LabQ Software to operate Qnami's Quantum Microscope

The complete scanning NV system consists of the ProteusQ quantum microscope, a microwave signal generator with a photon counting module, and the system software.

While our quantum microscope will give you new insight into the nanoworld, we did not want the quantum machinery behind it to get in your way. Built upon the open-source Qudi framework, the LabQ software intuitively guides you through the different measurement modes so that you get the answers you need as quickly as possible.
