Laser technique promises super-fast and super-secure quantum cryptography

A new method of implementing an ‘unbreakable’ quantum cryptographic system is able to transmit information at rates more than ten times faster than previous attempts. The research featured in a recent Nature Photonics paper and the first author was CDT PhD student Lucian Comandar. Reproduced courtesy of the University of Cambridge (

Using Optics to do Neuroscience: video about fNIRS

Dr Tachtsidis a CDT supervisor and his team from UCL Medical Physics in collaboration with neuroscientists from the Institute of Cognitive Neuroscience in UCL have demonstrated the use of functional Near-Infrared Spectroscopy (or fNIRS, an optical technique for monitoring brain function) to investigate prefrontal cortex function, during a prospective memory task in freely moving subjects in the center of London.

Research-industry links present at IPES CDT Industry Day 2016

The benefits of having strong links between research and industry were highlighted at the Integrated Photonic and Electronic Systems (IPES) Industry Day that took place at University College London (UCL) on 14 January 2016.

Nobel prize awarded for optical super-resolution microscopy

The inventors of single molecule localisation and stimulated emission depletion (STED) super-resolution microscopy were today honoured with the Nobel prize for chemistry. One of the key applications of super-resolution imaging, pioneered by Professor Clemens Kaminski, (a CDT Supervisor at Cambridge) and mentioned by the Nobel Assembly, is the study of protein aggregation reactions in the context of neurodegenerative diseases.
