摘要: We review several approaches to define and quantify decoherence. find that a measure based on norm of deviation the density matrix is appropriate for quantifying decoherence quantum registers. For semiconductor double quantum-dot charge qubit, evaluation this presented. general class processes, including those occurring in qubits, we establish additive: It scales linearly with number qubits register.
