c)

After 100 experiments on each source, 52 of the photons from tex2html_wrap_inline336 pass through the r filter and 99 of the photons from tex2html_wrap_inline338 pass through the r filter. Are A and B the same quantum state? Is A a pure state with respect to r? With respect to x? Is B a pure state with respect to r? With respect to x?
