An unexpected bonus of quantum technologies: they can save energy, not just work faster. Scientists have shown that a photonic quantum chip uses less electricity per computational sample than the best classical algorithms, even though it lags in speed. The energy benefit becomes apparent before full computational supremacy.

🎯 The essence of the experiment is simulating light passing through a labyrinth of mirrors and beam splitters. For large setups, even the best supercomputers cannot predict the outcome, but the quantum chip does it naturally, "computing" by the laws of nature itself.

🎬 Sci-fi often portrays quantum computers as all-powerful. Reality adds a pleasant surprise: they also save energy.
