基于双威TaihuLight的量子超级电路仿真
Quantum Supremacy Circuit Simulation on Sunway TaihuLight
摘要：
随着工业界和学术界的快速进步，数十个量子比特甚至更大尺寸的量子计算机正在实现。然而，现有量子计算机的保真度通常会随着电路深度的增加而急剧下降。因此，一个理想的量子线路模拟器在经典计算机上，特别是在高性能计算机上，需要基准测试和验证。我们设计了一个通用随机量子线路的大规模模拟器，通常被称为“量子霸权电路”，并在神威太湖之光上实现。该模拟器可以完成以下两个任务：1）计算一个完整的输出状态向量; 2）计算一个或几个振幅。我们的目标是49量子位电路的模拟。对于任务1），我们成功地模拟了深度为39的电路，对于任务2），我们达到了55的深度水平。据我们所知，这两个模拟结果都达到了49量子比特量子霸权电路的最大深度。
英文摘要：
With the rapid progress made by industry and academia, quantum computers with dozens of qubits or even larger size are being realized. However, the fidelity of existing quantum computers often sharply decreases as the circuit depth increases. Thus, an ideal quantum circuit simulator on classical computers, especially on high-performance computers, is needed for benchmarking and validation. We design a large-scale simulator of universal random quantum circuits, often called 'quantum supremacy circuits', and implement it on Sunway TaihuLight. The simulator can be used to accomplish the following two tasks: 1) Computing a complete output state-vector; 2) Calculating one or a few amplitudes. We target the simulation of 49-qubit circuits. For task 1), we successfully simulate such a circuit of depth 39, and for task 2) we reach the 55-depth level. To the best of our knowledge, both of the simulation results reach the largest depth for 49-qubit quantum supremacy circuits.
