Rare-Earth Integration Program

Critical operations in quantum computing and communications require quantum information to be transferred between light fields and material quantum systems. To enable these operations this program is developing a series of optical solid-state interface devices, utilizing rare-earth optical centres in crystals. The emphasis of the program is the development of the hardware required to enable a long range quantum communication network. The building blocks of this hardware include quantum memories, non-classical light sources and small-scale quantum processors. A key outcome will be the integration of the rare-earth systems with detector and frequency conversion technology being developed in the Centre to demonstrate a quantum repeater. The Rare-Earth Integration Program is led by A.Prof Matthew Sellars based at the Australian National University in Canberra.
