Optimal Encoding of Classical Information in a Quantum Medium
Noam Elron, Yonina C. Eldar
We investigate optimal encoding and retrieval of digital data, when the storage/communication medium is described by quantum mechanics. We assume an m-ary alphabet with arbitrary p…

Quantum Detection with Unknown States
Noam Elron, Yonina C. Eldar
We address the problem of distinguishing among a finite collection of quantum states, when the states are not entirely known. For completely specified states, necessary and suffici…
