The idea of quantum teleportation was proposed by Charles Bennett and realized by Anton Zeilinger. It uses entanglement — when two particles are in sync, like two sheets of paper that instantly copy the same drawing. But earlier, the "ink" would blur, ruining the blueprint. Now physicists used light with a special ripple (non-Gaussian states) that doesn’t smudge the lines. The copy’s accuracy is 97.3%. And here’s a surprise: the original disappears in the process, as if the sheet becomes blank after sending the blueprint.
A fast controller selects successful events, and the data goes to measurements. This paves the way for quantum repeaters that stretch connections over thousands of kilometers, and for powerful quantum computers.
Quantum teleportation transfers information, not matter: the original particle turns into a blank page, while an exact copy appears at the receiver.
In 'Star Trek', people vanish and reappear elsewhere, but in reality, quantum teleportation only carries the weightless blueprints of particles, while the original is destroyed.
