Chiral magnons for spin-qubit state transfer
Martijn Dols, Carlos Gonzalez-Ballestero, Mikhail Cherkasskii +3
We propose a protocol where chiral magnons mediate a state transfer between two distant spin qubits. The protocol is implemented by varying the coupling between the spin qubits and…
Remote entanglement of massive oscillators via wire-mediated Coulomb interaction
Lorenzo Papa, Onur Hosten, Carlos Gonzalez-Ballestero
The paper proposes using a nearby conducting wire to enhance the Coulomb interaction between charged macroscopic mechanical oscillators, enabling steady‑state motional entanglement…
Steady-state entanglement of spin qubits mediated by nonreciprocal and chiral magnons
Martijn Dols, Mikhail Cherkasskii, Victor A. S. V. Bittencourt +3
We propose a hybrid quantum system in which a magnet supporting non-reciprocal magnons, chiral magnons, or both mediates the dissipative and unidirectional coupling of spin qubits.…
Engineering recoil heating in coherent-scattering levitated optomechanics
Maksim Lednev, UroÅ¡ DeliÄ, Johannes Feist +1
Recoil heating from photon scattering is a fundamental source of decoherence in optical trapping, severely limiting the preparation of nonclassical motional states. In cavity setup…
Classical and quantum theory of magnonic and magnetoelastic nonlinear dynamics in continuum geometries
Marco Brühlmann, Yunyoung Hwang, Jorge Puebla +1
We provide a theory of spin and acoustic wave coupled nonlinear dynamics in continuum systems. Combining the Landau-Lifshitz-Gilbert equations with the magnetoelastic Hamiltonian,…
Quantum State Preparation of Ferromagnetic Magnons by Parametric Driving
Monika E. Mycroft, Rostyslav O. Serha, Andrii V. Chumak +1
We propose a method to prepare and certify Gaussian quantum states of the ferromagnetic resonance spin-wave modes in ferromagnets using a longitudinal drive. Contrary to quantum op…
