Title: Distributed quantum sensing in a CV network
Abstract:
Quantum noise associated with quantum states of light and matter ultimately limits the precision by which measurements can be carried out. However, by carefully designing the coherence of this quantum noise to exhibit properties such as entanglement and squeezing, it is possible to measure various physical parameters with significantly improved sensitivity compared to classical sensing schemes. I will discuss recent work on demonstrating a continuous variable (CV) sensing network that exploit quantum correlations between probes for phase sensing with a precision beyond what is attainable with separable probes.
