Light under Control: One-Way Photons Without Magnets ⚡ экспресс
Original: "Quantum Interference Amplifies Weak Chirality into Giant Quantum Nonreciprocity"
Quantum interference turns a tiny rotation into a powerful one-way flow of light.

A resonator’s tiny spin barely changes how light behaves. But add quantum interference, and the effect is magnified thousands of times — suddenly, photons stream one way as loners, and flock together the other way. That’s how one-way quantum sources for future technologies are born.
🎯 The Fizeau effect, key to this method, allowed measurement of light’s speed in moving water in 1851 — a crucial step toward relativity.
🎬 One-way mirrors and force fields that let light pass only one way are a staple of sci-fi. This new work turns that exotic fiction into lab reality.
