Quantum Optics as an Enabler for Quantum Technologies

Quantum optics has played a central role in the development of quantum mechanics over the last few decades, as it has proven to be a perfect test bed for unique quantum features such as entanglement and superposition. There is now a significant effort to take advantage of these quantum resources to enhance 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 continue to 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 present some of the work that my group has done to address some of the challenges to make quantum enhanced devices a reality, such as the control of quantum states of light and their interface with other systems.  I will present experiments on the generation and control of quantum states of light, known as twin beams, with a four-wave mixing process in atomic rubidium vapor.  I will then show how we have used these twin beams to implement a quantum enhanced plasmonic sensor.  Finally, I will give an overview of the future direction of this work.
