Superradiance as a Source of Collective Decoherence in Quantum Computers
arXiv:1407.0411 · doi:10.1364/JOSAB.31.002665
Abstract
We argue that superradiance (collective emission) due to radiative coupling of qubit states results in non-local noise, and thus introduces an error source that cannot be corrected using current models of fault-tolerant quantum computation.
