薛定谔猫，又“变胖”了

Group 1 - The research team from Austria and Germany has created the largest quantum superposition state to date using approximately 7,000 sodium atoms, representing the highest "macro degree" of Schrödinger's cat [1][2] - The experiment was conducted in a super high vacuum environment at 77 Kelvin (approximately -196 degrees Celsius), confirming the quantum wave properties of sodium atom clusters with a diameter of about 8 nanometers [2] - This new achievement aids in understanding the boundary between microscopic and macroscopic scales of matter, which is crucial for the development of quantum computers that require qubits to maintain coherent superposition states for effective computation [2]
