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

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

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

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 ...

(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 ...

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; ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation ...

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 ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem ...

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 ...
