The discussion centers on the existence of an operator for the existence of an object in quantum mechanics. Participants debate the notion that prior to measurement, there is no information about the object's existence. A counterpoint is raised regarding quantum optics experiments where detection signals indicate the presence of photons, suggesting that knowledge of an object's existence may be possible even before measurement. The conversation highlights the complexities of quantum measurement and the implications for understanding object existence.
PREREQUISITESQuantum physicists, researchers in quantum mechanics, and students studying quantum optics will benefit from this discussion, particularly those interested in the philosophical implications of measurement and object existence in quantum theory.
rar0308 said:Before a measurement we don't have any information about a object. So we don't know about a existence of the object. But we are trying to measure something of the object. Is there operator of existence of a object? All operators commute with this?
