Core Insights - Chinese scientists have achieved a novel quantum state known as "thermal" topological edge states on a 100-bit superconducting quantum chip, addressing the challenge of thermal noise interference in symmetry-protected topological edge states [1][3] - The research was conducted by teams from Zhejiang University and Tsinghua University, and published in Nature on August 27 [1] Group 1: Research Findings - The study demonstrates that topological edge states, which are stable quantum states bound to the edges of a quantum system, are typically susceptible to thermal noise and exist only at absolute zero [1] - The research team introduced a theoretical concept called "preheating" to protect symmetry-protected topological edge states from thermal excitation [3] - Experiments conducted on the "Tianmu 2" superconducting quantum chip, which features 125 superconducting qubits, confirmed the effectiveness of the "preheating" mechanism in creating robust long-lived topological edge states [3] Group 2: Implications - The findings provide new experimental methods for exploring topological states at finite temperatures, which are above absolute zero, showcasing the application value of superconducting quantum chips in simulating novel states [3] - This research opens new pathways for developing quantum storage systems that are resistant to noise at finite temperatures [3]
