Noisy Quantum Computation and Communication
Mary Beth Ruskai · 2003
When quantum particles are used to transmit information, one can expect that, as with classical communication, noise in the channel will affect the fidelity of the transmission. This is true whether the particles are used to transmit quantum or classical information. Similar concerns arise in quantum computation when the noise due to interactions with the environment gives rise to errors. This project has been concerned with the analysis of noise that breaks entanglement and with the development of new codes for quantum error correction.
