Theory of electron transport and electron-to-photon qubit conversion

Research Topic

The efficient use of acoustic field for quantum control requires theoretical tools to describe the processes of quantum information conversion from electron-spin qubits to photon-polarization qubits. These conversion processes offers a promising approach to the design of scalable quantum computers.


Goals

The main goal of the project is to describe theoretically the conversion from electron-spin qubits to photon-polarization qubits, and to make accurate simulations of an electron moving in a SAW-driven channel and then recombining with a hole to produce a photon. The results will be applied to analyse device structures investigated at UCAM as well as in other devices of relevance to the SAWtrain consortium. Once single electron transport in semiconductors is well understood, we will model the conversion of quantum information from electron-spin qubits to photon-polarization qubits. The requirements for preserving qubit coherence rather than just measuring the spin will then be investigated.

Scientific Background

I obtained a B.Sc. in Honours Physics at McGill University in 2013. This gave me a solid foundation in theoretical physics. I explored a more applied field during my masters when I joined the department of electrical and computer engineering at the University of Toronto. However, I felt the call within me to go back to theoretical physics. I am currently a Ph.D. candidate in the Quantum Information group at the University of Cambridge and part of the Marie Curie SAWtrain ITN.
