Sentences with phrase «quantum measurement»
"quantum measurement" refers to the act of observing or checking the properties of a quantum system. It involves interacting with the system in such a way that it can provide information about its state. This process can include things like detecting the position, momentum, or energy of a particle. A quantum measurement can cause the system to change its state, which is a fundamental characteristic of quantum mechanics. Full definition
In his concern for the nature of quantum measurements, Wheeler is addressing one of the most confounding aspects of modern physics: the relationship between the observations and the outcomes of experiments on quantum systems.

John is interested in the significance of quantum measurement, how it creates an actuality of what was a mere potentiality.
Finally, getting a useful answer from the calculation proved to be quite difficult due to intricacies with the inherently probabilistic nature of quantum measurement.
Steve: «The many worlds interpretation [asserts] that quantum measurement in effect split the universe into branches where all the different outcomes occur in parallel, so your universe can be local if copies of you inhabit myriad unseen parallel universes.
Similarly, in the many - worlds hypothesis, new «universes» are spawned with every quantum measurement.
