Our first cohort have now begun their projects with a number of different groups. Find out more about them below:
Implementing a Metropolitan-Scale Quantum Key Distribution Network for Unconditionally Secure Communications
Alasdair graduated from the University of Sussex in 2014 with a first class honours MPhys in Physics. In 2012, he began working as part of Dr. Winfried Hensinger’s Ion Quantum Technology Group. He would later undertake a final year project under Dr. Hensinger’s supervision, focusing on microwave systems for ion-trap quantum computing. Alasdair also spent some time teaching undergraduate-level Physics at the University of Sussex International Summer School. Since moving to Bristol, he has begun to explore integrated photonics, which can be used for a wide range of quantum technologies. In his spare time he is a violinist with one of the university orchestras,and a semi-professional magician.
Sub-shot noise measurements via Kerr non-linearities
Euan trained as an experimental physicist and graduated in 2013 with an MPhys from The University of Manchester. During his degree, Euan spent time working with the University of Oxford and DSTL (one of the CDT's industrial partners). His masters projects were on the propulsion mechanisms of micro-organisms and mammographic imaging techniques. After graduating, Euan started a science blog and worked for Techniquest, a science learning centre based in Cardiff. Euan came to join us in 2014 after a three month trip around North America.
A scalable quantum dot solid-state photon source
Janna graduated in 2013 with a first class BSc in Mathematics and Music from Leeds University, before joining their physics department to study for an MSc in Quantum Technologies and graduating with a distinction. Her MSc dissertation was to prove the unconditional security of a newly developed quantum key distribution protocol using both analytical and numerical methods under the supervision of Dr Almut Beige. Janna is a keen musician and has played professionally in several orchestra pits for musical societies in her free time.
A Silicon Four Photon Cluster State Generator
Jeremy graduated with a first class MSci in Mathematics and Physics from Bristol University in 2014. For his final year project, supervised by John Rarity, Chengyong Hu and Ruth Oulton, he modelled quantum dots in lossy optical cavities using the Lindblad master equation in order to evaluate cavity-state conditional phase changes and optical switching, with potential applications in photonic quantum information processing. He is also interested in developing the photonic microchip technology used at Bristol, in particular the integration Quantum Dot systems for deterministic single photon sources. He is a keen bassist and has an all round interest in all things musical.
Superconducting Nanowire Single-photon Detectors: Integration onto linear optics chips and use in novel quantum information experiments
Mack graduated with first class honours in the Chemical Physics MSci at the University of Bristol in 2014. As part of his degree, he carried out an industrial placement at the Atomic Weapons Establishment (AWE), during which he used various types of spectroscopy (Raman, FTIR, EDX, ATR, DRIFT) to study the reactivity of lithium hydride during exposure to ultraviolet light. His final year project was with Professor Mike Ashfold and Dr. Ben Truscott working on microwave plasma-activated chemical vapour deposition of diamond. In particular, the project focused on analysing plasma characteristics using Colin Western's unique PGOPHER software when nitrogen was added as a precursor gas. Outside of university his other interests are in music, combat karate, rally, and reading.
Photonic Integration of Ion Microtrap Arrays
Matthew trained as a theoretical physicist at the University of Southampton. For his Masters project he modelled how an inhomogeneous matter distribution affected the way the universe expands. After completing his degree he moved to Toronto for a year where he decided he wanted to use theoretical physics to make novel technologies. Matthew's PhD is funded by a DSTL grant and will focus on integrating ion trap optics onto microchips. This project combines the expertise of Bristol’s photonics with NPL’s trap technologies, leading the way to a compact ion trap package that could be commercialised for use in metrology, timing or quantum computing. Outside of physics, Matthew is also interested in cycling and all things coffee related.
The development of theoretical techniques to solve practical problems facing Linear Optical Quantum Computation
During his undergraduate degree in Physics at the University of Sheffield, Sam became particularly interested in Quantum Mechanics and went on to complete his Master’s project under the supervision of Dr. Pieter Kok. His project looked at the effect of a Hilbert space’s dimensionality and structure upon the dynamics of states within them, with a special interest in the state’s potential distinguishability. This work was then published on the arXiv and more recently in Physics Review A. At Bristol Sam is still undecided about whether his PhD will take a theoretical or a experimental direction, but is very excited to get to experience in both during his first year at the CDT and is keen to get involved with the integrated photonics work currently at large within the Centre for Quantum Photonics here.
Verification and Characterisation of Quantum Devices
Prior to joining the CDT, Sam completed an MSc in Quantum Technologies at the University of Leeds, with a thesis concerning interaction schemes in discrete time quantum walks (with application in trapped ion experiments). He also has an integrated Masters degree in physics with theoretical physics from Imperial College London; here, he focussed primarily on cosmology and quantum gravity. His MSci thesis examined the role causality plays in the structure of spacetime, and whether spacetime itself is discrete or continuous. His research interests at Bristol are theoretical and foundational issues in quantum information.
Distinguishability and Pseudorandomness in Quantum Information
After attending the Mathematical High School in Belgrade, Serbia, and competing at a variety of national, regional and international science competitions, Stasja carried on her education at California Institute of Technology. During her studies there, she pursued different science interests with a particular focus on Physics and Computer Science, graduating with a BSc in Computer Science in 2012. She then worked as a software engineer for a Bristol networking startup Gnodal Ltd, and was part of the engineering team acquired by Cray Inc. in 2013. During her employment, she took Masters level classes in Mathematical Analysis at the University of Bath and tutored a first year Analysis course. Her research interests include quantum information and the foundations of quantum mechanics, as well as mathematical physics and (quantum and non-quantum) machine learning.
Quantum Illumination and the Invisible Rangefinder
Stefan started his studies in Physics (B.Sc.) in 2007 at the Ludwig-Maximilians University in Munich. For his final project Stefan built a laser beam pointing system for a 500 meter free-space QKD link. Stefan then continued his studies and obtained his Masters degree in 2013. His final project was on hand-held QKD systems using integrated optical waveguides. Alongside his studies Stefan also worked as a research assistant in Prof. Harald Weinfurter's group, where he was involved in an experiment successfully demonstrating a QKD link between an air-plane and a ground station. From 2011 to 2013 he worked as an R&D engineer at quTools GmbH and afterwards joined Prof. John Rarity's group as a visiting student before joining the CDT as a doctoral student in 2014.
