Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons
Curves in spacetime violate Heisenberg's uncertainty principle
Quantum strategies fail to improve capacity of quantum optical communication channels
You don't exist in an infinite number of places, say scientists
Best of Last Week—New violations of local realism, a computer that runs on water droplets and nuts warding off diseases
Entangled photons unlock new super-sensitive characterisation of quantum technology
A new protocol for estimating unknown optical processes, called unitary operations, with precision enhanced by the unique properties of quantum mechanics has been demonstrated by scientists and engineers ...
New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic ...
Quantum correlation can imply causation (Update)
Does taking a drug and then getting better mean that the drug made you better? Did that tax cut really stimulate the economy or did it recover on its own? The problem of answering such questions - of inferring ...
Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the ...
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 ...
Correlations of quantum particles help in distinguishing physical processes
Communication security and metrology could be enhanced through a study of the role of quantum correlations in the distinguishability of physical processes, by researchers at the Universities of Strathclyde ...
