OSA Student Chapter Meeting

SPEAKER: Dr. Chris O'Brien
TITLE: Converting between optical photons and microwave qubits
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.
