Hot water freezes faster than cold—that's the Mpemba effect. In the quantum world, its counterpart is a system with a highly broken symmetry restoring order faster. Scientists controlled this on a superconducting chip, turning an accelerated 'tightening' of disorder on and off. This could help quant

Ordinary particles don't change when swapped. But there are special 'knotty' ones that remember the path. For twenty years, scientists hunted for a variety called Majorana zero modes, crucial for quantum computing. In a new experiment on a microdevice, they performed a swap for the first time, confi
