Quantum state tomography through multi-frequency Josephson effect
Xian-Peng Zhang, Ting-Rui Hu, Zhen-Biao Yang +2
Macroscopic quantum effects emerge when the coherent behavior of countless microscopic quantum states manifests collectively at a visible scale, as exemplified by the supercurrent…
Experimental demonstration of entanglement sudden death induced by natural dissipation
Yan Wang, Hao-Long Zhang, Jia-Hao Lü +5
Any quantum system inevitably interacts with its natural environment, which can be modeled as a Markovian reservoir consisting of a continuum of electromagnetic field modes. The qu…
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…
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…
