Non-Dissipative Decoherence in Ion-Trap Quantum Computers
Stefano Mancini, Rodolfo Bonifacio · Kluwer Academic Publishers eBooks · 2006
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.
