Fluctuation of Quantum Information Density in Curved Time-Space

Abstract:
A dynamical equation for quantum information density （QID） in curved spacetime is presented. The related fluctuation of QID with quantum Einstein equation is also discussed, which reveals the measuring of the dynamical mutual information condition using a Gaussian quantum channel.[著者文摘]
