Quantum Chaos Accelerates Beyond the Limit ⚡ экспресс
Scientists have discovered that in some quantum theories with extra symmetry, 'operator growth' (the process of quantum information becoming more complex) can violate what was thought to be a universal law — it becomes super-fast, growing quadratically rather than linearly. It's like a rumor that doesn't spread from person to person, but instantly sweeps through like an avalanche. Why does the 'extra' symmetry speed up entanglement so dramatically?
Usually, in quantum systems, information mixes gradually, like a rumor in a crowd: one person passes it to another, and that person to the next. The growth of entropy (a measure of disorder) is linear here – and was long considered a universal limit. But when additional symmetries come into play, a different picture emerges. In such systems, the influence of a single particle instantly spreads to many others – as if 'super-spreaders' appear, whispering the news to everyone at once. The entanglement speed skyrockets, and information covers the entire system almost instantly.
The discovery not only deepens the theory of quantum chaos but also promises ultra-fast quantum devices.
🎯 Black holes were considered champions of scrambling information: they reach the limit of chaos in a fraction of a second. The new discovery shows that some quantum systems can be even faster.
🎬 In Liu Cixin's 'The Three-Body Problem,' aliens instantly comprehend everything about humanity – just like information behaves in systems where speed limits are removed.
