According to quantum theory,if the quantum state of a particle exists in the quantum state of "left" and "right",it can be freely converted under the condition of no external force,that is,there is a phenomenon of quantum superposition,which can only be clarified when measuring.Einstein et al.proposed the "quantum entanglement" thought experiment to question the rationality of "quantum superposition".In recent years,many reports have suggested that "quantum entanglement" seems to have an action at a distance faster than the speed of light,and is considered to be of great significance in communication confidentiality.In this paper,the chemically common D-and L-phenylalanine are used to simulate the "left" and "right" states in quantum entanglement.Two key problems are studied through experiments: 1)Phenylalanine molecules is there a quantum superposition phenomenon between the intramolecular and intermolecular D-and L-states? 2)Is there an action at a distance between the D configuration and the L configuration of the phenylalanine molecule? The experimental results show that: 1)There is an energy barrier between D-and L-phenylalanine molecules,which can not be converted freely under the action of no external force,that is,the D-and L-quantum states in a single molecule cannot be randomly stacked,and intermolecular D-and L-states can be superimposed;2)when the D-or Lphenylalanine molecules undergo chiral conversion under the action of external force,respectively,when they become L-or D-phenylalanine,they correspond.The entangled molecule L-or Dphenylalanine molecule still maintains the L-or D-quantum state and does not correspond to the transition of the chiral quantum state.That is,no action at a distance occurs,and even close-range effects do not exist.This work means that,at least in the molecular model of phenylalanine,there is a superposition of quantum states between molecules,but there is no quantum superposition effect in the molecule,and there is no information action at a distance between molecules.That is,"quantum superposition" cannot exist arbitrarily.The hand performance barrier between the "left" and "right" states is its essential cause,indicating that at least the quantum state of the phenylalanine molecule is in fact localized.
