Single-shot measurements of phonon number states using the Autler-Townes effect
Marion Mallweger, Murilo Henrique de Oliveira, Robin Thomm +6
We present a single-shot method to measure motional states in the number basis. The technique can be applied to systems with at least three non-degenerate energy levels which can b…
High-Q magnetic levitation and control of superconducting microspheres at millikelvin temperatures
Joachim Hofer, Rudolf Gross, Gerard Higgins +11
We report the levitation of a superconducting lead-tin sphere with 100 micrometer diameter (corresponding to a mass of 5.6 micrograms) in a static magnetic trap formed by two coils…
Superconducting microsphere magnetically levitated in an anharmonic potential with integrated magnetic readout
Martí Gutierrez Latorre, Gerard Higgins, Achintya Paradkar +2
Magnetically levitated superconducting microparticles offer a promising path to quantum experiments with picogram to microgram objects. In this work, we levitate a 700ng $\sim 10^{…
Steady-state entanglement generation for non-degenerate qubits
Murilo H. Oliveira, Gerard Higgins, Chi Zhang +4
We propose a scheme to dissipatively produce steady-state entanglement in a two-qubit system, via an interaction with a bosonic mode. The system is driven into a stationary entangl…
Non-Hermitian dynamics and -symmetry breaking in interacting mesoscopic Rydberg platforms
José A. S. Lourenço, Gerard Higgins, Chi Zhang +2
We simulate the dissipative dynamics of a mesoscopic system of long-range interacting particles which can be mapped into non-Hermitian spin models with a symmetry. W…
A chip-based superconducting magnetic trap for levitating superconducting microparticles
Martí Gutierrez Latorre, Achintya Paradkar, David Hambraeus +2
Magnetically-levitated superconducting microparticles have been recently proposed as a promising platform for performing quantum experiments with particles in the picogram regime.…
