Telecom-Integrated Photonic Memory Operating Near the Mechanical Ground State
Jindao Tang, Bo Jing, Liping Zeng +11
Scalable quantum networks require quantum memories that are chip-integrated, telecom-band compatible, and capable of flexible retrieval. Nanofabricated mechanical resonators meet t…
Dynamical Tipping in a Quantum Limit Cycle
Ya-Xin Xiang, Zhengyang Bai, Yu-Qiang Ma
Nonequilibrium systems maintain spatiotemporal order through energy dissipation and entropy production. Here, we demonstrate this principle by engineering a quantum limit cycle tha…
Enhanced quantum metrology by criticality-assisted noncommutative preparation
Ningxin Kong, Matteo G. A. Paris, Qiongyi He
Quantum criticality is a resource for quantum-enhanced metrology, but existing schemes face intrinsic limitations. These arise because using criticality directly in the encoding dy…
Quantum metrology via mitigation of single-photon loss using an engineered nonlinear oscillator
Tian-Le Yang, Wen Ning, Zhen-Biao Yang +1
The fragility of quantum metrological advantages under loss remains a major barrier to practical quantum sensing. For a two-photon-driven (TPD) Kerr resonator (TPD-Kerr model) subj…
Robust and optimal control of open quantum systems
Zi-Jie Chen, Hongwei Huang, Lida Sun +9
Recent advancements in quantum technologies have highlighted the importance of mitigating system imperfections, including parameter uncertainties and decoherence effects, to improv…
Quantum-enhanced estimation of signal field amplitudes with critical squeezed states of photonic modes
Ken Chen, Jia-Hao Lv, Wen Ning +2
Critical phenomena of quantum systems offer a promising strategy to improve measurement precision. So far, many criticality-enhanced quantum metrological schemes have been proposed…
