Abstract

"Atom chips" allow the manipulation of ultra-cold laser cooled atoms using micro fabricated wire structures. Current carrying wires on the chip surface generate inhomogeneous magnetic fields, allowing cold atoms to be held by the same forces as those in the famous Stern-Gerlach experiment. By varying the wire currents atoms can be squeezed into small volumes, and put at specific distances relative to surfaces.

Abstract

PLEASE NOTE THE NEW COLLOQUIUM TIME AND LOCATION IN QNC.

Is it possible to certify that the n-bit output of a physical random
number generator is "really random"? In the classical World this seems
impossible.

Abstract

When systematic errors are ignored in an experiment, the subsequent analysis of its results becomes questionable. We develop tests to identify systematic errors in experiments where only a finite amount of data is recorded and apply these tests to tomographic data taken in an ion-trap experiment. We put particular emphasis on quantum state tomography and present two detection methods: the first employs linear inequalities while the second is based on the generalized likelihood ratio.

Abstract

The birth of quantum key distribution (QKD) 2 decades ago was accompanied by headlines the world over that the age of perfect security had finally dawned. The media, not noted for its restraint, can be forgiven. But so, too, can the physicists who, by and large, spawned such claims. In the cut-throat world of research funding, quantum key distribution was a godsend. I played the game too.
