Laboratoř optiLAB kolegů z oddělení optických sítí sdružení CESNET nedávno otestovala nově pořízený systém kvantové distribuce klíčů (QKD) typu TOSHIBA LD, který představuje špičku v oblasti bezpečné kvantové komunikace. Tento systém umožňuje generování a distribuci kryptografických klíčů na základě kvantových jevů, čímž zajišťuje extrémně vysokou úroveň zabezpečení proti odposlechu. Pořízení QKD systému je součástí širší strategie rozvoje kvantově bezpečné infrastruktury a jeho nasazení otevírá nové možnosti pro výzkum v oblasti kvantové kryptografie a fyziky jednoho fotonu.

Vladimír Pavlík left us forever on 27 February 2025. Vláďa was part of the team of people who brought the Internet to the Czech Republic, or more precisely, connected the Czech Republic to the global Internet. He was able to talk about this period very beautifully and with humour. He was one of the last living true experts on the first commercial Unix platforms, such as the SunOS and later Solaris operating systems from SUN. Managing these systems was a real art, comparable, for example, to playing the violin, which he also mastered. At CESNET, for many years, he w

Pavel Vachek left us forever on February 3, 2025. His name brings to mind words such as modesty, humility, diligence, willingness, reliability, generosity. And such First Republic gentlemanliness. And a great outlook. He could talk to anyone, not only about work, but also about literature, politics, family, faith - in short, about life. But underneath the kind, unassuming veneer, there was also an expert with immense knowledge, which he was happy to impart. Andrea Kropáčová: Pavel was one of my first teachers after joining CESNET.
