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…
Four-dimensional entanglement distribution over 100 km
Takuya Ikuta, Hiroki Takesue
High-dimensional quantum entanglement can enrich the functionality of quantum information processing. For example, it can enhance the channel capacity for linear optic superdense c…
Implementation of quantum state tomography for time-bin qudits
Takuya Ikuta, Hiroki Takesue
Quantum state tomography (QST) is an essential tool for characterizing an unknown quantum state. Recently, QST has been performed for entangled qudits based on orbital angular mome…
