MURI 11) Multi-Functional Light-Matter Interfaces Based on Neutral Atoms and Solids
Abstract
The objective of this MURI program is the development of light-matter interfaces with the quantum memory and local quantum processing capabilities using atomic and solid-state systems. Quantum repeater architectures, which use quantum memory elements as nodes and light for transmission, require storage lifetimes that are large compared to the classical communication time between nodes. Storage lifetime requirements are increased further by the actual communication process, where multiple successful entanglement distributions are necessary within the quantum memory lifetime for the formation of a single quantum bit. For communication over distances of 1,000 km, quantum memory lifetimes of many seconds are required. This team pursues a program aimed at development and implementation of such long-lived quantum memories that can be strongly coupled to light. A promising candidate for a platform to implement such nodes is a charged quantum dot embedded in a nanoresonator. The use of resonators can strongly enhance light-matter interactions and therefore efficiently transfer information between photons and stationary qubits, and realize photonic quantum gates. Team members also employ the hyperfine ground levels of ultra-cold atoms, and charged nitrogen-vacancy and silicon vacancy defect centers in diamond as memory qubits.
