2017-05-16: New paper
Our manuscript The spin resonance clock transition of the endohedral fullerene 15N@C60 is online on the arXiv.
A portable condensed-matter atomic clock would have important technological applications in navigation, communication, and sensing. We have shown that endohedral fullerene molecules, already a promising material for quantum technology because of their well-isolated spin states, also have a "clock transition" at which the energy levels are immune to many types of noise. This transition may one day be exploited in chip-scale portable clocks that could operate in cellphones.

2016-11-29 Postdoctoral vacancy: Microwave-to-optical Conversion using Molecular Spin Ensembles
We are seeking a Postdoctoral Researcher to join an international collaborative project to create a comprehensive formalism for the description and control of classical and quantum networks. You will have specific responsibility for development of quantum coherent microwave to optical frequency conversion, a goal with wide technological and scientific importance.
You will work on experimental development of quantum coherent microwave to optical conversion, and testing the systems using the hardware-in-the-loop facility. You will also contribute to foundational questions about the nature of quantum networks.
You will have a good first degree and have completed (or be close to completing) a doctorate in the physical sciences. You will also demonstrate expertise in one or more of the following: (a) synthesis and assembly of relevant molecules and materials, (b) superconducting resonators, (c) electron spin resonance, (d) optical molecular spectroscopy, including at low temperature.
For more details and to apply, see the university's jobs page.

2016-08-01 New project: The physics of the observer
Prof. Andrew Briggs, Dr. Natalia Ares, and Dr. Edward Laird have won a grant from the Foundational Questions Institute to investigate gravity as an observer of quantum states. In some theories of quantum gravity, decoherence leads to a weak heating effect. We will investigate the feasibility of detecting this heating in an optomechanical experiment. We are particularly pleased that this project introduces a formal collaboration with Gerard Milburn at the University of Queensland..

2016-07-015 New project: The nature of quantum networks
We are delighted to be taking part in the joint theoretical and experimental project "The nature of quantum networks". The project, funded by John Templeton Foundation with €1.45M and led by Joerg Schmiedmayer at TU Vienna, will aim to provide a unified formalism for quantum effects in networks and provide first experimental bounds for physical properties of such networks. Andrew Briggs, Edward Laird, and Lapo Bogani from Oxford will collaborate with colleagues in Vienna, Budapest, NII (Tokyo), and IT Lisbon. It will kick off with a workshop in Obergurgl, Austria in April 2017. Among our first discoveries on this project is that Obergurgl is the name of a real place. |

2016-04-06 Two popular videos
We have been collaborating with the motion graphic designer and science populariser Dominic Burgess to create videos inspired by our work. He has produced two excellent youtube shorts explaining endohedral fullerenes (the world's most expensive material ... almost) and atomic clocks. Enjoy!
