Abstract
Section titled āAbstractāIn recent years there has been substantial progress in solid-state quantum information demonstrations based on diamond. This ranges from room-temperature multi-qubit quantum registers to spin-photon entanglement to loophole-free Bell tests. Most of these demonstrations are done with the nitrogen-vacancy (NV) center. Recently however the silicon-vacancy (SiV) center has shown a much better coupling to photons, owing to the suppression of spectral diffusion. Still more recently the germanium-vacancy (GeV) has shown much higher quantum efficiency the SiV. However there are tradeoffs. In this talk I will review the various options for quantum information devices in diamond. I will also discuss new options for the future, including designer color centers made possible by novel diamond growth techniques.
