What is Quantum Theory and How Does it Apply to Classical Entities?

In summary, quantum theory is a branch of physics that explains the behavior of particles at a subatomic level. It describes how particles such as electrons and photons exist in multiple states or positions simultaneously until they are observed or measured. This theory also explains the concept of entanglement, where particles can become connected in a way that their properties are dependent on each other, regardless of distance. Quantum theory applies to classical entities by showing that the laws of classical physics are just an approximation of the underlying quantum mechanics at a larger scale. It helps explain the duality of particles, where they can behave as both waves and particles, and the uncertainty principle, which states that the position and momentum of a particle cannot be known simultaneously. Overall, quantum theory has
