A note on this problem is "this beamsplitter IS polarization sensitive"

Step 1

It is mentioned in the problem that the photon polarized in vertical direction is incident onto a polarizer.

Let the direction of polarization along the *x *axis be denoted by the ket |*x*> and the direction of polarization along the *y *direction be denoted as | *y*>

Let the angle which the transmission axis forms with the horizontal be denoted by *θ*.

Let the ket corresponding to the state of the transmitted photon when *θ* is measured counterclockwise from the horizontal *x* direction to the vertical *y* direction be denoted by | *θ*>

This ket | *θ*> can then be represented as a linear superposition of the linearly independent basis orthonormal basis kets |*x*> and | *y*> as,

Step 2

1)

The photon given in the problem is vertically polarized,

Therefore the probability amplitude for the photon to pass through the first polarizer is given by

Step 3

Since states |*x*> and | *y*> are assumed to b...
