PhD

We wish to recruit motivated students to join our group from September 2021. Applicants should have, or expect to obtain a 1st Class Honours degree in a relevant numerate discipline, for example Physics, Electrical and Electronic Engineering, or Materials Science.

These PhD projects (mostly experimental) offer a rare opportunity to gain a wide spectrum of experience with semiconductor device design, nano-fabrication, nano-optics, laser spectroscopy, cryogenics, electron spin resonance, machine learning and sophisticated electronics. The research is multi-disciplinary, involving condensed-matter physics, quantum optics, materials science, and quantum information processing. We offer a world-class laboratory and a strong network of international collaborators. Please send inquiry emails to Prof. Brian Gerardot (b.d.gerardot@hw.ac.uk), Dr Cristian Bonato (c.bonato@hw.ac.uk) or Dr Margherita Mazzera (m.mazzera@hw.ac.uk)

Project 1: Novel platforms for integrated quantum devices based on rare earth doped insulating materials

This project aims at the development of new telecom-compatible platforms for integrated quantum devices based on rare earth ion doped materials. This will involve the investigation of the mechanisms affecting the optical and spin coherence properties of new materials and the design of confined structure with the aim of achieving improved performances due to the strong light matter interaction and facilitating the coupling with other integrated quantum technologies as quantum light sources or detectors.

Project 2: Strongly correlated states in designer two-dimensional moiré heterostructures

Two-dimensional semiconductors offer unprecedented opportunities to engineer and tune the interactions between particles at the quantum level to give rise to emergent phases and states of matter. This project aims to design, fabricate, and characterize (via quantum transport and quantum optics) highly tunable moiré heterostructures which act as a quantum simulator of the Hubbard model.

Project 3: Engineering scalable coherent coupling among artificial atoms

Photon mediated communication between matter qubits provides a versatile quantum optics platform to realize scalable quantum technologies. This project aims to engineer a novel on-chip semiconductor platform to coherently control coupled artificial atoms in a scalable approach, providing a means to entangle multiple qubits and realize Dicke superradiance and other unique states of quantum light.

Project 4: Controlling spins in silicon carbide devices

A single spin is the smallest possible magnetic field sensor, providing the ultimate limit in spatial resolution and sensitivity. Additionally, spins are excellent systems to store and process fragile quantum information. The goal of this project is to develop spin-based opto-electronic quantum devices based on spins in silicon carbide. As a semiconductor widely used in microelectronics, silicon carbide is a promising platform to integrate spintronic functionalities in quantum devices compatible with the current industrial processing techniques. A strong emphasis of the project will be on taking full advantage of the well-established micro-electronic SiC technology to develop novel spin control and measurement techniques.

Project 5: Sequential Bayesian estimation and machine learning for quantum sensing

Recent breakthroughs have demonstrating the capability of quantum sensors for measuring magnetic fields, temperature and electric field at the nanoscale. The deployment of these techniques are, however, limited by long signal acquisition times.
In this project, we will use real-time adaptation of experimental parameters and machine learning to optimise measurements to the limit, in order to reduce the number of required measurements.
