Fast and accurate simulation of quantum computing by multi-precision MPS: recent development. The time-dependent matrix-product-state (TDMPS) simulation method has been known as one of fast simulation methods to study time-evolving quantum systems. Here, I report recent development of my open-source C++ library named ZKCM_QC designed for TDMPS simulations of quantum circuits with arbitrary floating-point precision. Simulation performance is reported for well-known quantum algorithms. In addition, it is numerically shown that a trustworthy simulation should be performed in multiprecision and should not involve truncations of nonzero Schmidt coefficients.
