Non-Equilibrium Criticality-Enhanced Quantum Sensing with Superconducting Qubits
Hao Li, Yaoling Yang, Yun-Hao Shi +24
Exploiting quantum features allows for estimating external parameters with precisions well beyond the capacity of classical sensors, a phenomenon known as quantum-enhanced precisio…
A multinode quantum network over a metropolitan area
Jian-Long Liu, Xi-Yu Luo, Yong Yu +17
Towards realizing the future quantum internet, a pivotal milestone entails the transition from two-node proof-of-principle experiments conducted in laboratories to comprehensive, m…
Zeno Regime of Collective Emission: Non-Markovianity beyond Retardation
Yu-Xiang Zhang
To build up a collective emission, the atoms in an ensemble must coordinate their behavior by exchanging virtual photons. We study this non-Markovian process in a subwavelength ato…
Experimental investigation of entropic uncertainty relations and coherence uncertainty relations
Zhi-Yong Ding, Huan Yang, Dong Wang +3
Uncertainty relation usually is one of the most important features in quantum mechanics, and is the backbone of quantum theory, which distinguishes from the rule in classical count…
Cooling Flexural Modes of a Mechanical Oscillator by Magnetic Trapped Bose-Einstein Condensate Atoms
Donghong Xu, Fei Xue
We theoretically study cooling of flexural modes of a mechanical oscillator by Bose-Einstein Condensate (BEC) atoms (Rb87) trapped in a magnetic trap. The mechanical oscillator wit…
16-QAM Quantum Receiver with Hybrid Structure Outperforming the Standard Quantum Limit
Yuan Zuo, Ke Li, Bing Zhu
We present a quantum receiver for 16-QAM signals discrimination with hybrid structure containing a homodyne receiver and a displacement receiver, which can outperform the SQL, and…
