Enhanced Microwave Sensing with Dissipative Continuous Time Crystals
Yunlong Xue, Zhengyang Bai, Yu-Qiang Ma
A dissipative time crystal is an emergent phase in driven-dissipative quantum many-body systems, characterized by sustained oscillations that break time-translation symmetry sponta…
Arbitrary Instantaneous Bandwidth Microwave Receiver via Scalable Rydberg Vapor Cell Array with Stark Comb
Yuechun Jiao, Yuwen Yin, Yunhui He +7
Rydberg atoms have great potential for microwave (MW) measurements due to their high sensitivity, broad carrier bandwidth, and traceability. However, the narrow instantaneous bandw…
Switching Dynamics of Metastable Open Quantum Systems
Ya-Xin Xiang, Weibin Li, Zhengyang Bai +1
Classical metastability manifests as noise-driven switching between disjoint basins of attraction and slowing down of relaxation, quantum systems like qubits and Rydberg atoms exhi…
Thermal resonance-enhanced transparency in room temperature Rydberg gases
Jinlian Hu, Yuechun Jiao, Yuwen Yin +6
We report the enhanced optical transmission in the coherent, off-resonant excitation of Rydberg atom gases at room temperature via a two-photon process. Here thermal resonance-enha…
Single photonic qutrit in a collective Rydberg polariton
Yuechun Jiao, Oliver D. W. Hughes, Max Z. Festenstein +5
We report on the coherent creation, control and read-out of a single photonic qutrit in a Rydberg ensemble. In each measurement, an optical photon is stored as a Rydberg polariton…
Many-body nonequilibrium dynamics in a self-induced Floquet system
Yuechun Jiao, Yu Zhang, Jingxu Bai +5
Floquet systems are periodically driven systems. In this framework, the system Hamiltonian and associated spectra of interest are modified, giving rise to new quantum phases of mat…
