Localization and pattern formation in Wigner representation via multiresolution

Antonina N. Fedorova, Michael G. Zeitlin

We present an application of variational-wavelet analysis to quasiclassical calculations of solutions of Wigner equations related to nonlinear (polynomial) dynamical problems. (Nai…

Seven Principles of Quantum Mechanics

Igor V. Volovich

The list of basic axioms of quantum mechanics as it was formulated by von Neumann includes only the mathematical formalism of the Hilbert space and its statistical interpretation.…

Quantum chaos and fractals with atoms in cavities

M. Uleysky, L. Kon'kov, S. Prants

We study the coupled translational, electronic, and field dynamics of the combined system "a two-level atom + a single-mode quantized field + a standing-wave ideal cavity". We deri…

Noncommutative probability in classical systems

Andrei Khrennikov, Sergei Kozyrev

Two examples of the situation when the classical observables should be described by a noncommutative probability space are investigated. Possible experimental approach to find quan…

Quantum Information and Spacetime Structure

Igor V. Volovich

In modern quantum information theory one deals with an idealized situation when the spacetime dependence of quantum phenomena is neglected. However the transmission and processing…

Geometric coupling thresholds in a two-dimensional strip

D. Borisov, P. Exner, R. Gadyl'shin

We consider the Laplacian in a strip with the boundary condition which is Dirichlet except at the segment of a length of one of the boundaries where i…

Easy Control over Fermionic Computations

Yuri Ozhigov

Quantum fermionic computations on occupation numbers proposed in quant-ph/0003137 are studied. It is shown that a control over external field and tunneling would suffice to fulfill…

Quantum communication complexity of symmetric predicates

Alexander Razborov

We completely (that is, up to a logarithmic factor) characterize the bounded-error quantum communication complexity of every predicate depending only on ($x,y\…

Quantum Computer with Fixed Interaction is Universal

Yuri Ozhigov, Leonid Fedichkin

It is proved that a quantum computer with fixed and permanent interaction of diagonal type between qubits proposed in the work quant-ph/0201132 is universal. Such computer is contr…

New type of fields in Maxwells equations: their properties and method of detection

A. G. Chirkov, A. N. Ageev

A theoretical analysis of the excitation of an infinitely long solenoid by oscillating current has revealed the existence of specific potentials in the space outside the solenoid,…

Problems in realization of large-scale ensemble silicon-based NMR quantum computers

A. A. Kokin, K. A. Valiev

Problems in realization of silicon-based solid-state NMR quantum computer with ensemble addressing to qubits are considered. It is presented the extension of Kane's scheme to ensem…
