Quantum computers love the cold. But how to connect them if any wire brings lethal heat? Scientists used quantum teleportation and sent a microwave signal between fridges through a 'hot' channel at 4 K. Even in such hellish (by quantum standards) conditions, transmission fidelity beat the classical record. So, a quantum internet can be built without total deep-freeze.
🎯 The operating temperatures of qubits (millikelvins) are hundreds of times colder than interstellar space.
🎬 Unlike the teleporter in Star Trek, what's transferred here is not matter but a quantum state—a kind of 'subatomic fax'.
