Recent Extensions of the ZKCM Library for Parallel and Accurate MPS Simulation of Quantum Circuits

A C++ library ZKCM and its extension library ZKCM_QC have been developed since 2011 for multiple-precision matrix computation and accurate matrix-product-state (MPS) quantum circuit simulation, respectively. In this report, a recent progress in the extensions of these libraries is described, which are mainly for parallel processing with the OpenMP and CUDA frameworks.
