Why are superconducting qubits preferred for early quantum processors?

Example Concept: Superconducting qubits leverage Josephson junctions to create anharmonic energy levels, enabling the definition of qubit states. Their coherence times, while limited by noise and decoherence, are sufficient for executing quantum algorithms when combined with error correction techniques. The ability to fabricate these qubits using established lithographic processes allows for rapid prototyping and scaling, which is crucial for advancing quantum processor development.
