PhD Studentship: RF and Photonic Engineering for Scaling Spin-based Quantum Information Platforms

University of Bristol - Electrical Engineering

Qualification Type: PhD
Location: Bristol
Funding for: UK Students, EU Students
Funding amount: £15,609
Hours: Full Time
Placed On: 4th June 2021
Closes: 4th September 2021

The project:

Solid state emitters are a critical component of future integrated quantum systems, in particular, for realizing efficient single photon sources and quantum memories. On the other hand, it is unclear how these bottom-up solid state systems can be scaled and interfaced from the O(1) emitter in a cavity that is routinely achieved in laboratories worldwide to say O(10) spectrally identical solid-state emitters in cavities interconnected by waveguides on a chip. In this project, we will address this issue of scaling bottom-up quantum systems by demonstrating a quantum optoelectronics platform in nitrogen vacancy centres in nanodiamonds.

On the RF engineering front, the candidate will design and characterize RF ASICs fabricated through Europractice for cryogenic spin control and manipulation, with an emphasis on low power and low crosstalk. In addition, the candidate will also get to work on techniques to interface these RF ASICs with photonic foundry chips in a flip-chip process that can successfully operate at low temperatures. During their PhD work, the candidate will pick up a diverse set of skills ranging from finite element simulation (using COMSOL and Lumerical FDTD), high frequency RF design and characterization, cryogenic device testing and nanofabrication methods for flip chip integration.
