Abstract: Talk is devoted to the discussion of decoherence phenomenon of a quantum system due to its interaction with the environment. Some criteria are formulated on the quantitative measure of decoherence in quantum information. A decoherence measure is proposed and examples of its application to qubits interacting with various systems are given. |
