Physicists found out: to open a wormhole, you have to shake it hard. Not literally — but on a quantum chip, they simulated a system of 8 particles, so chaotic and entangled that it turned into a vibrating hologram of a black hole. The theory of Susskind and Kitaev came to life in a real, though noisy, processor: the stronger the system's jitter, the clearer the tunnel emerges.
A signal was sent through this virtual funnel. It passed through, but came out with different intensity: the positive impulse passed differently than the negative one. Exactly how a real traversable wormhole would behave. The equipment's noise didn't erase the picture, but only confirmed it — for teleportation, internal shaking is exactly what's needed.
The main surprise: the same math describes any black hole as a holographic projector. All infalling information doesn't disappear, but is sort of recorded on its surface — like on a trembling film. Now physicists have a miniature proving ground for testing such ideas, which John Preskill dreamed of.
The idea that gravity can emerge from entanglement is called the holographic principle — as if our three-dimensional world is projected from a flat surface.
In Interstellar, the wormhole was meant for people, and here — for signals, but the principle is the same.
