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...
Expectation Values The expectation value of an operator in quantum mechanics is the expected value of the operator, and can be considered to be a type of average value of the operator. It is not necessarily the most probable value. For example, in the case of a particle in a ...
i am then asked to calculate the expectation values of x, x^2, p and p^2 so starting with the expectation value of x (i will write this as <x>) : from calculating A i already know that int( e^( -2*a ( (m*x^2 / hbar) ) dx) = ( pi * hbar / (2*a*m) )^( 1 /...

Another example, occurring in integration theory, is the set [X→s[0,1]] of simple functions X→[0,1], having only finitely many output values (also known as ‘step functions’). A morphism E→D in the category EMod of such effect modules is a function f:E→D between the ...
But since these variables are random, they do not fully represent the corresponding dynamical system, and therefore, they should be complemented by the information about all the other possible values that would occur had the system run again with the same initial conditions. This means that the ...
quantum mechanics. In section IV we explicitly calculate the momentum expectation values in various potentials and show that in bound states we always get the expectation value of the linear momentum to be zero. Section V gives a brief discussion on the Ehrenfest theorem when we are using it to...
