Fidelity and Entanglement of a Spatially Extended Linear Three-Qubit Register
Roland Doll, Martijn Wubs, Sigmund Kohler +1
We study decoherence of a three-qubit array coupled to substrate phonons. Assuming an initial three-qubit entangled state that would be decoherence-free for identical qubit positio…

On the conundrum of deriving exact solutions from approximate master equations
Roland Doll, David Zueco, Martijn Wubs +2
We derive the exact time-evolution for a general quantum system under the influence of pure phase-noise and demonstrate that for a Gaussian initial state of the bath, the exact res…

Incomplete pure dephasing of N-qubit entangled W states
Roland Doll, Martijn Wubs, Peter Hanggi +1
We consider qubits in a linear arrangement coupled to a bosonic field which acts as a quantum heat bath and causes decoherence. By taking the spatial separation of the qubits expli…
