Quantum MacWilliams Identities
Peter Shor, Raymond Laflamme
We derive a relationship between two different notions of fidelity (entanglement fidelity and average fidelity) for a completely depolarizing quantum channel. This relationship giv…
Concatenated Quantum Codes
Emanuel Knill, Raymond Laflamme
One of the main problems for the future of practical quantum computing is to stabilize the computation against unwanted interactions with the environment and imperfections in the a…
Perfect Quantum Error Correction Code
Raymond Laflamme, Cesar Miquel, Juan Pablo Paz +1
We present a quantum error correction code which protects a qubit of information against general one qubit errors which maybe caused by the interaction with the environment. To acc…
Effects of Loss and Decoherence on a Simple Quantum Computer
Isaac L. Chuang, Raymond Laflamme, Juan-Pablo Paz
We investigate the impact of loss (amplitude damping) and decoherence (phase damping) on the performance of a simple quantum computer which solves the one-bit Deutsch problem. The…
