Wasn't sure whether to post this in SR or QP here, but chose the latter.(adsbygoogle = window.adsbygoogle || []).push({});

Assuming:

1. The results of a quantum measurement are random, and that Alice and Bob (performing simultaneous measurements on widely separated, entangled particles) end up with measurements that are perfectly correlated.

2. This would be a way of exchanging (i.e., agreeing on) encryption keys, in that both Alice and Bob would measure the same bit stream. (If so, would one pair of entangled particles be sufficient, or would they need a unique pair per key bit?)

3. Alice and Bob travel away from each other at a relative velocity of .866c for a Lorentz factor of 2, each taking one measurement per minute by their own clock (two by the other's).

Question: Are their measurements still correlated? In other words, do they arrive at the same key?
