A Quantum Turnstile Chip for Photons ⚡ экспресс
Original: "Quantum-coherent optical isolation and circulation using frequency conversion on a chip"
Physicists have created a microchip turnstile for light particles: it strictly allows passage in one direction, without destroying their quantum nature.

Scientists have created a microchip that works as a turnstile for light particles: it lets them through in one direction only and preserves quantum purity. This is a step toward an interference-resistant quantum internet.
🎯 Ordinary prisms and lenses, like in binoculars, only change the direction of light but don't prevent backward travel. This chip is a true non-return valve for photons.
