In this question v) and |h) are photon states of vertical and horizontal polarization relative to the z-axis, while v) and |h) are states of vertical and horizontal polarization relative to the -axis the axes are such that hv) 2 viv) and hh (vh) 2 we consider the entangled two-photon state ja) vv)hh))=(v)v2+ |h),|h)2)| where the subscripts 1 and 2 in the right-hand expression refer to photons 1and 2 (a) if the polarizations of the two photons are both measured relative to the -axis, calculate the probability that both photons give vertical polarizations (b) if the polarization of photon 1 is measured relative to the z-axis and the polarization of photon 2 is measured relative to the -axis, calculate the probability that both photons will give vertical polarizations
