Programming with Quantum Communication
This work develops a formal framework for specifying, implementing, and
analysing quantum communication protocols. We provide tools for developing
simple proofs and analysing programs which involve communication, both via
quantum channels and exhibiting the LOCC (local operations, classical
communication) paradigm
Programming Telepathy: Implementing Quantum Non-Locality Games
Quantum pseudo-telepathy is an intriguing phenomenon which results from the
application of quantum information theory to communication complexity. To
demonstrate this phenomenon researchers in the field of quantum communication
complexity devised a number of quantum non-locality games. The setting of these
games is as follows: the players are separated so that no communication between
them is possible and are given a certain computational task. When the players
have access to a quantum resource called entanglement, they can accomplish the
task: something that is impossible in a classical setting. To an observer who
is unfamiliar with the laws of quantum mechanics it seems that the players
employ some sort of telepathy; that is, they somehow exchange information
without sharing a communication channel. This paper provides a formal framework
for specifying, implementing, and analysing quantum non-locality games
