The exact cost of redistributing multipartite quantum states
Igor Devetak, Jon Yard
How correlated are two quantum systems from the perspective of a third? We answer this by providing an optimal quantum state redistribution protocol for multipartite product source…
Channel simulation with quantum side information
Zhicheng Luo, Igor Devetak
We study and solve the problem of classical channel simulation with quantum side information at the receiver. This is a generalization of both the classical reverse Shannon theorem…
Correcting Quantum Errors with Entanglement
Todd Brun, Igor Devetak, Min-Hsiu Hsieh
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require…
Catalytic quantum error correction
Todd Brun, Igor Devetak, Min-Hsiu Hsieh
We develop the theory of entanglement-assisted quantum error correcting (EAQEC) codes, a generalization of the stabilizer formalism to the setting in which the sender and receiver…
Efficiently implementable codes for quantum key expansion
Zhicheng Luo, Igor Devetak
The Shor-Preskill proof of the security of the BB84 quantum key distribution protocol relies on the theoretical existence of good classical error-correcting codes with the ``dual-c…
The mother of all protocols: Restructuring quantum information's family tree
Anura Abeyesinghe, Igor Devetak, Patrick Hayden +1
We give a simple, direct proof of the "mother" protocol of quantum information theory. In this new formulation, it is easy to see that the mother, or rather her generalization to t…
