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…
Rapid characterisation of linear-optical networks via PhaseLift
Daniel Suess, Nicola Maraviglia, Richard Kueng +6
Linear-optical circuits are elementary building blocks for classical and quantum information processing with light. In particular, due to its monolithic structure, integrated photo…
Evaluation of graphene optical nonlinearity with photon-pair generation in graphene-on-silicon waveguides
Yuya Yonezu, Rai Kou, Hidetaka Nishi +4
We evaluate the nonlinear coefficient of graphene-on-silicon waveguides through the coincidence measurement of photon-pairs generated via spontaneous four-wave mixing. We observed…
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…
