Experimental zero-added-loss multiplexing Bell-pair source for long-haul quantum networks
Yoshiaki Tsujimoto, Daiki Ichii, Rikizo Ikuta +4
Boosting the communication rate of quantum networks is a central challenge in quantum information science. Recently, an efficient entanglement distribution scheme employing quasi-d…
Experimental entanglement swapping through single-photon nonlinearity
Yoshiaki Tsujimoto, Kentaro Wakui, Tadashi Kishimoto +5
In photonic quantum information processing, quantum operations using nonlinear photon-photon interactions are vital for implementing two-qubit gates and enabling faithful entanglem…
Evaluating a Multi-Color Entangled-Photon Source for a Bosonic Silicon Quantum Circuit
Koki Nagamachi, Hiroki Yamashita, Mikio Fujiwara +3
We evaluated a multi-color two-photon entangled state generated in silicon via spontaneous four-wave mixing (SFWM) as a potential source for bosonic integrated circuits. Spatially…
Programmable Quantum Linear Interference with Pulse Shaping of Quantum Light
Aruto Hosaka, Masaya Tomita, Yoshiaki Tsujimoto +6
In this paper, we propose a novel method for interfering frequency-multiplexed photonic quantum states without the use of optical nonlinear effects, and experimentally demonstrate…
