Photonic quantum simulations of coupled -symmetric Hamiltonians
Nicola Maraviglia, Patrick Yard, Ross Wakefield +9
Parity-time () symmetric Hamiltonians are generally non-Hermitian and give rise to exotic behaviour in quantum systems at exceptional points, where eigenvectors coalesce. The r…
Entanglement generation using a controlled-phase gate for time-bin qubits
Hsin-Pin Lo, Takuya Ikuta, Nobuyuki Matsuda +2
Quantum logic gates are important for quantum computations and quantum information processing in numerous physical systems. While time-bin qubits are suited for quantum communicati…
Quantum process tomography of a controlled-phase gate for time-bin qubits
Hsin-Pin Lo, Takuya Ikuta, Nobuyuki Matsuda +3
Time-bin qubits, where information is encoded in a single photon at different times, have been widely used in optical fiber and waveguide based quantum communications. With the rec…
Generation of entangled photons using an arrayed waveguide grating
Nobuyuki Matsuda, Hidetaka Nishi, Peter Karkus +5
We propose an on-chip source of entangled photon pairs that uses an arrayed-waveguide grating (AWG) with multiple nonlinear input waveguides as correlated photon pair sources. The…
Deterministic reshaping of single-photon spectra using cross-phase modulation
Nobuyuki Matsuda
The frequency conversion of light has proved to be a crucial technology for communication, spectroscopy, imaging, and signal processing. In the quantum regime, it also offers great…
Slow light enhanced correlated photon pair generation in photonic-crystal coupled-resonator optical waveguides
Nobuyuki Matsuda, Hiroki Takesue, Kaoru Shimizu +3
We demonstrate the generation of quantum-correlated photon pairs from a Si photonic-crystal coupled-resonator optical waveguide. A slow-light supermode realized by the collective r…
