For decades, quantum entanglement has demanded near-absolute-zero conditions to survive — a requirement that has kept the technology locked inside well-funded laboratories behind walls of cryogenic machinery. Researchers have now demonstrated a nuclear-spin swap technique that extends entanglement's room-temperature lifetime by up to 240 times, moving quantum systems from microseconds to milliseconds of coherence. This is not merely a technical refinement; it is a quiet renegotiation of the terms under which quantum technology might enter the world.
