报告题目/Title:

What more can “Quantum” Sensing offer?

讲座摘要/Abstract:

Quantum information science and technology signify the second quantum revolution. Quantum sensing exploits quantumness to enhance existing metrological techniques and to enable novel measurement schemes. The field of quantum sensing has been pushing the limits of sensitivity, resolution and precision of conventional metrology. An example is the detection of nuclear magnetic resonance of single atoms. The emerging trend in quantum sensing research is to develop novel schemes that have no classical counterparts, by exploiting the quantum nature of sensors as well as that of targets. For example, using the equivalence between the coherence of a quantum object in an environment and the environment’s partition function in the complex plane, it is possible to measure thermodynamic properties of a system with complex parameters. This capability led to the first observation of Lee-Yang zeros. Also, arbitrary types and orders of correlations in a quantum system may be extracted via a quantum sensor, which greatly enlarge the set of measurable correlations of classical nonlinear spectroscopy. The quantum nonlinear spectroscopy offers new approaches to studying quantum many-body physics and to classical-noise-free detection of quantum objects. We will discuss new opportunities in quantumness-enabled sensing.
