Abstract

This paper proposes using a nanoscale meron in a magnetic nanodisk as a qubit, where the up and down directions of the core spin represent the qubit states |0⟩ and |1⟩. The authors numerically demonstrate the stabilization of a meron with a radius containing as few as 7 spins in a ferromagnetic nanodisk. They theoretically show that universal quantum computation is achievable using merons by constructing arbitrary phase-shift, Hadamard, and CNOT gates, controlled via magnetic fields or spin-polarized currents. The paper's findings suggest a potential pathway for implementing quantum computation using topological spin textures in nanomagnets.
