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…
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…
Limitation of entanglement due to spatial qubit separation
Roland Doll, Martijn Wubs, Peter Hanggi +1
We consider spatially separated qubits coupled to a thermal bosonic field that causes pure dephasing. Our focus is on the entanglement of two Bell states which for vanishing separa…
