Popis: We have investigated quantum noise and decoherence due to primordial gravitons with minimum uncertainty initial states. This condition allows the initial state to be in the form of an entanglement or a superposition state. We got that the increasing number of gravitons in the initial state of entanglement can increase the effective strain corresponding to the quantum noise and can reduce the dimensions of the experimental setup system. The existence of non-diagonal elements in the initial superposition state allows the distribution of the quantum noise to be non-Gaussian. In addition, these non-diagonal terms also cause the quantum noise to occur for a very long time compared to the initial state in the form of a Bunch-Davies vacuum.
