Two Quantum Algorithms for Communication between Spacelike Separated Locations

A. Datta·Sep 16, 2022

The `no communication' theorem prohibits superluminal communication by showing that any measurement by Alice on an entangled system cannot change the reduced density matrix of Bob's state, and hence the expectation value of any measurement operator t...
