Abstract:

The past decade has seen tremendous progress towards the development of quantum networks, wherein quantum states are transmitted over long distances for applications in distributed quantum computing, quantum-enhanced metrology, and quantum key distribution. Quantum memories are expected to play a significant role in extending the reach and capabilities of such networks, but work in this area has typically been confined to single laboratory environments. In this talk, I will present a first step towards connecting quantum memories with a real-world, deployed fiber-optic network. Specifically, we demonstrate state transfer to a diamond defect center memory over a 50 km deployed fiber link in the Boston metropolitan area. I will then discuss pathways toward scalability through large-scale qubit characterization and novel architectures for both individual and multi-qubit systems. Together, these efforts represent a full-stack approach towards realizing scalable, memory-enabled quantum networks.
