  • Publication number: 20250245541
    Abstract: A method of addressing at least one qubit to be addressed in a set of two or more qubits in diamond, comprises; exposing the qubit to be addressed to an electromagnetic field; and at the same time exposing another qubit of the set of two or more qubits to an electromagnetic counter field in such a way that the electromagnetic field has no effect on the other qubit or that the electromagnetic field has a different effect on the other qubit than on the qubit to be addressed.
    Type: Application

  • Patent number: 11391793
    Abstract: A device for generating and controlling a magnetic field strength and a method for generating and controlling a magnetic field strength are disclosed. The generation is very stable and precise. Preferably, reference values of physical variable can be generated relatively simply and economically. In addition, magnetic flux densities can be measured with high resolution and, in particular, highly robustly. The device and the method can also be used for transmitting information, in particular for ultra-wide band communication. The required devices can be very small, in particular miniature, and mobile.

  • Patent number: 9713482
    Abstract: The present invention relates to an improved cannula that enables a plurality of applications to such as tools to be utilized through a single cannula. According to the present invention there is a cannula having a distal end for insertion into a body, the distal end defining an opening to a primary conduit extending along the longitudinal axis of the cannula. The cannula further comprises a tool element for providing a tool function at or adjacent the distal end of the cannula. At least a portion of the tool element is arranged to be moveable outwardly relative to the longitudinal axis of the cannula. Accordingly, it is beneficial that more than one function can be provided at the distal end of the cannula reducing the trauma to the patient and improving access for the surgeon.
