Qubit dephasing due to Quasiparticle Tunneling
Sebastian Zanker, Michael Marthaler
We study dephasing of a superconducting qubit due to quasiparticle tunneling through a Josephson junction. While qubit decay due to tunneling processes is well understood within a…
Synthesizing Lattice Structure in Phase Space
Lingzhen Guo, Michael Marthaler
We consider a realistic model, i.e., ultracold atoms in a driven optical lattice, to realize phase space crystals [Phys. Rev. Lett. 111, 205303 (2013)]. The corresponding lattice s…
Multi-photon dressing of an anharmonic superconducting many-level quantum circuit
Jochen Braumüller, Joel Cramer, Steffen Schlör +10
We report on the investigation of a superconducting anharmonic multi-level circuit that is coupled to a harmonic readout resonator. We observe multi-photon transitions via virtual…
Electroluminescence and multi-photon effects in a resonator driven by a tunnel junction
Jinshuang Jin, Michael Marthaler, Gerd Schön
We consider a transmission line resonator which is driven by electrons tunneling through a voltage-biased tunnel junction. Using the Born-Markovian quantum master equation in the p…
Circular-polarization sensitive metamaterial based on triple quantum-dot molecules
Panagiotis Kotetes, Pei-Qing Jin, Michael Marthaler +1
We propose a new type of a chiral metamaterial based on an ensemble of artificial molecules formed by three identical quantum-dots in a triangular arrangement. A static magnetic fi…
Time local master equation connecting the Born and Markov approximations
Christian Karlewski, Michael Marthaler
We present an exact expansion of the master equation for an open quantum system. The resulting equation is time local and enables us to calculate clearly defined higher order corre…
