Simplification of tensor updates toward performance-complexity balanced quantum computer simulation

Koichi Yanagisawa, Tsuyoshi Okubo, Shota Koshikawa +3

Matrix Product States (MPS) provide a powerful framework for simulating quantum circuits. In practical simulations, tensor updates are typically performed in the canonical form (CF…

Efficient Bit Labeling in Factorization Machines with Annealing for Traveling Salesman Problem

Shota Koshikawa, Aruto Hosaka, Tsuyoshi Yoshida

To efficiently find an optimum parameter combination in a large-scale problem, it is a key to convert the parameters into available variables in actual machines. Specifically, quad…

Preconditioning for a Variational Quantum Linear Solver

Aruto Hosaka, Koichi Yanagisawa, Shota Koshikawa +3

We apply preconditioning, which is widely used in classical solvers for linear systems Ax=b, to the variational quantum linear solver. By utilizing incomplete L…
