Supersymmetry, quark confinement and the harmonic oscillator
S. A. Bruce, P. C. Minning
We study some quantum systems described by noncanonical commutation relations formally expressed as [q,p]=ihbar(I + chi H), where H is the associated (harmonic oscillator-like) Ham…
Experimental scheme for unambiguous discrimination of linearly independent symmetric states
O. Jiménez, X. Sánchez-Lozano, A. Delgado +1
We propose an optimal discrimination scheme for a case of four linearly independent nonorthogonal symmetric quantum states, based on linear optics only. The probability of discrimi…
State reconstruction for composite systems of two spatial qubits
G. Lima, F. A. Torres-Ruiz, L. Neves +3
Pure entangled states of two spatial qudits have been produced by using the momentum transverse correlation of the parametric down-converted photons [Phys. Rev. Lett. \textbf{94} 1…
Quantum information transfer for qutrits
A. Delgado, C. Saavedra, J. C. Retamal
We propose a scheme for the transfer of quantum information among distant qutrits. We apply this scheme to the distribution of entanglement among distant nodes and to the generatio…
