A general formulation of time-optimal quantum control and optimality of singular protocols
Hiroaki Wakamura, Tatsuhiko Koike
We present a general theoretical framework for finding the time-optimal unitary evolution of the quantum systems when the Hamiltonian is subject to arbitrary constraints. Quantum b…

Noise suppression by quantum control before and after the noise
Hiroaki Wakamura, Ryûitirô Kawakubo, Tatsuhiko Koike
We discuss the possibility of protecting the state of a quantum system that goes through noise, by measurements/operations before and after the noise process. The aim is to seek fo…
