An exciting opportunity has arisen for a Cotutelle PhD, jointly located in two world-class photonics and quantum optics laboratories. The University of Bristol, UK, and Macquarie University in Sydney, Australia have joined forces on a project to design and demonstrate the most efficient and flexible quantum photonic circuit yet made.
During this Cotutelle PhD, you will spend approximately 50% of your time during the 3.5yrs of your PhD in each location, gaining expertise and a unique perspective of research from both institutions. You will obtain a PhD from both Universities. Exact details of the project and research time plan is flexible depending on previous experience.
Both institutions offer unique world-class research environments, embedded in an entrepreneurial environment.
Your PhD will involve designing and fabricating state-of-the-art laser-written glass 3D photonic waveguide circuits at Macquarie University, and combining fabricated circuits with extremely efficient quantum dot entangled photon sources in the Quantum Engineering Technology Labs (QET Labs) at the University of Bristol. Non-classical light states input into these circuits promise an array of functionalities: processing photons into higher dimensional orbital angular momentum entangled states; constructing a 2D lattice of entangled photons robust to decoherence; potentially even using such states to demonstrate that photon entanglement may outperform classical calculations.
The Quantum Engineering Technology Labs (QET Labs) has over 100 researchers and encompasses an ecosystem of quantum technology research, training and innovation in Bristol. This includes activities such as the Quantum Technology Enterprise Centre, our entrepreneurship fellowship programme, and alignment to the Quantum Technology Innovation Centre, a centre for supporting quantum industries. QET Labs has produced world-first demonstrations in integrated quantum photonic technology, including the most complex photonic integrated circuit ever created [Carolan et al, Science 2015]. Similar circuits will be developed in this project. In 2018 we reported very efficient Quantum Dot single photon devices with the largest non-linearity ever demonstrated with a solid-state quantum emitter [Androvitsaneas et al, ACS Photonics 2019] again very similar to the structures to be used in this proposal.
The Department of Physics and Astronomy at Macquarie University has over 20 academic staff and 60 researchers overall working in the areas of theoretical and experimental quantum information science, quantum optics, photonics and laser science. We host a node of the Centre of Excellence for Engineered Quantum Systems and are a partner in the newly established Sydney Quantum Academy which has joined four Sydney universities active in quantum science to promote the development of quantum industry, innovation and investment in New South Wales. The PhD project will make extensive use of Macquarie’s world class femtosecond laser writing facilities based in the OptoFab laboratories. The Department is one of the leading research units in the University and has a strong record of research translation in photonics and quantum science. We are active proponents of a positive workplace culture and have recently received silver status in Australia’s Pleiades awards scheme for equity, diversity and inclusion in physics and astronomy departments.
