GHZ entanglement

Quote Quote by StevieTNZ View Post
If we have the GHZ state: |V>|H>|H>|V> + |H>|V>|V>|H>, if photons 1 and 4 take on polarisation 135, do photons 2 and 3 take on the opposite - 45 polarisation?
To find the answer to this, all you need to do is write |H> and |V| in terms of |45> and |135>.
