The phrase "a quantum measurement" is correct and usable in written English.
It can be used in contexts related to physics, particularly in discussions about quantum mechanics and the process of measuring quantum states.
Example: "In quantum mechanics, a quantum measurement can fundamentally alter the state of the system being observed."
Alternatives: "a quantum observation" or "a quantum assessment".
Vaidman 2012 believes that to derive the Probability Postulate, at least some connection between the mathematical formalism of quantum mechanics and probability has to be postulated and points out that it is enough to assume that the probability of an outcome of a quantum measurement depends only on the measure of existence of the corresponding world.
— has hard scientific consequences: because of it, they take radically opposed views of what is going on when a quantum measurement is made.
"I think it's marvelous," says Wojciech Zurek, a quantum measurement guru at the Los Alamos National Laboratory in New Mexico.
The results of the computation are obtained by carrying out a quantum measurement on the molecule.
"Energy per orbit" refers to consumption per one full orbit while performing a quantum measurement and takes into account different operation times for each device.
We also discuss the read-out, i.e., a quantum measurement process, which is accomplished by coupling a dc-SQUID to the qubit.
This probabilistic nature of particles means there will always be imprecision in any quantum measurement, no matter how little that measurement disturbs the system it is measuring.
A controversial quantum measurement that seems to bend the rules may not be very quantum after all.
Second, using the quantum equilibrium hypothesis, that it randomly collapses according to the usual quantum mechanical rules under precisely those conditions on the interaction between the subsystem and its environment that define an ideal quantum measurement.
Part of what is meant by this decoupling is that Ψ has a special form, what might be called an effective product form (similar to but more general than the superposition produced in an "ideal quantum measurement"), in which case the conditional wave function of the subsystem is also called its effective wave function.
The formalism presented in this article facilitates the design of a class of quantum measurement devices, with applications in fault-tolerant quantum computing architectures and remote entanglement preparation.
