Suppose that an unpolarized beam of photons interacts with a PBS with its “horizontal” direction set at 0°0\degree. The hlp\text{hlp} output beam from the PBS continues on and then interacts with a PBS whose “horizontal” direction is set at 90°90\degree. What will be the output from the second PBS?

A)

All photons will exit the second PBS.

B)

Half of the photons will exit the second PBS.

C)

A quarter of the photons will exit the second PBS.

D)

No photons will exit the second PBS.
