Probabilistic generation of two-mode binomial cat states using cross-Kerr interactions
S. Zhao, A. Metelmann, S. Qvarfort
Superpositions of macroscopically distinct coherent states, or cat states, are a key resource for quantum technologies. In particular, two-mode binomial cat states can give rise to…
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…
Double-Pumped Kerr Parametric Amplifier Beyond the Gain-Bandwidth Limit
Nicolas Zapata, Najmeh Etehadi Abari, Mitchell Field +5
Superconducting standingwave parametric amplifiers are crucial for the readout of microwave quantum devices. Despite significant improvements in recent years, the need to operat…
