In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

So, back in the 1950s, a young physicist named Hugh Everett III was working on his PhD. He was wrestling with this really ...

Scientists in Wales have built the world’s most sensitive table-top interferometer, which is a miniature, ultra-precise ...

Experimental physicist David Weld’s experimental research interest lies in a question that has been around for a long time, but which we’re only now approaching the ability to investigate. “There’s a ...

There are three types of quantum physicists: (1) those who think quantum mechanics is defaced by a so-called measurement problem; (2) those who think, as I do, that there is no measurement problem; ...

(via PBS Space Time) The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

Many governments and tech companies are investing heavily in quantum technologies. In New Zealand, the recently announced ...

The quantum world and our everyday world are very different places. Physicists now investigate how the act of measuring a quantum particle transforms it into an everyday object. The quantum world and ...

Gao (Synthese, 2017. https://doi.org/10.1007/s11229-017-1476-y) presents a new mentalistic reformulation of the well-known measurement problem affecting the standard ...
