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 ...
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, ...
Expectation Expectation value Quantum and general physics Quantum basics Value Wave function Wave functions In summary: I understand that the integral is supposed to be$$ int( x * e^(-2*a ( (m*x^2 / hbar) ) dx) = x * A^(-2) - int( A^(-2) * 2 * x dx) = x * A^(-2...

In measuring the x component of angular momentum of a state, by using the expectation value calculation of Lx, i got i/3 h bar - i/3 h bar, does this means that the probability of h bar is i/3 and the probability of 0 h bar is 0 and the probability of -h bar is i/3...

Noise in existing quantum processors only enables an approximation to ideal quantum computation. However, for the computation of expectation values, these approximations can be improved by error mitigation. This has been experimentally demonstrated in small systems but the scaling of these methods to lar...
Explain. If \vec{F} is conservative, what is the potential-energy function for it? Let U=0 when x=0 Why is it important that a wave function is normalized? a) Explain why hermitian operators are important in quantum mechanics. b) Use the expression for the mome...
each one being an eigenvalue of the associated observable, but only the probabilities can be determined of these possible results. This physically observed state-of-affairs is reflected in the mathematical structure of quantum mechanics in that the eigenstates of the observable form a complete...
