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…
Ground-state Pulsed Cavity Electro-optics for Microwave-to-optical Conversion
Wei Fu, Mingrui Xu, Xianwen Liu +9
In the development of quantum microwave-to-optical (MO) converters, excessive noise induced by the parametric optical drive remains a major challenge at milli-Kelvin temperatures.…
Epitaxial niobium nitride superconducting nanowire single-photon detectors
Risheng Cheng, John Wright, Huili G. Xing +2
Superconducting nanowires used in single-photon detectors have been realized on amorphous or poly-crystalline films. Here, we report the use of single-crystalline NbN thin films fo…
Cavity piezo-mechanics for superconducting-nanophotonic quantum interface
Xu Han, Wei Fu, Changchun Zhong +8
Hybrid quantum systems are essential for the realization of distributed quantum networks. In particular, piezo-mechanics operating at typical superconducting qubit frequencies feat…
Design of micron-long superconducting nanowire perfect absorber for efficient high speed single-photon detection
Risheng Cheng, Sihao Wang, Chang-Ling Zou +1
Despite very efficient superconducting nanowire single-photon detectors (SNSPDs) reported recently, combining their other performance advantages such as high speed and ultra-low ti…
