In regards to the attached image;
If the input photons were, for input b = photon #2, and for input c = photon #3, where:
photon #1 and #2, and #3 and #4 are entangled as |H>|V> + |V>|H>,
for the outputs:|H>(b’)|H>(b’) - |V>(b’)|V>(b’) + |H>(c’)|H>(c’) - |V>(c’)|V>(c’) + H(b’)|V>(c’) - |V>(b’)|H>(c’) (Not sure if I got the + and – signs correct?)
in the case of getting the outputs |H>(b’)|H>(b’) - |V>(b’)|V>(b’) + |H>(c’)|H>(c’) - |V>(c’)|V>(c’), would photons #2 and #3 be entangled with each other? Or would they remain entangled with their original partner?
So up until the actual detection of H(b’)|V>(c’) - |V>(b’)|H>(c’) (one specific bell-state) - or once that basis state is created when the photons entangle with the final detectors at the end output - the photons remain entangled with the original partner?
would the above be the same if photons #1 and #2, and #3 and #4 were entangled as |H>|V> - |V>|H>?
