Quantum Telepathy Goes Real: How Lasers and Ions Outsmarted Logic

Physicists have successfully played a mind-bending “quantum game” using a real-world quantum computer, in which lasers shuffle around ions on a chip to explore the strange behavior of qubits. By creating a special, knotted structure of entangled particles, the team demonstrated that today’s quantum machines can already outperform classical strategies in certain tasks, and with [...]
