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…
Overcoming intrinsic material limitations through cavity feedback
M. Ebrahimi, Y. Huang, V. A. S. V. Bittencourt +3
Magnons, the quanta of spin waves, have significant potential for use in modern technologies, especially when strongly coupled to another mode for read-out and control. However, wh…
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.…
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…
Quantum tomography of magnons using Brillouin light scattering
Sanchar Sharma, Silvia Viola Kusminskiy, Victor A. S. V. Bittencourt
Quantum magnonics, an emerging field focusing on the study of magnons for quantum applications, requires precise measurement methods capable of resolving single magnons. Existing t…
