MAIN TALK
SPEAKER: Dr. Chris O'Brien
TITLE: Converting between optical photons and microwave qubits
ABSTRACT:
Superconducting circuits provide one avenue towards scalable quantum computing, however they operate at microwave frequencies which are not suitable for long range quantum communication. We consider the coupling of a traditional rare-earth doped crystal based optical quantum memory with a superconducting qubit through an intermediate microwave cavity. Thus a telecom wavelength photon can be absorbed by the memory, converted into a collective spin excitation, which couples to the cavity and is thus transferred into an excitation of a superconducting qubit. Conversely, the process can be reversed to read out a qubit into an optical photon.
