Experimental demonstration of plasmonic quantum walks in the one-dimensional gold-strip waveguide lattice structure
Shuichiro Inoue, Nihon University
Quantum walks (QWs) simulate quantum mechanical behaviours of particles, which exhibit time evolutions completely different from the classical random walks. QWs offer quantum physical simulations and the novel approach to build quantum computers. Currently on-chip photonic devices have been intensively developed and QWs have been implemented using photonic circuits based on silica waveguide platforms.
We have experimentally demonstrated QWs in
one-dimensional lattice structures based on the long-range surface plasmon
polariton (LR-SPP) waveguide platform. The LR-SPP waveguide allows a
single-polarization mode, and has relatively low optical losses. The
