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.

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 9, 2004 · Decoherence-free states protect quantum information from collective noise, the predominant cause of decoherence in current implementations of quantum communication and computation.
