Toward fault-tolerant quantum computation exploiting quantum spatial distribution and gauge symmetry

Ryo Asaka

We explore how the integrated use of quantum spatial distribution (QSD), or more specifically, a superposition of both spin and position states of particles, and gauge symmetry (GS…

Quantum error correction via multi-particle discrete-time quantum walk

Ryo Asaka, Ryusei Minamikawa

We propose a scheme of quantum error correction that employs a multi-particle quantum walk defined on nested squares, each hosting a single particle. In this model, each particle m…

Perfect transmission and parallel composition for quantum walks on graphs with two leads

Allan John Gerrard, Ryo Asaka, Kazumitsu Sakai

We study scattering for continuous-time quantum walks on finite graphs with two attached leads. We derive explicit formulae for the two-terminal scattering matrix in terms of chara…

Search for proton decay via $p \to e^{+} I ¨ ^{0} I ¨ ^{0}$ and $p \to I^¼^{+} I ¨ ^{0} I ¨ ^{0}$ in 0.401 megaton-years exposure of Super-Kamiokande I-V

Kamiokande Collaboration, K. Abe, S. Abe +310

We searched for proton decay via $p \to e^{+} I ¨ ^{0} I ¨ ^{0}$ and $p \to I^¼^{+} I ¨ ^{0} I ¨ ^{0}$ in 0.401 megaton-years of data collected in all pure water detector phases of Super-Kamiok…
