How would you look for something that can be in two 'places' at once? The answer, according to Oxford University research into a quantum phenomenon called superposition, seems to be to ask where it isn't rather than where ...

(Phys.org) —A team of physicists in Israel has used the scattering of a photon when it strikes an atom to better understand the process of decoherence. In a paper the team has published in the journal Science, the group ...
In this month's special edition of Physics World, focusing on quantum physics, Thomas Jennewein and Brendon Higgins from the Institute for Quantum Computing at the University of Waterloo, Canada, describe how a quantum space ...

(Phys.org)—Quantum physics presents several counterintuitive features, including entanglement, tunneling and – as demonstrated in double-slit experiments – wave-particle duality. When studying wave-particle duality, ...
(Phys.org)—If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits—-tiny ephemeral quantum cells held in a superposition of internal states—-will ...

(Phys.org)—As understood in the field of quantum mechanics, objects are able to exist in more than one state at a time, a property known as superposition. Measuring such states is a challenge however, as doing so causes ...
(Phys.org)—Former and current USC Dornsife physicists have led a study that represents the first, quantitative account of the universal features of disordered bosons—or quantum particles—in magnetic materials.
