A new method for measuring three different properties of light, at the same time, has been developed using an interferometry-based quantum sensing scheme capable of simultaneously estimating multiple parameters of an optical network.
The approach could help advances in the fields of medicine and astronomy, for example, to improve the precision and scope of quantum measurements across applications ranging from biological imaging to gravitational wave detection.
To date, it has only been possible to measure each parameter individually. However, research published in The European Physical Journal Plus has demonstrated, for the first time, that three independent optical parameters can be measured in a single “view” with ultimate quantum precision, without the need to examine each one of them individually.
