On Quantum Fidelities and Channel Capacities
H. Barnum, E. Knill, M. A. Nielsen
We show the equivalence of two different notions of quantum channel capacity: that which uses the entanglement fidelity as its criterion of success in transmission, and that which…

Dynamical Decoupling of Open Quantum Systems
Lorenza Viola, Emanuel Knill, Seth Lloyd
We propose a novel dynamical method for beating decoherence and dissipation in open quantum systems. We demonstrate the possibility of filtering out the effects of unwanted (not ne…

On the Power of One Bit of Quantum Information
E. Knill, R. Laflamme
In standard quantum computation, the initial state is pure and the answer is determined by making a measurement of some of the bits in the computational basis. What can be accompli…
