Abstract:

With the rapid development of quantum computing technology, quantum computing simulators in the Noisy Intermediate-Scale Quantum(NISQ) era have played a key role in promoting research on quantum algorithms. However, when processing large-scale quantum systems, quantum computing simulators face significant challenges in memory and computational resources. To break through this bottleneck, this study introduces Compute Express Link(CXL) technology to expand the scale of qubit count supported by quantum computing simulators. Through in-depth analysis of key technologies in quantum computing simulators and leveraging the advantages of CXL memory pooling technology, this study designs and implements a CXL memory-pool quantum computing simulator. The experimental results show that the quantum computing simulator based on CXL memory pool can effectively improve the bit scale of quantum simulation computing.
