Using nuclear demagnetization—a method that extracts energy by removing a magnetic field—a 1.5-nanogram plate was passively cooled to 6.1 millikelvin. The residual jittering neatly obeyed the laws of thermodynamics. The record paves the way for gravitational wave detectors and testing quantum mechan

A tiny magnet levitates in a trap, unable to rotate freely. Scientists have found a way to protect its quantum 'leakage' through an energy barrier from residual gas interference: just make the magnet almost perfectly round. This discovery promises a breakthrough in creating ultra-sensitive sensors a
