Decoherence-free
Webdecoherence-free subspaces may appear without spatial symmetry. Instead, we consider a model of system-bath interactions in which to first order only multiple-qubit coupling to the bath is present, with single-qubit system-bath coupling absent. We derive necessary and sufficient conditions for the appearance of decoherence-

We consider the case where the parameters, such as mass, frequency, and the damping coefficient, vary with time. The invariant operator theory is employed in order to describe quantum evolution of the system. It is supposed that the …

WebMar 25, 2016 · Formally, an open system is decoherence free if its evolution is unitary, despite non-vanishing couplings to its environment. Information encoded in system states that evolve in such unitary fashion is immune to decoherent environmental effects, although the latter are by no means suppressed.
