(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 ...
(Phys.org)—Theoretically, the laws of quantum mechanics – particularly the "no-cloning theorem" – guarantee that any attempt at counterfeiting a credit card, bill, coin, token, etc., will fail if the object is embedded ...
(PhysOrg.com) -- Decoherence can be metaphorically seen as a quantum fall from grace: When quantum bits, or qubits, are in superposition – such as a single qubit simultaneously having both 1 and 0 values – they’re ...
(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs its behavior.
