Macroscopic Quantum Interference of the Center-of-Mass Motion of Levitated Superconducting Microparticles enabled by Magnetic Higher-Order Traps
Jaume Cunill-Subiranas, Fabian Resare, Suocheng Zhao +4
We show how magnetostatic higher-order multipole traps can be used to generate macroscopic quantum interference of the motion of levitated superconducting microparticles. An approp…
Dissipative preparation and stabilization of d-mode multinomial cat states
S. Zhao, A. Metelmann
Engineering dissipation with tailored steady states has become a powerful approach for preparing and stabilizing quantum states. In this framework, engineered dissipative processes…
Optics-microwave entanglement and state teleportation mediated by a cavity magnomechanical system
F. Engelhardt, A. V. Bondarenko, A. Metelmann +3
Generating usable output-entanglement in continuous variable systems can serve as a viable resource for improving applications in quantum information science. In this work, we show…
Qubit measurement and backaction in a multimode nonreciprocal system
B. T. Miller, Lindsay Orr, A. Metelmann +1
High fidelity qubit readout is a cornerstone for quantum information protocols. In traditional superconducting qubit readout, a chain of microwave amplifiers and nonreciprocal comp…
Self-Sustained Oscillations of a Nonlinear Optomechanical System in the Low-Excitation Regime
Shivangi Dhiman, K. Rubenbauer, T. Luschmann +3
Manifesting across all time, mass and length scales, nonlinearities lie at the core of numerous physical phenomena. Next-generation quantum applications, such as quantum sensing, r…
Optomechanical Backaction in the Bistable Regime
L. F. Deeg, D. Zoepfl, N. Diaz-Naufal +3
With a variety of realisations, optomechanics utilizes its light matter interaction to test fundamental physics. By coupling the phonons of a mechanical resonator to the photons in…
