Analogue black-white hole solitons in travelling wave parametric amplifiers with superconducting nonlinear asymmetric inductive elements
Haruna Katayama, Noriyuki Hatakenaka, Toshiyuki Fujii +1
We show that existing travelling wave parametric amplifier (TWPA) setups, using superconducting nonlinear asymmetric inductive elements (SNAILs), admit soliton solutions that act a…

Theoretical Studies on Quantum Walks with a Time-varying Coin
Haruna Katayama, Noriyuki Hatakenaka, Toshiyuki Fujii
Quantum walks can reconstruct quantum algorithms for quantum computation, where the precise controls of quantum state transfers between arbitrary distant sites are required. Here,…
