Quantum conjugate gradient method using the positive-side quantum eigenvalue transformation
Kiichiro Toyoizumi, Kaito Wada, Naoki Yamamoto +1
Quantum algorithms are still challenging to solve linear systems of equations on real devices. This challenge arises from the need for deep circuits and numerous ancilla qubits. We…
Hamiltonian simulation using quantum singular value transformation: complexity analysis and application to the linearized Vlasov-Poisson equation
Kiichiro Toyoizumi, Naoki Yamamoto, Kazuo Hoshino
Quantum computing can be used to speed up the simulation time (more precisely, the number of queries of the algorithm) for physical systems; one such promising approach is the Hami…
Perturbation theory with quantum signal processing
Kosuke Mitarai, Kiichiro Toyoizumi, Wataru Mizukami
Perturbation theory is an important technique for reducing computational cost and providing physical insights in simulating quantum systems with classical computers. Here, we provi…
