Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

Quantum physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough ...

Scientists have explored how quantum squeezing can improve measurement precision in complex quantum systems, with potential applications in quantum sensing, imaging, and radar technologies. These ...

(Nanowerk News) Quantum squeezing is a concept in quantum physics where the uncertainty in one aspect of a system is reduced while the uncertainty in another related aspect is increased. Imagine ...

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 ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...

Have you ever struggled with the concept of quantum measurement, feeling it’s unnecessarily abstract? You’re not alone. Enter this guide by [Mithuna] from Looking Glass Universe, where she circles ...
