Quantum Teleportation with Entangled States given by Beam Splittings
Karl-Heinz Fichtner, Masanori Ohya
Quantum teleportation is rigorously discussed with coherent entang led states given by beam splittings. The mathematical scheme of beam splitti ng has been used to study quantum co…
Symplectic Cuts and Projection Quantization
Martin Bojowald, Thomas Strobl
The recently proposed projection quantization, which is a method to quantize particular subspaces of systems with known quantum theory, is shown to yield a genuine quantization in…
Measuring quantum state overlaps of traveling optical fields
J. Clausen, M. Dakna, L. Knoll +1
We propose a detection scheme for measuring the overlap of the quantum state of a weakly excited traveling-field mode with a desired reference quantum state, by successive mixing t…
Nonclassical correlations in damped N-solitons
Eduard Schmidt, Ludwig Knoell, Dirk-Gunnar Welsch
The quantum statistics of damped higher-order optical solitons are analyzed numerically, using cumulant-expansion techniques in Gaussian approximation. A detailed analysis of noncl…
Continuous-variable teleportation improvement by photon subtraction via conditional measurement
T. Opatrny, G. Kurizki, D. -G. Welsch
We show that the recently proposed scheme of teleportation of continuous variables [S.L. Braunstein and H.J. Kimble, Phys. Rev. Lett. 80, 869 (1998)] can be improved by a condition…
Conditional quantum state engineering at beam splitter arrays
J. Clausen, M. Dakna, L. Knoell +1
The generation of arbitrary single-mode quantum states from the vacuum by alternate coherent displacement and photon adding as well as the measurement of the overlap of a signal wi…
