Squeezed light produced using silicon micromechanical system

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, ...

Closing in on Einstein's window to the universe

(Phys.org) —Nearly a century after the world's greatest physicist, Albert Einstein, first predicted the existence of gravitational waves, a global network of gravitational wave observatories has moved a step closer to detecting ...

Physicists publish solution to the quantum measurement problem

(Phys.org) —Quantum mechanics is a highly successful theory, but its interpretation has still not been settled. In their recent opus magnum, Theo Nieuwenhuizen (Institute of Physics, UvA) and colleagues claim to have found ...

Cold atoms for quantum technology

Researchers from the National Physical Laboratory, University of Strathclyde, Imperial College London and University of Glasgow have developed a portable way to produce ultracold atoms for quantum technology and quantum information ...
