How a Beam of Light Turns into Schrödinger's Cat ⚡ экспресс
Original: "Towards Schr\"odinger Cat States in the Second Harmonic Generation"
A powerful laser beam inside a crystal spontaneously splits in two at the quantum level.

A beam of light can spontaneously become a “Schrödinger’s cat”—it splits into two phases, like a pendulum swinging left and right at once. It’s not a trick, but the result of quantum vacuum jitters during frequency doubling. Such macroscopic quantum states pave the way for new communication and measurement technologies.
🎯 The quantum vacuum isn’t empty: if you rapidly compress empty space, real photons will pop out—the dynamic Casimir effect.
\omega_{\rm blue} = 2\omega_{\rm red}
the frequency of blue light is twice that of red light
