At the threshold where classical and quantum physics have long stood apart, a team of researchers has found a passage between them — demonstrating that ordinary light, shaped by the right conditions, can be made to think in quantum terms. The discovery, emerging from controlled laboratory work in 2026, suggests that the hard boundary separating the everyday world from the subatomic one may be more a matter of engineering than of nature. If light itself can become a quantum processor, then the long-promised era of practical quantum computing may arrive not through exotic new materials, but thro
