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
Physicists extend entanglement in Einstein experiment
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 ...
Researchers describe the wavefunction of Schroedinger's cat
Schrödinger's cat highlights a long-standing dilemma in quantum mechanics: is the cat really alive and dead, or is the weirdness just in our head?
Best of Last Week – Setting a quantum speed limit, slowing the speed of light and turning back the aging clock
Scientists set quantum speed limit
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to ...
Scientists tame Schrodinger's cat for a new type of quantum computer
Physicists at the University of Sussex have tamed one of the most counterintuitive phenomena of modern science in their quest to develop a new generation of machines capable of revolutionizing the way we ...
Extending Einstein's spooky action for use in quantum networks
An international team, including researchers from Swinburne University of Technology, has demonstrated that the 1935 Einstein-Podolsky-Rosen (EPR) quantum mechanics paradox may be extended to more than two ...
