As an example of using these sideband transitions for a two-qubit operation, we implement a pulse sequence that first entangles one qubit with the resonator and subsequently distributes the entanglement between two qubits. We show the generation of 75% fidelity Bell states by this method. The full density matrix of the two-qubit system is extracted using joint measurement and quantum state tomography and shows close agreement with numerical simulation."}],"author":[{"last_name":"Leek","first_name":"Peter","full_name":"Leek, Peter J"},{"full_name":"Filipp, Stefan","first_name":"Stefan","last_name":"Filipp"},{"full_name":"Maurer, Patrick","last_name":"Maurer","first_name":"Patrick"},{"first_name":"Matthias","last_name":"Baur","full_name":"Baur, Matthias P"},{"full_name":"Bianchetti, R","first_name":"R","last_name":"Bianchetti"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Johannes Fink","last_name":"Fink","orcid":"0000-0001-8112-028X","first_name":"Johannes M"},{"full_name":"Göppl, M","first_name":"M","last_name":"Göppl"},{"first_name":"L.","last_name":"Steffen","full_name":"Steffen, L.
