4. The wavefunction of a particle at t = 0) is given by: 4(x,0) = Cexp( ), Xo = real constant (a) Sketch the wavefunction and normalise it to find |C|. (The sketch should help to suggest how to select the method of integration.) (b) Determine the probability of finding the particle at a value of x between –a and a, ie. -a < x < a. [7] [8]
2.2 Two-level system A particle in the box is described by the following wavefunction 1 1 V(x, t) + V2 V2 = Um(x)e -i(Em/h) In other words, this state is a superposition of two modes: n-th, and m-th. A superposition that involves only two modes (not necessarily particle in the box modes, but any two modes) is called a "two-level system”. A more modern name for such a superposition is a "qubit”. a) Come up with an expression for the...
