The Compatibility between the Non-local Quantum Interaction and the Finite Transmission Speed of Light and Information: Revisiting the Uncertainty Principle
This work shows that in the frame of the stochastic generalization of the quantum hydrodynamic analogy (QHA) the uncertainty principle is fully compatible with the postulate of finite transmission speed of light and information. The theory shows that the measurement process performed in the large scale classical limit in presence of background noise, cannot have a duration smaller than the time need to the light to travel the distance up to which the quantum non-local interaction extend itself. The product of the minimum measuring time multiplied by the variance of energy fluctuation due to presence of stochastic noise shows to lead to the minimum uncertainty principle. The paper also shows that the uncertainty relations can be also derived if applied to the indetermination of position and momentum of a particle of mass m in a quantum fluctuating environment.

The paper investigates the non-local property of quantum mechanics by analyzing the role of the quantum potential in generating the non-local dynamics and how they are perturbed in presence of noise.The resulting open quantum dynamics much depend by the strength of the Hamiltonian interaction: Weakly bounded systems may not be able to maintain the quantum superposition of states on large distances and lead to the classical stochastic evolution.The stochastic hydrodynamic quantum approach shows that the wave-function collapse to an eigenstates can be described by the model itself and that the minimum uncertainty principle is compatible with the relativistic postulate about the light speed as the maximum velocity of transmission of interaction.The paper shows that the Lorenz invariance of the quantum potential does not allow superluminal transmission of information in measurements on quantum entangled states.
