Three Myths about Time Reversal in Quantum Theory
... supposing time reversal does more than reverse the order of states in a trajectory. The standard expression of time reversal maps a trajectory w(t) to Tw(2t), reversing the order of a trajectory t ↦ 2t but also transforming instantaneous states by the operator T. Both Callender and Albert propose th ...

Towards a Tight Finite Key Analysis for BB84
... either X or Z, chosen at random. The X bits will be used to extract a key, while the Z are used to check security. She sends the qubit over a public channel to Bob, while the eavesdropper, Eve, may interfere as she wishes. Bob measures the system randomly either in the X or Z basis. Alice and Bob si ...
