。近年来，量子超通道的理论框架已被广泛开发并作为量子通道的扩展。在这项工作中，我们研究了超通道的量子电路模拟任务。我们将基于凸的分解为极端超级通道的总和开发出量子超通道模拟算法，从而可以降低电路成本。我们通过高精度对量子超级通道的数值模拟来证明算法，使其适用于当前的实验平台。
Quantum simulation is one of the central discipline to demonstrate the power of quantum computing. In recent years, the theoretical framework of quantum superchannels has been developed and applied widely as the extension of quantum channels. In this work, we study the quantum circuit simulation task of superchannels. We develop a quantum superchannel simulation algorithm based on the convex decomposition into sum of extreme superchannels, which can reduce the circuit cost. We demonstrate the algorithm by numerical simulation of qubit superchannels with high accuracy, making it applicable to current experimental platforms.
