Quantum-Enhanced Sensing

Presented by Alberto Marino is an Associate Professor at the University of Oklahoma. His research focuses on experimental quantum optics, with particular emphasis on its applications to quantum information science and quantum metrology. Before arriving to the University of Oklahoma, he held a postdoctoral position and then an Assistant Research Scientist position at the Joint Quantum Institute (NIST/ University of Maryland). He obtained an M.S. and a Ph.D. in optics from the Institute of Optics at the University of Rochester.

There is a significant effort to take advantage of quantum resources, such as entanglement and superposition, to enhance measurements and devices in a way not possible with classical resources. This has led to the development of the emerging area of quantum technologies. Quantum optics will play a significant role in this so-called "Second Quantum Revolution" due to the precise control and characterization that can be achieved with light. In this talk I will describe our work on the interface between quantum states of light, known as twin beams, and plasmonic sensors. I will start by giving an overview of the properties of quantum states of light that make it possible to obtain a quantum enhancement of optical based sensors. I will then present our recent study of the interface between quantum states of light, known as twin beams, and localized surface plasmons. Finally, I will present results on the use of plasmonic structures consisting of an array of nanoholes as sensors and show that a quantum-based sensitivity enhancement is possible through the use of quantum states of light.
