Chip-to-chip hyperentanglement distribution and entanglement purification using silicon integrated photonics
Yonghe Yu, Mujtaba Zahidy, Siyan Zhou +4
Quantum repeaters are employed in quantum communication to overcome the long-distance transmission loss of quantum states. The quantum repeater is based on various key technologies…
Temporal Multiplexing of Heralded Photons Based on Thin Film Lithium Niobate Photonics
Cagin Ekici, Yonghe Yu, Jeremy C. Adcock +8
Heralded photons from a silicon source are temporally multiplexed utilizing thin film lithium niobate photonics. The time-multiplexed source, operating at a rate of R = 62.2 MHz, e…
High Resolution On-Chip Thin-Film Lithium Niobate Single-Photon Buffer
Cagin Ekici, Yonghe Yu, Jeremy C. Adcock +6
We experimentally demonstrate a room-temperature, voltage controlled, short-term quantum photonics memory on a lithium niobate chip. Our chip is capable of resolving 100 ps time st…
Observation of residual entanglement in chip-based entanglement purification
Yonghe Yu, Mujtaba Zahidy, Siyan Zhou +4
Entanglement purification is an essential component of quantum repeaters, as it can improve the fidelity of the distributed entangled states and mitigate the effects of the noisy c…
Experimental Demonstration of Underwater Decoy-state Quantum Key Distribution with All-optical Transmission
Yonghe Yu, Wendong Li, Yu Wei +8
We demonstrate the underwater quantum key distribution (UWQKD) over a 10.4-meter Jerlov type III seawater channel by building a complete UWQKD system with all-optical transmission…
Entanglement Purification by Integrated Silicon Photonics
Yonghe Yu, Siyan Zhou, Mujtaba Zahidy +4
We demonstrate the first on-chip deterministic entanglement purification based on silicon photonics. To evaluate the purification performance, we simulate the bit-flip and phase-fl…
Practical underwater quantum key distribution based on decoy-state BB84 protocol
Shanchuan Dong, Yonghe Yu, Shangshuai Zheng +4
Polarization encoding quantum key distribution has been proven to be a reliable method to build a secure communication system. It has already been used in inter-city fiber channel…
