Quantum optics with an atomic vapour: entangled images and super-resolution 

The entanglement properties of two beams of light can reside in subtle correlations that exist in the unavoidable quantum fluctuations of their amplitudes and phases. I will review recent advances in four-wave mixing in an atomic vapour which have enabled the production and the observation of "entangled images", that is to say beams of light which are entangled "point per point" across their transverse profiles. These beams can carry quantum information not only in their average profile but also in their spatial details, opening up the field of quantum imaging.

The introduction of the spatial degrees of freedom into quantum optics lets us envision novel applications for quantum light. As an example, I will present our current efforts to improve optical super-resolution beyond the standard quantum limit.

UKRI Deadlines

Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.

The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:

EPSRC New Investigator Award

EPSRC Network Grant

EPSRC Post Doctoral Fellowship

EPSRC Open Fellowship

EPSRC Open Plus Fellowship

EPSRC Working with overseas scientists

EPSRC Standard research grant

EPSRC Discipline hopping in ICT

EPSRC Overseas travel grant
