Quantum Mpemba Effect: Chaos Orders Itself Faster ⚡ экспресс
The quantum Mpemba effect is a surprising phenomenon where a system far from equilibrium reaches equilibrium faster than a more balanced one. In a new study, physicists propose a mechanism based on decoherence-free subspaces (protected quantum states) and show that the relaxation speed can increase exponentially with system size, creating an extreme effect. They also examine the subtleties of defining the effect through quantum trajectory analysis and build a microscopic model to understand the environment's role. It's like when thick smoke clears faster than light haze, thanks to special internal structures.
Hot water sometimes freezes faster than cold — this is the Mpemba effect. In the quantum world, it’s even more astonishing: a system bubbling with disorder (with high entropy) can settle incredibly faster than one that is almost calm.
The solution lies in islands of silence within any system — regions untouched by the destructive noise of the environment.
The larger the system, the more such regions exist, and the calming cascades like an avalanche. A mathematical model confirmed that the speed grows exponentially: large structures seem to sweep out disorder with acceleration.
The discovery not only explains the paradox but also provides a key to ultra-stable quantum computers: instead of fighting noise, we can harness its rapid neutralization.
