Silicon hole spins are promising candidates for realizing qubits as they enable fast spin manipulation without additional structures. In this research, we demonstrate coherent control of a hole spin in a quantum dot fabricated using fully depleted silicon-on-insulator (FDSOI), which is beneficial for scaling to large-scale qubits, and self-aligned technology that enables the formation of finer gates. These results confirm the potential of hole spin qubits in this structure.
