Quantum source-channel coding and non-commutative graph theory
Dan Stahlke
Alice and Bob receive a bipartite state (possibly entangled) from some finite collection or from some subspace. Alice sends a message to Bob through a noisy quantum channel such th…
Bounds on entanglement assisted source-channel coding via the Lovasz theta number and its variants
Toby Cubitt, Laura Mancinska, David Roberson +3
We study zero-error entanglement assisted source-channel coding (communication in the presence of side information). Adapting a technique of Beigi, we show that such coding require…
Quantum interference as a resource for quantum speedup
Dan Stahlke
Quantum states can in a sense be thought of as generalizations of classical probability distributions, but are more powerful than probability distributions when used for computatio…
Entanglement requirements for implementing bipartite unitary operations
Dan Stahlke, Robert B. Griffiths
We prove, using a new method based on map-state duality, lower bounds on entanglement resources needed to deterministically implement a bipartite unitary using separable (SEP) oper…
