  • Patent number: 12367415
    Abstract: A photonic element for a quantum information processing device contains a high-purity silicon layer. The high-purity silicon layer contains integrated rare-earth element (REE) dopants at a concentration of 1019 cm?3 or less. An optical transition between the lowest crystal field levels of the REE dopants integrated in the high-purity silicon layer exhibits a homogeneous linewidth of 1 MHz or less at a temperature of 4 K or less. A method for producing such a photonic element is also disclosed.
    Type: Grant
    Filed: December 8, 2023
    Date of Patent: July 22, 2025
    Assignee: Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V.

  • Patent number: 10363788
    Abstract: A vibration damper is provided for a vehicle, preferably for a motor vehicle, having a wheel carrier made of metal for rotatably receiving a wheel, a damper tube arrangement at least partly made of a fiber-reinforced plastic for forming a damper fluid volume, a piston which is guided in the damper tube arrangement and includes a piston rod. The damper tube arrangement is rigidly connected to the wheel carrier and the piston rod can be connected to a body of the vehicle. A wheel carrier fluid volume is formed in the wheel carrier and which is connected to the damper fluid volume. The fluid in the wheel carrier fluid volume is in direct contact with the metal of the wheel carrier in order to transfer heat.
