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…
Geometric measures of quantum nonlocality: characterization, quantification, and comparison by distances and operations
Gennaro Zanfardino, Wojciech Roga, Gianluigi Tartaglione +2
We introduce a geometric framework for studying Bell nonlocality in Hilbert space, where, for a given quantum state, nonlocality is quantified by the distance between the state and…
Quantum state estimation of multi-partite single photon path entanglement via local measurements
Hikaru Shimizu, Joe Yoshimoto, Kazufumi Tanji +5
Multipartite entanglement plays a critical role in various applications of quantum internet. In these applications, the entanglement is usually shared by the distant parties. Exper…
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…
