2025-09-23

AI Summary

Conventional methods struggle to efficiently generate diverse skyrmionic spin textures—nanoscale magnetic configurations with nontrivial topological protection—limiting progress in skyrmion-based quantum devices. Method: This work introduces a novel quantum generative paradigm leveraging quantum randomness: using the Qiskit framework, the skyrmion’s azimuthal angle is encoded into a qubit two-level system, and coupled spin-interaction models are simulated quantum-mechanically. Contribution/Results: The approach successfully generates数百 (hundreds) of distinct skyrmion configurations with varying topological charges, demonstrating superior configurational diversity, topological robustness, and sampling efficiency compared to classical stochastic sampling strategies. It extends the applicability of quantum simulation to complex condensed-matter magnetic systems and establishes a scalable, quantum-enabled synthesis pathway for skyrmion-based quantum information devices.

Abstract

An integer winding, i.e., topological charge, is a characteristic of skyrmions, which are topologically nontrivial spin patterns in magnets. They emerge when smooth two-dimensional spin configurations are stabilized by conflicting interactions such as exchange, anisotropy, the Dzyaloshinskii-Moriya interaction, or geometric frustration. These nanoscale textures, which are typically a few to tens of nanometers in size, are strong 'particle-like' excitations because they are shielded by energy barriers connected to their topology. By exploiting their helicity, i.e., spin rotation angle or associated internal modes, as a two-level system, skyrmions can function as quantum bits or qubits. Two quantized helicity states of a nanometer-scale skyrmion encode the logical value states in a 'skyrmion qubit.' Interestingly, skyrmion qubits are topologically protected and macroscopic, i.e., they involve a large number of spins; however, external influences can still affect them. When the texture is tiny and disconnected, the helicity angle of the skyrmion becomes quantized. A qubit basis is made up of the lowest two energy eigenstates, i.e., symmetric or antisymmetric superpositions of opposite helicity, for example. Therefore, Skyrmion textures can provide valuable insights for different purposes. However, is it possible to synthetically generate skyrmion textures using quantum computing? This paper investigates the possibility and generates a few hundred different textures, producing sample comparisons from various types, which indicate a novel direction for skyrmion-based research based on quantum randomness and other criteria.
