Team tightens bounds on quantum information 'speed limit'

If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards ...

The first ever photograph of light as both a particle and wave

(Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded ...

Quantum computer as detector shows space is not squeezed

Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions - that it's not squeezed in one direction relative ...

Three's a charm: NIST detectors reveal entangled photon triplets

Researchers at the University of Waterloo in Canada have directly entangled three photons in the most technologically useful state for the first time, thanks in part to superfast, super-efficient single-photon detectors developed ...

Fluid mechanics suggests alternative to quantum orthodoxy

The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what's ...
