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,…
A path integral approach to Bayesian inference in Markov processes
Toshiyuki Fujii, Noriyuki Hatakenaka
We formulate Bayesian updates in Markov processes by means of path integral techniques and derive the imaginary-time Schrödinger equation with likelihood to direct the inference in…
Multipole surface plasmons in metallic nanohole arrays
Munehiro Nishida, Noriyuki Hatakenaka, Yutaka Kadoya
The quasi-bound electromagnetic modes for the arrays of nanoholes perforated in thin gold film are analyzed both numerically by the rigorous coupled wave analysis (RCWA) method and…
Quantum Knitting Computer
Toshiyuki Fujii, Shigemasa Matsuo, Noriyuki Hatakenaka
We propose a fluxon-controlled quantum computer incorporated with three-qubit quantum error correction using special gate operations, i.e., joint-phase and SWAP gate operations, in…
Fluxon-based generation of graph states in Josephson qubits
Toshiyuki Fujii, Masaru Fukunaga, Noriyuki Hatakenaka
Graph states are a special kind of multiparticle entangled state with great potential for applications in quantum information technologies, especially in measurement-based quantum…
