Entanglement dynamics under decoherence: from qubits to qudits
André R. R. Carvalho, Florian Mintert, Stefan Palzer +1
We investigate the time evolution of entanglement for bipartite systems of arbitrary dimensions under the influence of decoherence. For qubits, we determine the precise entanglemen…

Decoherence, pointer engineering and quantum state protection
A. R. R. Carvalho, P. Milman, R. L. de Matos Filho +1
We present a proposal for protecting states against decoherence, based on the engineering of pointer states. We apply this procedure to the vibrational motion of a trapped ion, and…
