1. Scalability: Spin qubits can be integrated into existing semiconductor fabrication processes, making it easier to scale up the number of qubits. 2. Long Coherence Times: Spin qubits, especially those in silicon, can maintain their quantum states for relatively long periods, which is critical for performing computations. 3. Compactness: The small size of spin qubits allows for the creation of densely packed quantum circuits. 4. Compatibility: Spin qubits can be fabricated using standard silicon-based technologies, making them easier to integrate with current electronic devices.
