BTW entanglement can be lost, there is a statistical probability of some pairs dis-entagling. Even after: vibration, temperature, mag/electro fields have been controlled. All comms has to have error correcting codes, therefore.

When I lived in Malvern I once asked John Rarity (an world expert on the subject) about it. His comment was quite succinct. "It's complicated".
