Photonic powerhouse: Light is driving the quantum revolution

By Eric Mounier for Laser Focus World – Photonics enables qubit platforms to function and scale toward practical machines—and demand for specialized lasers will grow as quantum computing scales.

Photonics and lasers lie at the heart of the quantum computing revolution. They are indispensable tools that enable many of the most promising qubit platforms to function and scale toward practical machines that can tackle real-world problems. Building a useful quantum computer remains a monumental task. Engineers and physicists must contend with qubit noise, error-correction overhead, and the persistent challenge of scaling. Unlike classical bits, fragile quantum states can be disturbed by the slightest perturbations. As a result, researchers strive to maintain high fidelity and long coherence time, because most error-correcting methods demand two-qubit gate fidelities much above 99.9% to achieve fault tolerance.

At Yole Group, we’re closely monitoring and analyzing the evolution of quantum technologies. Our in-depth analyses, including the Quantum Technologies 2025 and Optical Computing 2024 reports, provide a clear understanding of this rapidly advancing field. Where does the technology stand today? What influence will quantum technologies exert on the photonics landscape? What are the most promising applications and who are the key players shaping this ecosystem?
