On-chip rare-earth ion quantum technologies

Institution: 
Caltech

Quantum interconnects that create entanglement between diverse quantum systems can enable integrated and highly scalable quantum technologies. Some components that will underpin such quantum interconnects include photonic quantum memories and quantum microwave-to-optical transducers. Rare-earth ions in solid state hosts are an appealing platform to pursue the realization of high performance quantum interconnects because of their proven track record in storage and generation of entangled photons, and their ability to convert between the microwave and optical domains. In this talk I will present some of the recent work from the Faraon Group at Caltech toward realizing an on-chip rare-earth platform that dramatically strengthens the ions’ interactions with optical fields, and integrates with planar microwave technology. The platform opens up opportunities for miniaturized quantum memories, single rare-earth ion spin qubits, and microwave-to-optical transduction on chip.
