Introduction to Quantum Information Processing
E. Knill, R. Laflamme, H. Barnum +7
As a result of the capabilities of quantum information, the science of quantum information processing is now a prospering, interdisciplinary field focused on better understanding t…
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…
Threshold Accuracy for Quantum Computation
E. Knill, R. Laflamme, W. Zurek
We have previously (quant-ph/9608012) shown that for quantum memories and quantum communication, a state can be transmitted over arbitrary distances with error provided each ga…
A Theory of Quantum Error-Correcting Codes
Emanuel Knill, Raymond Laflamme
Quantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a gener…
Decoherence Bounds on Quantum Computation with Trapped Ions
Richard J. Hughes, Daniel F. V. James, Emanuel H. Knill +2
Using simple physical arguments we investigate the capabilities of a quantum computer based on cold trapped ions. From the limitations imposed on such a device by spontaneous decay…
Decoherence, Re-coherence, and the Black Hole Information Paradox
J. R. Anglin, R. Laflamme, W. H. Zurek +1
We analyze a system consisting of an oscillator coupled to a field. With the field traced out as an environment, the oscillator loses coherence on a very short {\it decoherence tim…
