Compound objects as particles in quantum mechanics

By analyzing the decay of a compound system into two praticles, we show that measurements on particle 1 will define with an arbitrary degree of precision the coordinate and momenta of particle 2 at times large compared with the lifetime of the compound system, i.e., when the two particles no longer interact. Thus we have an example of the Einstein–Podolsky–Rosen argument in which all the requirements of quantum mechanics are met. Criticism of the point of view they present should then center on their epistemological position (such as their definition of physical reality) rather than on their use of the quantum-mechanical formalism.

Elementary particles are the common capital of any being in the universe. However, a being is characterized by its behavior as well as its capital and the principle of least action shows the common behavior of partners that transfer energy. However, the concept of action does not apply to all transfers; what is the action when two men transfer words? Here we show that the “principle of greatest freedom” reveals the common behavior of any partner during nondestructive relationship that is to maximize the number of its accessible states, i.e., its freedom. It gives a common interpretation to quantum mechanics, to wave-particle duality and to relativity. It defines the coherent relationship, which explains why objects behave consistently according to laws and why they construct compound beings that evolve.

Recent progress in synthetic chemistry and molecular quantum optics has enabled demonstrations of the quantum mechanical wave-particle duality for complex particles, with masses exceeding 10 kDa. Future experiments with even larger objects will require new optical preparation and manipulation methods that shall profit from the possibility to cleave a well-defined molecular tag from a larger parent molecule. Here we present the design and synthesis of two model compounds as well as evidence for the photoinduced beam depletion in high vacuum in one case.
