Decoherence-free subspaces for a quantum register interacting with a spin environment
Open Syst. Inf. Dyn. 20, 1350014 (2013) We study a model of a quantum spin register interacting with an environment of spin particles in quantum-measurement limit. In the limit of collective decoherence we obtain the form of state vectors that constitute high-dimensional decoherence-free subspaces (...

| description | Open Syst. Inf. Dyn. 20, 1350014 (2013) We study a model of a quantum spin register interacting with an environment
of spin particles in quantum-measurement limit. In the limit of collective
decoherence we obtain the form of state vectors that constitute
high-dimensional decoherence-free subspaces (DFS). In a more general setting we
present sufficient and necessary conditions for existence of low-dimensional
DFSs that can be used to construct subspaces of higher dimension. |
