Geometry of an adiabatic passage at a level crossing
Mateusz Cholascinski
We discuss adiabatic quantum phenomena at a level crossing. Given a path in the parameter space which passes through a degeneracy point, we find a criterion which determines whethe…
An iterative method for extreme optics of two-level systems
R. Parzynski, M. Sobczak, A. Plucinska
We formulate the problem of a two-level system in a linearly polarized laser field in terms of a nonlinear Riccati-type differential equation and solve the equation analytically in…
Erasure versus teleportation scheme of optical CNOT gate
Antoni Wojcik, Andrzej Grudka
We clarify the connections between the erasure scheme of probabilistic CNOT gate implementation recently proposed by Pittman, Jacobs and Franson [Phys. Rev. A 64, 062311 (2001)] an…
Two-way teleportation
Andrzej Grudka, Ravindra W. Chhajlany
A protocol for teleporting two qudits simultaneously in opposite directions using a single pair of maximally entangled qudits is presented. This procedure works provided that the p…
Generation of inequivalent generalized Bell bases
A. Wojcik, A. Grudka, R. W. Chhajlany
The notion of equivalence of maximally entangled bases of bipartite d-dimensional Hilbert spaces is introduced. An explicit method of inequivalent bases construction is presented.
Multiparty d-dimensional quantum information splitting
Andrzej Grudka, Antoni Wojcik
Generalization of quantum information splitting protocol from qubits to qudits (quantum d-dimensional systems) is presented.
