他们在宏观尺度重现“薛定谔的猫”

Core Insights - The 2025 Nobel Prize in Physics was awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their groundbreaking experiments demonstrating quantum tunneling in macroscopic systems, revealing strange properties of the microscopic quantum world [1][4] Group 1: Quantum Tunneling and Superconductivity - Quantum tunneling, a phenomenon where particles can pass through energy barriers, was observed in a macroscopic object for the first time, challenging traditional views of quantum mechanics [1][5] - The experiments utilized superconductors, where electrons form Cooper pairs and behave as a collective quantum system, allowing for the observation of quantum effects on a larger scale [2][3] Group 2: Experimental Methodology and Findings - The researchers conducted a series of experiments on superconducting circuits, measuring the time it took for the system to escape a zero-voltage state through tunneling, thus demonstrating the quantum nature of the system [3][4] - They confirmed the quantization of energy in the system, showing that it could only absorb or emit energy in specific amounts, consistent with quantum mechanical predictions [3][4] Group 3: Implications and Future Research - This research not only enhances the understanding of quantum mechanics but also provides a new experimental platform for exploring the laws of the microscopic world, potentially leading to advancements in quantum technology [4][5] - The findings draw parallels to Schrödinger's cat thought experiment, emphasizing the existence of macroscopic systems that still adhere to quantum mechanical rules, thus holding significant conceptual importance in quantum physics [5]
