Eugene Polzik: Quantum Optical Interface

polzikNiels Bohr Institute, Copenhagen

Quantum interfaces capable of transferring quantum states and generating entanglement between fields and matter play a crucial role in the development of quantum information science and technology. Optical fields are natural control and information carrier resources, whereas atomic and solid state devices are natural platforms for processing information and for measurement and sensing fields and forces. In the past few years quantum interfaces between atomic ensembles and optical photons have been extensively developed [1]. I will discuss recent progress with such interfaces as well as an ongoing work on interfacing light with electronic circuits using nanomechanical membranes.
