Die optische Atomuhr geht in die Anwendung: Vakuumtechnische Herausforderungen auf dem Weg der Miniaturisierung

For The Most Accurate Time: The Optical Atomic Clock Enters Application. The age of quantum technologies has begun. This is accompanied not only by the availability of additional physical quantities, which require a general rethink, but also by modified devices in which such states can be made possible. Within the opticlock project, an optical ion clock is being developed that exceeds today's standard of time measurement by more than a factor of ten in terms of stability and accuracy. An essential component of the opticlock is the compact vacuum chamber. The appropriate material, a design precisely tailored to the application, tight manufacturing tolerances and precision cleaning in accordance with defined Vacom standards allow the opticlock chamber to be transferred from a highly complex laboratory setup into a user-friendly and transportable overall system. The targeted transfer of scientific research results to industry and their economic realization form the basis for developing a robust and durable optical ion clock, which can even be operated outside a specialized laboratory for the first time. © 2019, Wiley-VCH Verlag.
