A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy. Physicists from The University of Queensland have performed joint measurements on ...
Until recently measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones. Researchers at the ...

By making constant but weak measurements of a quantum system,physicists have managed to probe a delicate quantum state without destroying it–the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it.The ...
