Why does the read operation only break entanglement in 50% of the cases?

Why does the read operation only break entanglement in 50% of the cases?
- Ralfp 4y agoIt doesn't. B is guaranteed to be !A and A is guaranteed to be !B. Changing either breaks the entaglement. Also because in order to see what state is particle we need to interact with it, measuring its quantum state also breaks the entaglement.
- k__ 4y agoAh, I misread it. The action that breaks the entanglement is the update of A before reading B and not the reading of A or B.
