Microtraps for neutral atoms using superconducting structures in the critical state
Andreas Emmert, Adrian Lupascu, Michel Brune +3
Recently demonstrated superconducting atom-chips provide a platform for trapping atoms and coupling them to solid-state quantum systems. Controlling these devices requires a full u…
Effect of vortices on the spin-flip lifetime of atoms in superconducting atom-chips
Gilles Nogues, Cédric Roux, Thomas Nirrengarten +7
We study theoretically the lifetime of magnetically trapped atoms in the close vicinity of a type-II superconducting surface, in the context of superconducting atom-chips. We accou…
Quantum feedback by discrete quantum non-demolition measurements: towards on-demand generation of photon-number states
I. Dotsenko, M. Mirrahimi, M. Brune +3
We propose a quantum feedback scheme for the preparation and protection of photon number states of light trapped in a high-Q microwave cavity. A quantum non-demolition measurement…
Measurement of the trapping lifetime close to a cold metallic surface on a cryogenic atom-chip
Andreas Emmert, Adrian Lupascu, Gilles Nogues +3
We have measured the trapping lifetime of magnetically trapped atoms in a cryogenic atom-chip experiment. An ultracold atomic cloud is kept at a fixed distance from a thin gold lay…
High-resolution spatial mapping of a superconducting NbN wire using single-electron detection
A. Lupascu, A. Emmert, M. Brune +5
Superconducting NbN wires have recently received attention as detectors for visible and infrared photons. We present experiments in which we use a NbN wire for high-efficiency (40…
