Quantum physicists have found a way to let a single qubit experience several different “journeys” through time at once, effectively bending a classic limit on how fast quantum systems are allowed to ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

Physicists have placed part of a sapphire crystal into a quantum superposition, making it the heaviest object to show quantum effects, in a new take on Erwin Schrödinger's famous cat experiment. When ...

Quantum mechanics, when examined closely, poses some deep questions about reality. These questions often take the form of thought experiments, which are later (usually much later) followed up by real ...
