Generation of a time-bin Greenberger--Horne--Zeilinger state with an optical switch
Hsin-Pin Lo, Takuya Ikuta, Koji Azuma +3
Multipartite entanglement is a critical resource in quantum information processing that exhibits much richer phenomenon and stronger correlations than in bipartite systems. This ad…
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),…
Precise tuning of single-photon frequency using optical single sideband modulator
Hsin-Pin Lo, Hiroki Takesue
Frequency translation of single photons while preserving their quantum characteristics is an important technology for flexible networking of photonic quantum communication systems.…
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…
Experimental investigation of performance differences between Coherent Ising Machines and a quantum annealer
Ryan Hamerly, Takahiro Inagaki, Peter L. McMahon +20
Physical annealing systems provide heuristic approaches to solving NP-hard Ising optimization problems. Here, we study the performance of two types of annealing machines--a commerc…
