Detection of quantum signals free of classical noise via quantum correlation
Yang Shen, Ping Wang, Chun Tung Cheung +3
Extracting useful signals is key to both classical and quantum technologies. Conventional noise filtering methods rely on different patterns of signal and noise in frequency or tim…
Detection of arbitrary quantum correlations via synthesized quantum channels
Ze Wu, Ping Wang, Tianyun Wang +6
Quantum correlations are key information about the structures and dynamics of quantum many-body systems. There are many types of high-order quantum correlations with different time…
Quantum nonlinear spectroscopy of single nuclear spins
Jonas Meinel, Vadim Vorobyov, Ping Wang +7
Nonlinear spectroscopy is widely used for studying physical systems. Conventional nonlinear optical spectroscopy and magnetic resonance spectroscopy, which use classical probes suc…
Classical-noise-free sensing based on quantum correlation measurement
Ping Wang, Chong Chen, Renbao Liu
Quantum sensing, using quantum properties of sensors, can enhance resolution, precision, and sensitivity of imaging, spectroscopy, and detection. An intriguing question is: Can the…
Effects of local decoherence on quantum critical metrology
Chong Chen, Ping Wang, Ren-Bao Liu
The diverging responses to parameter variations of systems at quantum critical points motivate schemes of quantum metrology that feature sub-Heisenberg scaling of the sensitivity w…
Characterization of arbitrary-order correlations in quantum baths by weak measurement
Ping Wang, Chong Chen, Xinhua Peng +2
Correlations of fluctuations are the driving forces behind the dynamics and thermodynamics in quantum many-body systems. For qubits embedded in a quantum bath, the correlations in…
