Quantum privacy and quantum coherence
Benjamin Schumacher, Michael D. Westmoreland
We derive a simple relation between a quantum channel's capacity to convey coherent (quantum) information and its usefulness for quantum cryptography.
Information-theoretic approach to quantum error correction and reversible measurement
M. A. Nielsen, Carlton M. Caves, Benjamin Schumacher +1
Quantum operations provide a general description of the state changes allowed by quantum mechanics. The reversal of quantum operations is important for quantum error-correcting cod…
Information transmission through a noisy quantum channel
Howard Barnum, M. A. Nielsen, Benjamin Schumacher
Noisy quantum channels may be used in many information carrying applications. We show that different applications may result in different channel capacities. Upper bounds on severa…
