We introduce a novel magnon-skyrmion hybrid quantum system. This system enables magnon-mediated nonreciprocal interactions for quantum information processing with magnetic microstructures.
Area of Science:
- Quantum physics
- Condensed matter physics
- Quantum information science
Background:
- Hybrid quantum systems require coherent and dissipative interactions between diverse quantum systems.
- Investigating novel quantum phenomena is crucial for advancing quantum technologies.
Purpose of the Study:
- To propose and analyze a novel magnon-skyrmion hybrid quantum system.
- To explore magnon-mediated nonreciprocal interactions for quantum information processing.
Main Methods:
- Theoretical analysis of a hybrid system comprising a micromagnet and magnetic skyrmions.
- Investigation of the coupling mechanism between magnonic modes and skyrmion helicity.
Main Results:
- Prediction of strong coupling between the micromagnet's magnonic mode and the skyrmion's quantized helicity.
- Demonstration of magnon-mediated nonreciprocal interactions between skyrmion qubits and other quantum systems (e.g., superconducting qubits).
Conclusions:
- The proposed magnon-skyrmion system offers a new quantum platform for exploring quantum effects.
- This hybrid system facilitates quantum information processing using magnetic microstructures.
