Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Get a clear overview of Physics Chapter 1, focusing on units, measurements, and scientific notation. This video explains how physicists use standard units and powers of ten to express physical ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has successfully developed a length measurement system that achieves a level of precision approaching the ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

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.

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 ...
