On communication over an entanglement-assisted quantum channel [article]

Ashwin Nayak
2002 arXiv   pre-print
Shared entanglement is a resource available to parties communicating over a quantum channel, much akin to public coins in classical communication protocols.  ...  In contrast, our result is derived from first principles, using a simple linear algebraic technique.  ...  Remarkably, it has been shown that if the two parties are equipped with a quantum computer and can communicate by exchanging quantum states, they can solve certain tasks at a significantly smaller communication  ...
