Superconducting quantum computers dominate current development, but integrated photonics offers an alternative that uses photons instead of electrons for quantum information processing. Photonic qubits operate at room temperature rather than near absolute zero, maintain quantum properties longer, and resist environmental interference better than superconducting approaches. The technology applies established semiconductor manufacturing to build quantum circuits on silicon chips, addressing key challenges in scaling to millions of qubits, integrating components on single devices, ensuring reliable operations, and creating commercially viable systems. This approach suits applications where operational consistency takes precedence over raw computational speed.

Integrated photonics enhances quantum computing with photonic qubits, offering improved stability and scalability through established semiconductor techniques.
