Stroboscopic detection of itinerant microwave photons
Hanna Zeller, Lukas Danner, Max Hofheinz +3
We present a novel scheme to detect itinerant microwave radiation at the single photon level. Using existing Josephson-photonics devices, where two microwave cavities are coupled b…
Optomechanical Cooling without Residual Heating
Surangana Sengupta, Björn Kubala, Joachim Ankerhold +1
Resolved-sideband cooling is a standard technique in cavity optomechanics enabling quantum control of mechanical motion, but its performance is ultimately limited by quantum backac…
Quantum Coherence in Superconducting Vortex States
Ameya Nambisan, Simon Günzler, Dennis Rieger +13
Abrikosov vortices, where the superconducting gap is completely suppressed in the core, are dissipative, semi-classical entities that impact applications from high-current-density…
Fast initialization of Bell states with Schrödinger cats in multi-mode systems
Miriam Resch, Ciprian Padurariu, Björn Kubala +1
Schrödinger cat states play an important role for applications in continuous variable quantum information technologies. As macroscopic superpositions they are inherently protected…
Josephson junction cavity systems as cousins of the quantum optical micromaser
Simon Dambach, Andrew D. Armour, Björn Kubala +1
We explore the similarities and differences between simple theoretical models developed to describe the quantum optical micromaser and Josephson-photonics devices. Whilst the micro…
Non-equilibrium dynamics of the Dicke model for mesoscopic aggregates: signatures of superradiance
Sebastian Fuchs, Joachim Ankerhold, Miles Blencowe +1
In the dissipative quantum dynamics of a mesoscopic aggregate of excited two level systems (atoms) coupled to a single resonance mode of a cavity, two physical phenomena associated…
