Abstract Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that independent instances of a noisy process behave as perfect quantum communication channel when used in coherent superposition alternative orders. This phenomenon occurs even if original has zero capacity to transmit information. In contrast, does not occur mess...

A taxonomy organizes concepts or topics in a hierarchical structure and can be created manually or via automated systems. One major drawback of taxonomies is that they require users to have the same view of the topics as the taxonomy creator. That is, when a user follows a top-down path to find the specific topic of her interest, she has to make choices along the constrained sequence that is pr...

Feynman path integrals provide an elegant, classically inspired representation for the quantum propagator and dynamics, through summing over a huge manifold of all possible paths. From computational simulational perspectives, ergodic tracking whole is hard problem. Machine learning can help, in efficient manner, to identify relevant subspace intrinsic structure residing at small fraction vast m...

the dependence of some thermodynamic properties of spin-polarized liquid 3he such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. the lennard-jones potential has been used in our calculations. it has been found that for higher values of entropy, the spin polarization has greater ef...
