Qnami ProteusQ

Qnami ProteusQ is a complete quantum microscope system. It is the first scanning NV (nitrogen-vacancy) microscope for the analysis of magnetic materials at the atomic scale. The Qnami ProteusQ system comes with state-of-the-art electronics and software. Its flexible design allows for future adjustments and scaling, expansion and capability upgrades. The proprietary Qnami ProteusQ quantum technology provides high precision images for you to see directly the most subtle properties of your samples and the effect of microscopic changes in your design or fabrication process.

Next level in precision

The Qnami ProteusQ opens a new window on your research and gives you a new level of control to drive innovation in the design, creation and delivery of smart and energy-efficient electronics.

PRECISE

Map a wide range of magnetic signals down to the single atomic layer with nanoscale resolution for material science and more.

INTUITIVE

Automated operations, tip and sample exchange in just a few minutes. You don’t even need quantum expertise.

EVOLUTIVE

Adjust, expand and upgrade your ProteusQ. Synchronize measurements and run your own protocols with the Jupyter Notebook (Python).

LabQ software

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

While the Qnami ProteusQ will give you new insight to the nano world, 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.

  • From fast sample preview to detailed analysis
  • Simultaneous mapping of topography and magnetic fields
  • Fluorescence auto-track mode
  • Write your own scripts and run custom-made protocols

We hope you will have as much fun using the Qnami ProteusQ as we had making it!
