Quantum Entanglement Helps Play Pong ⚡ экспресс
Quantum entanglement connects particles like synchronized clocks: they change in lockstep. Can it help in competitive games like Pong? An experiment found that a quantum player with entanglement learns faster and wins more often. It's like it sees not just the ball, but the whole game at once.
In ping-pong, two paddles connected by an invisible thread feel each other's movements, guessing the ball's trajectory. Researchers gave a computer a similar thread — quantum entanglement. Into an ordinary trial-and-error learning program, they embedded a quantum circuit of eight qubits — particles that can spin like a coin on its edge. When they become entangled (John Stewart Bell showed the weirdness of this effect), they turn into one whole: push one, and all respond. This circuit served as the algorithm's "eyes," turning screen pixels into interpretable signals.
The thread's tension was tweaked on the fly during the game, strengthening the bond. And the entangled player beat regular neural networks, especially when resources were scarce. It discerned hidden patterns in the opponent's moves, imperceptible to simple programs. The thread vibrated, transmitting information faster than any gravitational waves, and its pull gathered qubits together like a miniature black hole. It's astonishing that such a connection required cooling the chip to near absolute zero — a temperature lower than interstellar space.
🎯 To entangle qubits in the lab, chips are often cooled to near absolute zero — colder than outer space.
🎬 This work brings to mind the idea from the novel Ender's Game, where an AI learns by analyzing human behavior in strategy games.
