We find that in this framework quantization of the usual Regge calculus is defined up to a parameter. The theory may possess nonzero (of the order of Planck scale) or zero length expectation values depending on whether this parameter is larger or smaller than a certain value. Vanishing length...
The time dependence of the wave function gives rise to time dependence of the expectation value of observables. We have been exploring the difficulties that advanced undergraduate and graduate students have with time dependence of expectation values in quantum mechanics. We have developed and ...
Recently, I started with principles of Quantum Mechanics by R.Shankar, and I got stuck at a part in my calculation of the Expectation value of Position and Momentum operator in the case where the particle is in one of the states. Starting with the Momentum operator, the eigenstates are ...
Open in MATLAB Online Download In general, the expectation value is the average over all measurement outcomes, weighted by their probability of occuring. Expectation values are a fundamental concept and arise in many quantum computing applications. This contribution allows you to: ...
expectation value Also found in:Dictionary,Thesaurus,Financial,Acronyms. [‚ek‚spek′tā·shən ‚val·yü] (quantum mechanics) The average of the results of a large number of measurements of a quantity made on a system in a given state; in case the measurement disturbs the state, ...

The following code example illustrates how to define a tensor network state and then compute its Matrix Product State (MPS) factorization, followed by computing the expectation value of a tensor network operator over the MPS-factorized state. The full code can be found in the NVIDIA/cuQuantum re...
