Entanglement and Transfer of Quantum Information

Towards an integrated photonic quantum information platform in diamond

Author: Dr Andrew Greentree (University of Melbourne)

Abstract

We present concepts relating to efforts to create an integrated platform for quantum information processing based on the properties of NV diamond. NV diamond is ideally suited for the production of single photons and entangled photons and for investigating the interconversion of flying and stationary qubits. Furthermore the diamond matrix can be used to generate waveguides for the generated light to propogate through. With the ability to fabricate single crystal diamond into complicated photonic structures, the possibility arises to generate optical circuitry to perform a range of tasks, including non-deterministic quantum logic elements.

We will present an overview of the theoretical efforts of the device modelling group, and then discuss plans for fabricating diamond waveguides, transform limited single photon sources in diamond using the NV Centre and photon discriminator using NV diamond.
