Controlled Hawking Process by Quantum Information
... In this presentation, we shed light on the problem by using a gedanken experiment of quantum energy teleportation (QET). The argument does not require un-established physics of quantum gravity. By using only semi-classical analysis, we can make significant statements about memory of black holes. In ...

A critique of recent theories of spin-half quantum plasmas
... as the density length-scale. The above estimate corresponds to a deliberately chosen “macroscopic” scale of 1m. Any smaller choice [e.g. LS ' 10−2 m] will make the current density estimate even larger! This corresponds to virtually a “saturation magnetic induction” of 0.1 to 1 Tesla, a value more t ...

Quantum Games and Quantum Strategies
... One might wonder what games and physics could possibly have in common. After all, games such as chess or poker seem to heavily rely on bluffing, guessing, and other activities of unphysical character. Yet, as was shown by von Neumann and Morgenstern [1], conscious choice is not essential for a theor ...

... there are two quite distinct ways for a quantum state to change. On the one hand there is unitary evolution, which is deterministic. If we specify the initial state |ψ(0)i, the theory predicts the state |ψ(t)i at a later time. But on the other hand there is measurement, which is probabilistic. The t ...
