Classical states are generally robust against decoherence, which occurs when a quantum system interacts with its environment, leading to a loss of quantum coherence. The discussion explores the implications of classical states decohering and questions how macroscopic objects, like a table or a window, would behave under such conditions. It highlights the concept of environment-induced superselection (Einselection), which suggests that certain states, known as pointer states, are less affected by decoherence. The conversation also touches on Quantum Darwinism, which posits that observers can learn about a system's state without disturbing it, thus preserving the object's integrity. Overall, the dialogue emphasizes the complex relationship between quantum mechanics and our understanding of objective reality.
