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…

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…
