Quantum Correlations in Two-Fermion Systems
John Schliemann, J. Ignacio Cirac, Marek Kus +2
We characterize and classify quantum correlations in two-fermion systems having 2K single-particle states. For pure states we introduce the Slater decomposition and rank (in analog…
Atom Optics with Microfabricated Optical Elements
G. Birkl, F. B. J. Buchkremer, R. Dumke +1
We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical el…
Loading of a Bose-Einstein condensate in the boson-accumulation regime
F. Floegel, L. Santos, M. Lewenstein
We study the optical loading of a trapped Bose-Einstein condensate by spontaneous emission of atoms in excited electronic state in the Boson-Accumulation Regime. We generalize the…
Separable approximations of density matrices of composite quantum systems
S. Karnas, M. Lewenstein
We investigate optimal separable approximations (decompositions) of states rho of bipartite quantum systems A and B of arbitrary dimensions MxN following the lines of Ref. [M. Lewe…
Quantum Cloning and Distributed Measurements
Dagmar Bruss, John Calsamiglia, Norbert Lütkenhaus
We study measurements on various subsystems of the output of a universal 1 to 2 cloning machine, and establish a correspondence between these measurements at the output and effecti…
Realistic teleportation with linear optical elements
C. Trump, D. Bruss, M. Lewenstein
We calculate the highest possible information gain in a measurement of entangled states when employing a beamsplitter. The result is used to evaluate the fidelity, averaged over al…
