Multiple System-Decomposition Method for Avoiding Quantum Decoherence
-
Abstract
Decomposition of a composite system C into different subsystems, A + B or
D + E, may help in avoiding decoherence. For example, the environment-induced decoherence for an A + B system need not destroy entanglement present in the D + E system (A + B = C = D + E). This new approach opens some questions also in the foundations of the quantum computation theory that might eventually lead to a new model of quantum computation.
