Optimal Cloning of Pure States, Judging Single Clones
M. Keyl, R. F. Werner
We consider quantum devices for turning a finite number N of d-level quantum systems in the same unknown pure state σinto M>N systems of the same kind, in an approximation of the M…

Optimal Cloning of Pure States
R. F. Werner
We construct the unique optimal quantum device for turning a finite number of d-level quantum systems in the same unknown pure state σinto M systems of the same kind, in an approxi…

Isotopic Composition of Solar Wind Calcium: First in Situ Measurement by CELIAS/MTOF on Board SOHO
R. Kallenbach, F. M. Ipavich, P. Bochsler +11
We present first results on the Ca isotopic abundances derived from the high resolution Mass Time-of-Flight (MTOF) spectrometer of the charge, element, and isotope analysis system…
