Extracting hidden quantum information from a light source

Researchers at ICFO-The Institute of Photonic Sciences report on a technique to extract the quantum information hidden in an image that carries both classical and quantum information. This technique opens a new pathway for quantum enhance microscopes that aim to observe ultra-sensitive samples.

Current super-resolution microscopes or microarray laser scanning technology are known because of their high sensitivities and very good resolutions. However, they implement high light power to study samples, samples that can be light sensitive and thus become damaged or perturbed when illuminated by these devices. Thus, launched a year ago, the European project Q-MIC has gathered an international team of researchers with different expertise who have come together to develop and implement quantum imaging technologies to create a quantum enhanced microscope that will be able to go beyond capabilities of current microscopy technologies.

In a study recently published in Sciences Advances, researchers Hugo Defienne and Daniele Faccio from the University of Glasgow and partners of the Q-MIC project, have reported on a new technique that uses image distillation to extract quantum information from an illuminated source that contains both quantum and classical information.
