next Tuesday

Dear all, Next Tuesday's talk will be in the Pauli Room at 5pm by Shun Watanabe. Roger Title: Tomography increases key rates of quantum key distribution protocols Abstract: We construct a practically implementable classical processing for the BB84 protocol and the six-state protocol that fully utilizes the accurate channel estimation method, which is also known as the quantum tomography. Our proposed processing yields at least as high key rate as the standard processing by Shor and Preskill. We show two examples of quantum channels over which the key rate of our proposed processing is strictly higher than the standard processing. In the second example, the BB84 protocol with our proposed processing yields a positive key rate even though the so-called error rate is higher than the 25% limit.

Dear all, (Ilona: please announce the first paragraph on the QSIT page) On Tuesday, Sandu Popescu will be giving the talk: "Multiple time states and multiple time measurements" (see http://arxiv.org/abs/0712.0320). This will be in ETH Zentrum, Kuppelraum HG K30.1 at 17:00 Research day will also be there this week, but for the afternoon only (from 14:00). Those of you who dedicate your lives to Sandu's boxes will no doubt also be interested in his talk at the theory colloquium on Monday (see http://www.theorycolloquium.phys.ethz.ch/ for details) Cheers, Roger
