• Abstract: Quantum circuit simulators have a long tradition of exploiting massive hardware parallelism. Most of the times, parallelism has been supported by special purpose libraries tailored specifically for the quantum circuits. Quantum circuit simulators are integral part of quantum software stacks, which are mostly written in Python. Our focus has been on ease of use, implementation and maintainability within the Python ecosystem. We report the performance gains we obtained by using CuPy, a general purpose library (linear algebra) developed specifically for CUDA-based GPUs, to simulate quantum circuits. For supremacy circuits the speedup is around 2x, and for quantum multipliers almost 22x compared to state-of-the-art C++-based simulators.

  This paper presents techniques for theoretically and practically efficient and scalable quantum circuit simulation. Our approach partitions a quantum circuit into a hierarchy of subcircuits and simulates subcircuits on multi-node GPU. To minimize communication costs, we formulate an Linear Program that rewards simulation of "nearby" gates on "nearby" To maximize throughput, we use a dynamic programming algorithm to compute the subcircuit simulated by each kernel at a GPU.
