Creation of entanglement simultaneously gives rise to a wormhole
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics—so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."
Teleportation just got easier—but not for you, unfortunately
Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? ...
Researchers propose using distant quasars to test Bell's theorem
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if vio ...
Repulsive gravity as an alternative to dark energy (Part 2: In the quantum vacuum)
Atom and its quantum mirror image
A team of physicists experimentally produces quantum-superpositions, simply using a mirror.
New principle may help explain why nature is quantum
Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers ...
Physicist disentangles 'Schrodinger's cat' debate
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
Improving measurements by reducing quantum noise
If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface forces, ...
Four reasons why the quantum vacuum may explain dark matter
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
'Spooky action' builds a wormhole between 'entangled' quantum particles
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as "spooky action at a distance," could be even spookier than Einstein perceived.
Vienna physicists create quantum twin atoms
At the Vienna University of Technology, sophisticated atomchips have been used to create pairs of quantum mechanically connected atom-twins. Until now, similar experiments were only possible using photons.
