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…
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.…
Quantum-impurity sensing of altermagnetic order
V. A. S. V. Bittencourt, Hossein Hosseinabadi, Jairo Sinova +2
Quantum sensing with individual spin defects has emerged as a versatile platform to probe microscopic properties of condensed matter systems. Here we demonstrate that quantum relax…
Photonic crystal cavities based on suspended yttrium iron garnet nanobeams
Alireza Rashedi, Mehri Ebrahimi, Yunhu Huang +3
We report the fabrication and optical characterization of an air-suspended photonic crystal nanobeam cavity in yttrium-iron-garnet (YIG) realized by focused-ion-beam milling. YIG's…
