Theoretical Studies on Quantum Walks with a Time-varying Coin
Haruna Katayama, Noriyuki Hatakenaka, Toshiyuki Fujii · Electronic Proceedings in Theoretical Computer Science · 2020
Quantum walks can reconstruct quantum algorithms for quantum computation, where the precise controls of quantum state transfers between arbitrary distant sites are required. Here, we investigate quantum walks using a periodically time-varying coin both numerically and analytically, in order to explore the controllability of quantum walks while preserving its random nature.
