SUMMARY
In quantum entanglement, when two photons are entangled, measuring the spin of one photon directly determines the spin of the other. However, once one of the particles is measured, it does not retain its entanglement. Consequently, repeated measurements on photon A will not yield additional information about photon B's spin, as each particle can only be measured once in this context.
