Subject: colloquium 7/10 by Douglas Paul (Director of James Watt Nanofab Centre)

Dear All,

Please note next week's colloquium (at usual time and place)!
speaker:  Prof Douglas J Paul
title:  Engineering Quantum Platforms for Applications and New Science

on Wednesday 7 October
in room 257

We will have coffee and doughnuts in the common room after the talk, from 4pm until 5pm.
If you would like to talk to Douglas in more detail before his talk let me know and I will arrange a schedule - he'll be here from 12:30.


Prof Douglas J Paul
Director of the James Watt Nanofabrication Centre

The UK has embarked on a large £300M programme of work to turn quantum technology into practical systems for applications. I am leading 6 projects in the James Watt Nanofabrication Centre to develop platform quantum technologies that will allow the quantum processes of superposition, entanglement and squeezing to be built into turnkey systems for applications. These platforms can also be used for new quantum science allow scientists to concentrate on the science rather than spending years building new experiments in the laboratory.
The first platform is to develop cold atom systems using semiconductor diode lasers magneto-optical traps and miniature vacuum systems to allow portable atomic clocks, quantum navigators, electromagnetic sensors and gravity imagers to be developed. The technology is also being used by many physicists to study Bose-Einstein condensates, quantum computation and the fundamentals of quantum mechanics.
The second area is to develop a Si quantum photonics platform starting from the recent Si photonics platform that has been developed for telecoms, fibre to the home and data-centre comms. I will provide an overview of the basic Si photonics technology before demonstrating the first Geiger mode operation of Ge on Si single photon avalanche detector and how chi^3 allows mixing and entanglement. I will then explain some of the work in Engineering to develop chi^2 elements for integrated optical parametric oscillators. This work is aiming to develop compact squeezed light sources and detectors all on a silicon chip for sub-shot noise detection for a range of sensors and interferometers. We are also working with the University of Bristol who want to use these systems to develop quantum simulators and computers. As an example I will explain how we are working with the Institute of Gravitational Research to develop MEMS gravimeters ultimately using squeezed light interferometers integrated into the MEMS devices.
Finally I will show a Si nanowire technology that we are working with NPL and NIST to develop the new current standard which is being redefined in 2018. Using Si nanowire technology very similar to that being developed for the 7 nm CMOS technology node by industry, we can produce 1D electron transport, quantum dots and adiabatic turnstiles when biased in the Coulomb blockade regime. I will explain some of the work we are undertaking to develop the current standards plus qubits with the University of Oxford.
