An introduction to the Quantum Mechanics of light, and how it gives rise to peculiar properties which are taken advantage of in new communication and imaging applications.
Entanglement is the quintessential quantum phenomenon, given a "spooky" link between the properties of objects at a distance.
We study this quantum world through the use of light beams which we both create and measure holographically. Beyond exploring this quantum world, we use entanglement to make better communication, sensing and imaging systems.
We are happy to discuss a PhD proposal that is of interest to you and aligned to our own scientific ambitions. Feel free to get in touch.
