Mikhail Lukin: Towards Quantum Networking with Atom-like Systems

"Special Seminar at the Walter Schottky Institute"

Abstract: We will discuss our progress towards realization of quantum repeaters for long-distance quantum communication using solid-state atom-like systems in nanophotonic devices.Specifically, we will describe experimental realization of memory-enhanced quantum communication, which utilizes a solid-state spin memory integrated in a nanophotonic diamond resonator to implement asynchronous Bell-state measurements. This enables a four-fold increase in the secret key rate of measurement device independent quantum key distribution over the loss-equivalent direct-transmission method while operating at megahertz clock rates. Recent progress including entanglement of dissimilar quantum emitters, realization of single photon sources, and multi-qubit quantum nodes will be discussed. Prospects for scaling up these techniques towards realization of quantum networks will be discussed
