To get Qnami ProteusQ ready for market in record time, Cosylab supported Qnami in developing, manufacturing, and CE-marking MicrowaveQ, its quantum control hardware.
To succeed, Cosylab exploited its vast experience in delivering FPGA applications with giga-samples per second transmission rate and real-time control systems for advanced physics machines.
QNAMI AND THE FIRST QUANTUM MICROSCOPE
Qnami’s mission is to develop quantum sensing solutions for a broad range of applications from materials science and electronics to biomedical systems. Its goal is to support the development of technologies that improve people’s life. The company aims to support quantum applications in the following domains:
- High resolution imaging
- Quantum sensing
- Quantum computing
- Medical/Bio solutions
Qnami ProteusQ is the first complete Quantum Microscope that allows to measure magnetic fields never measurable before. At the core of the Qnami ProteusQ microscope is the Quantilever: an all-diamond probe engineered with one single nitrogen-vacancy centre at the apex of its tip. The Quantilever probe scans surfaces with extreme precision and allows non-perturbative analysis of a large variety of magnetic materials.
The microscope’s physics
The NV centre is a point defect in a diamond lattice, where two carbon atoms have been swapped for a nitrogen atom and a vacancy immediately alongside. By trapping one extra electron, the nitrogen-vacancy centre acquires spin properties making it an atomic-sized compass. The quantum state of the NV centre can be assessed by measuring its red fluorescence response to green laser excitation. The intensity of this response signal encodes quantum information related to the NV centre’s spin state. Local magnetic fields will alter this spin state. Thus, controlling such state enables the characterization of tiny magnetic fields which lay nanometres below the probe tip.
A detector in the Qnami ProteusQ optically captures the measurement data by counting single photons of the response signal at a very high rate. A quantum control hardware must serialise, process, convert and transfer the data to a computer that runs the high-level imaging and managing application for the Qnami ProteusQ.
