Ultra-high-rate detection of entangled photon pairs
Toshimori Honjo, Shigeyuki Miyajima, Shigehito Miki +5
The high-rate detection of entangled photons is essential for advancing photonic quantum information processing. Although several experimental demonstrations have been reported, th…
Model-based framework for automated quantification of error sources in quantum state tomography
Junpei Oba, Hsin-Pin Lo, Yasuhiro Yamada +6
High-quality quantum state generation is essential for advanced quantum information processing, including quantum communication, quantum sensing, and quantum computing. In practice…
10-GHz-clock time-multiplexed non-degenerate optical parametric oscillator network with a variable planar lightwave circuit interferometer
Yuya Yonezu, Kensuke Inaba, Yasuhiro Yamada +4
A coherent XY machine (CXYM) is a physical spin simulator that can simulate the XY model by mapping XY spins onto the continuous phases of non-degenerate optical parametric oscilla…
Observing a Phase Transition in a Coherent Ising Machine
Hiroki Takesue, Yasuhiro Yamada, Kensuke Inaba +8
A coherent Ising machine (CIM) is known to deliver the low-energy states of the Ising model. Here, we investigate how well the CIM simulates the thermodynamic properties of a two-d…
High-performance, adiabatically nanotapered fibre-chip couplers in silicon at 2 microns wavelength
Dominic A. Sulway, Yuya Yonezu, Lawrence M. Rosenfeld +3
Fibre optic technology connects the world through the Internet, enables remote sensing, and connects disparate functional optical devices. Highly confined silicon photonics promise…
Scalable implementation of mutually unbiased bases for -dimensional quantum key distribution
Takuya Ikuta, Seiseki Akibue, Yuya Yonezu +3
A high-dimensional quantum key distribution (QKD) can improve error rate tolerance and the secret key rate. Many -dimensional QKDs have used two mutually unbiased bases (MUBs),…
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…
