Two-resonator circuit QED: A superconducting quantum switch
Matteo Mariantoni, Frank Deppe, A. Marx +3
We introduce a systematic formalism for two-resonator circuit QED, where two on-chip microwave resonators are simultaneously coupled to one superconducting qubit. Within this frame…
Quantum Zeno Effect in the Quantum Non-Demolition Detection of Itinerant Photons
Ferdinand Helmer, Matteo Mariantoni, Enrique Solano +1
We analyze the detection of itinerant photons using a quantum non-demolition (QND) measurement. We show that the backaction due to the continuous measurement imposes a limit on the…
Two-dimensional cavity grid for scalable quantum computation with superconducting circuits
Ferdinand Helmer, Matteo Mariantoni, Austin G. Fowler +3
Superconducting circuits are among the leading contenders for quantum information processing. This promising avenue has been strengthened with the advent of circuit quantum electro…
Orthogonally-Driven Superconducting Qubit in Circuit QED
M. J. Storcz, M. Mariantoni, H. Christ +6
We consider a superconducting charge qubit coupled to distinct orthogonal electromagnetic field modes belonging to a coplanar wave guide and a microstrip transmission line resonato…
