Non-dissipative decoherence bounds on quantum computation
arXiv:quant-ph/0012057 · doi:10.1103/PhysRevA.63.032310
Abstract
We investigate the capabilities of a quantum computer based on cold trapped ions in presence of non-dissipative decoherence. The latter is accounted by using the evolution time as a random variable and then averaging on a properly defined probability distribution. Severe bounds on computational performances are found.
