The Photonic Lathe: 100,000 Custom-Made Photons
Creating light with an exact number of photons is like stamping exactly 100,000 flawless coins. Until now, physicists could only control dozens of particles. The 'optical lathe' technology breaks this barrier: virtual lenses, like milling cutters, eliminate 'blurriness' and ensure each bunch contains exactly the specified number of photons. Counting becomes perfect.
