چکیده
We present mathematical techniques for addressing two closely related questions in quantum communication theory. In particular, we give a statistically motivated derivation of the Bures-Uhlmann measure of distinguishability for density operators, and we present a simplified proof of the Holevo upper bound to the mutual information of quantum communication channels. Both derivations give rise to novel quantum measurements.

A new type of nonlinear gauge quantum theory (superrelativity) has been proposed [1, 2, 3, 4, 5, 6]. Such theory demands a radical reconstruction of the quantum field conception and spacetime structure, and this paves presumably way to the comprehension of the quantum nature of inertia.

We discuss the relation between the Quantum Hall behaviour of charged carriers and their chaotic motion in phase space. It is shown that the quantum Hall diagram is comparable with the stepped diagram in phase space of a chaotic motion.

We obtain accurate result for the lightest glueball mass of QCD in 3 dimensions from lattice Hamiltonian field theory. Using the dimensional reduction argument, a good approximation for confining theories, we suggest that the 0 ++ glueball mass in 3+1 dimensional QCD be about 1.71 GeV.

We derive recursive equations for the characteristic numbers of rational nodal plane curves with at most one cusp, subject to point conditions, tangent conditions and flag conditions, developing techniques akin to quantum cohomology on a moduli space of stable lifts.

We use the correspondence between scalar field theory on AdSd+1 and a conformal field theory on R to calculate the 3and 4-point functions of the latter. The classical scalar field theory action is evaluated at tree level. e-mail: [email protected] e-mail: [email protected] 1
