Dynamics of multi-qubit states in non-inertial frames for quantum communication applications

Abstract: In this paper, some properties of multi-qubit states traveling in non-inertial frames are investigated, where we assume that all particles are accelerated. These properties are including fidelities, capacities and entanglement of the accelerated channels for three different states, namely, Greeberger-Horne-Zeilinger (GHZ) state, GHZ-like state and W-state. It is shown here that all these properties are decreased as the accelerations of the moving particles are increased. The obtained results show that the GHZ-… Show more

“…To establish this approximation, one demands that a specific wave packet accessible to an accelerating observer should correspond with a well-localized wave function in their inertial frame. QT with two and three observers in non-inertial frames has been studied in [37] and [38] respectively. Also, quantum entanglement and teleportation in the presence of noise in non-inertial frames has been the subject of recent research.…”
