Core Viewpoint - The research conducted by scientists from the Chinese Academy of Sciences has successfully discovered and actively controlled the "preheating" phase of a quantum system on a superconducting chip, laying the groundwork for more stable and controllable quantum computing and simulation [1][2]. Group 1: Quantum System Dynamics - Quantum thermalization refers to the process where a quantum system gradually reaches a state of equilibrium, leading to the diffusion of energy and information, which poses a significant challenge for quantum computing that requires long-term information retention [1]. - The preheating phase is an intermediate stage in the thermalization process where the system remains in a relatively stable state before entering complete chaos, akin to ice absorbing heat at 0 degrees Celsius without immediate temperature rise [1]. Group 2: Research Methodology and Findings - Researchers innovatively employed a method called "random multipole driving" to manipulate the quantum system, successfully extending or shortening the duration of the preheating phase through carefully designed non-periodic and self-similar driving sequences [2]. - The study demonstrated that during the platform phase, the growth of chaos in the system was significantly suppressed, while crossing the platform led to a rapid increase in complexity and swift information diffusion throughout the system [2]. Group 3: Implications for Quantum Computing - This research marks the first instance of actively controlling the preheating process beyond periodic driving in a quantum simulator, providing new insights for designing better quantum error correction schemes and extending the coherence time of quantum bits [2]. - The findings validate the unique advantages of quantum simulators in addressing specific complex problems, promoting a synergistic relationship between quantum and classical computing [2].
