Integrated photonic Galton board and its application for photon counting
Hezheng Qin, Risheng Cheng, Yiyu Zhou +1
The Galton board is a desktop probability machine traditionally used to visualize the principles of statistical physics with classical particles. Here, we demonstrate a photonic Ga…
Photonic link from single flux quantum circuits to room temperature
Mohan Shen, Jiacheng Xie, Yuntao Xu +5
Broadband, energy-efficient signal transfer between cryogenic and room-temperature environment has been a major bottleneck for superconducting quantum and classical logic circuits.…
Magnetic field-resilient quantum-limited parametric amplifier
Mingrui Xu, Risheng Cheng, Yufeng Wu +2
Superconducting parametric amplifiers are crucial components in microwave quantum circuits for enabling quantum-limited signal readout. The best-performing such amplifiers are ofte…
Unveiling photon statistics with a 100-pixel photon-number-resolving detector
Risheng Cheng, Yiyu Zhou, Sihao Wang +3
Single-photon detectors are ubiquitous in quantum information science and quantum sensing. They are key enabling technologies for numerous scientific discoveries and fundamental te…
Bidirectional electro-optic conversion reaching 1% efficiency with thin-film lithium niobate
Yuntao Xu, Ayed Al Sayem, Linran Fan +7
Superconducting cavity electro-optics (EO) presents a promising route to coherently convert microwave and optical photons and distribute quantum entanglement between superconductin…
Photorefraction-induced Bragg scattering in cryogenic lithium niobate ring resonators
Yuntao Xu, Ayed Al Sayem, Chang-Ling Zou +2
We report intracavity Bragg scattering induced by photorefractive (PR) effect in high-Q lithium niobate (LN) ring resonators at cryogenic temperatures. We show that, when a cavity…
