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…
Passive quantum state transfer in a dispersion-engineered waveguide
Zeyu Kuang, Oliver Diekmann, Lorenz Fischer +2
High-fidelity state transfer is fundamentally limited by time-reversal symmetry: one qubit emits a photon with a certain temporal pulse shape, whereas a second qubit requires the t…
Collectively enhanced ground-state cooling in subwavelength atomic arrays
Oriol Rubies-Bigorda, Raphael Holzinger, Ana Asenjo-Garcia +6
Subwavelength atomic arrays feature strong light-induced dipole-dipole interactions, resulting in subradiant collective resonances characterized by narrowed linewidths. In this wor…
