The next meeting of the Institute of Physics in Scotland Young Members Group (IOPS YMG) will take place at 18:30 on the 10th of December at the University of Edinburgh (50 George Square - Screening Room G.04). We have two speakers who will talk about their research in Quantum Optics so please join us to learn more about this fascinating topic.

Imaging at the speed of light
How do you take images so fast that you can see light travelling through air? And how do you use the latest technology to look around corners and see objects hidden from view? These are the questions that we are looking to answer at Heriot-Watt University. Our research is focused on developing new strategies for imaging which allow us to see the world in a new perspective.
I will talk about our recent research using a very specialised camera with some very important features. The first is its sensitivity to single photons – each pixel is around ten times more sensitive than a human eye; the second is its speed – each pixel can be activated for just 67 picoseconds, that’s more than a billion times faster than you or I can blink. The camera allows us to film at the speed of light – we can video pulses of light as they travel through air. One application of this technology is looking around corners to see objects hidden from view.

Building new quantum technologies from the atom up: atomic clocks and more Quantum and atomic physics are well over 100-years old. To many, they might appear to be rigorous academic subjects that don’t have much influence on the real world outside of a university. However, they are the direct parents of semiconductors and lasers, two technologies that are central to the modern world. Since these innovations, the research fields have continued to progress and now allow for the most precise agreements between theory and experiment.
There is now a push to make new technologies, that take the sensitivity and accuracy of the research lab and to develop devices that will give industry and society new advantages, what has become known as Quantum Technologies. In this talk I will discuss my work, as part of the UK Quantum Technology Hub program, to build next-generation atomic devices that advance the existing state of the art. Central to this are robust and portable atomic clocks that will be the basis for a faster and more secure internet, as well as much more accurate satellite navigation systems.
