Stroboscopic detection of itinerant microwave photons
Hanna Zeller, Lukas Danner, Max Hofheinz +4
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…
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…
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…
