A functional quantum computer is one of the most intriguing promises of quantum technology. With significantly increased computing power, quantum computers will be able to solve tasks that conventional computers cannot handle, such as understanding and inventing new materials or pharmaceuticals as well as testing the limits of cryptographic techniques. In order to reduce error rates and provide reliable operations much faster, researchers at Leibniz University Hannover and Physikalisch-Technische Bundesanstalt (PTB) have developed a new method based on trapped ions. Their findings have been published in the latest issue of the scientific journal “Physical Review Letters”.

Eine Thorium-Kernuhr könnte noch einmal deutlich genauer sein als alle bisherigen Cäsium- und auch die optischen Atomuhren. Das verspricht Vorteile für die Anwendungen präziser Zeit- und Frequenzmessung, aber auch für physikalische Grundlagenforschung. Nachdem das internationale Forschungskonsortium mit mehreren Veröffentlichungen bereits gezeigt hat, dass eine solche Uhr grundsätzlich realisierbar ist, zeigt nun der europäische Forschungsrat sein Vertrauen in das Projekt, indem er es mit insgesamt 13,8 Millionen Euro fördert. An dem interdisziplinären und internationalen Projekt „Thorium Nuclear Clock“ sind neben der Physikalisch-Technischen Bundesanstalt (PTB) Wissenschaftler aus Wien, München, Delaware (USA), Heidelberg und Aachen beteiligt. Das Synergy Programm des European Research Council (ERC) ist die am höchsten dotierte Forschungsförderung des ERC und konzentriert sich insbesondere auf Themen mit hohem Innovationspotenzial, die...
