报告摘要：

Quantum sensing explores protocols using certain quantum resources, such as entanglement, quantum squeezing and quantum criticality, to achieve a highly sensitive measurementof physical quantities. 안전 바카라 conventional schemes generally use a unitary rotation to encode 안전 바카라 quantityof interest into 안전 바카라 sensor’s state. However, such a unitary encoding scheme totally breaks down when one measures 안전 바카라 spectral density of a quantum reservoir. To solve 안전 바카라 above problem, we propose a nonunitary-encoding scheme to realize 안전 바카라non-Markoviansensing of a quantum reservoir. Although 안전 바카라 nonunitary dynamics shall result in 안전 바카라 deteriorationof quantum coherence, wesurprisingly find a mechanism, which is due to 안전 바카라 formation of a sensor-reservoir bound state, to make 안전 바카라 encoding time as a resource to improve 안전 바카라 sensing precision. Enriching 안전 바카라 family of quantum sensing, our scheme gives an efficient way tomeasure 안전 바카라 quantum reservoir and might supply an insightful support to decoherence control.
