Pathways to Quantum Chaos on LEONARDO supercomputer
Quantum chaos in many-body systems poses unique challenges, as quantum systems evolve in a unitary, reversible manner that contrasts with classical chaotic dynamics, where particle trajectories diverge. The onset of quantum chaos carries implications across various fields, such as statistical physics, where it aligns with thermalization processes, and high-energy physics, where it helps explain information scrambling in black holes. In quantum information science, quantum chaos underpins quantum advantage, where fully programmable systems leverage quantum ergodicity to explore Hilbert space, performing computations beyond classical limits. However, entanglement alone doesn’t suffice for generating chaos: highly entangled states from the Clifford group, for example, remain classically simulable. True Quantum Chaos requires additional non-stabilizer resources, known as magic, which Clifford dynamics lack but non-Clifford gates, like T-gates, can introduce, resulting in exponentially complex states.
This project will enable the study of Quantum Chaos as a practical asset, with significant computational resources required for simulating chaotic dynamics.
