A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring minute ...

Quantum‐enhanced measurement harnesses non-classical states of light to surpass classical limits of sensitivity in a range of optical instruments. Central to this endeavour is the generation and ...

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 ...

Researchers have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. (Nanowerk News) ...

Attosecond photon pulses are used to investigate dynamical processes in matter with unprecedented temporal resolution (Credit: iStock/7io). Experimental attosecond science is built around the ability ...

For the light from faraway stars and galaxies to reach and be detected by our telescopes, it first has to beat the odds. Of the photons of light that avoid clouds of dust and other deep-space ...
