Calculate density of probability.

  1. Oct 24, 2015 #1
    1. The problem statement, all variables and given/known data
    Given a quantum density ρ=w1|φ1><φ1|+w2|φ2><φ2|
    where φ1=c(1/2)*exp[-(x-b)2/2c2]
    φ2=c(1/2)*exp[-(x+b)2/2c2]
    find the density of probability of finding x0 if X(operator) is measured
    2. Relevant equations
    PA=Σwi(Σ|<a;α|φi>|2)

    3. The attempt at a solution
    I know that the probability of measuring a x0 is Tr(ρΣ|x0><x0|), but I don't know how to calculate the projector.

    All help is welcome.
