  Selective control of individual spin qubits is needed for scalable quantum
computing based on spin states. Achieving high-fidelity in both single and
two-qubit gates, essential components of universal quantum computers,
necessitates highly localized control fields. These fields must be capable of
addressing specific spin qubits while minimizing gate errors and cross-talk in
adjacent qubits. Overcoming the challenge of generating a localized
radio-frequency magnetic field, in the absence of elementary magnetic
monopoles, we introduce a technique that combines divergent and convergent
nanoscale magnetic skyrmions. This approach produces a precise control field
that manipulates spin qubits with high fidelity. We propose the use of 2D
skyrmions, which are 2D analogues of 3D hedgehog structures. The latter are
emergent magnetic monopoles, but difficult to fabricate. The 2D skyrmions, on
the other hand, can be fabricated using standard semiconductor foundry
processes. Our comparative analysis of the density matrix evolution and gate
fidelities in scenarios involving proximal skyrmions and nanomagnets indicates
potential gate fidelities surpassing 99.95% for {\pi}/2-gates and 99.90% for
{\pi}-gates. Notably, the skyrmion configuration generates a significantly
lower field on neighboring spin qubits, i.e. 15 times smaller field on a
neighboring qubit compared to nanomagnets that produces the same field at the
controlled qubit, making it a more suitable candidate for scalable quantum
control architectures by reducing disturbances in adjacent qubits.
