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

Many World’s lack wavefunction collapse might be the key to the measurement problem. The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem ...

Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

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; ...

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 ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Researchers Mitsuyoshi Kamba, Naoki Hara, and Kiyotaka Aikawa of the University of Tokyo have successfully demonstrated ...

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 ...
