Photons are prepared in a vertical state (90º), split in a crystal and sent to Bob and Alice. Both Bob and Alice will measure 100% vertical and 0% horizontal.
Photons are prepared in a 45º state, split in a crystal and sent to Bob and Alice. Both Bob and Alice will measure 50% vertical and 50% horizontal. This can be calculated by applying a matrix to the Jones vector. Are these photons entangled and are Bob and Alice guaranteed the same reading for each photon? Is simply splitting the photon enough to cause entanglement or is a more complex process needed to ensure entanglement?
