LSU researchers have demonstrated a robust multiphoton quantum reservoir that operates at room temperature by extracting hidden quantum behavior from bright classical light rather than relying on fragile quantum sources. By utilizing photon-number-resolving detectors to access up to 40 photons, the system tolerates substantial noise and loss while simulating complex dynamics for information processing. This approach offers a practical pathway toward scalable quantum computing architectures that leverage existing optical infrastructure instead of requiring extreme isolation conditions.

Physicists turn classical light into a quantum machine for information processing

Phys.orgSeptember 12, 20266 min read

Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major obstacle: quantum systems are notoriously fragile. Noise, loss and even tiny disturbances can destroy the delicate behavior that gives them their power. Building systems with many quantum particles is also extremely challenging.

Different properties of light enter from the upper left and travel through an interconnected optical network. The network transforms the incoming light into a rich landscape of multiphoton patterns. Those patterns become a resource for information processing, allowing the system to learn and predict mathematical functions, illustrated by the curves along the bottom.
