Quantum Darwinism in a Composite System: Objectivity versus Classicality
We investigate the implications of quantum Darwinism in a composite quantum system with interacting constituents exhibiting a decoherence-free subspace. We consider a two-qubit system coupled to an <i>N</i>-qubit environment via a dephasing interaction. For excitation preserving interact...
