Streaming Communication Protocols [PDF]

open access: yesACM Transactions on Computation Theory, 2018
We define the Streaming Communication model that combines the main aspects of communication complexity and streaming. Input arrives as a stream, spread between several agents across a network. Each agent has a bounded memory, which can be updated upon receiving a new bit, or a message from another agent. We provide tight tradeoffs between the necessary

Inefficiency and classical communication bounds for conversion between partially entangled pure bipartite states

open access: yes, 2005
We derive lower limits on the inefficiency and classical communication costs of dilution between two-term bipartite pure states that are partially entangled.

Secret key expansion from covert communication

open access: yes, 2017
Covert communication allows us to transmit messages in such a way that it is not possible to detect that the communication is occurring. This provides protection in situations where knowledge that people are talking to each other may be incriminating to ...
