The ProteusQ provides the necessary power to probe the magnetic homogeneity of these bits with the required spatial resolution and sensitivity, even before electrical characterization. The Qnami ProteusQ has been effectively utilized to image its electrical and magnetic domains. Although the signals from two-dimensional magnets are minuscule, they can still be detected by the ProteusQ, aiding researchers in understanding the textures of these ultrathin magnets. With the Qnami ProteusQ, we can visualize their remaining uncompensated spins, which are found at domain walls, crystalline edges, or within nanostructures. Using the ProteusQ, we successfully imaged ultrascaled nanowires as narrow as 6 nm and demonstrated our ability to capture fragile spin vortices and artificial spin ice textures without causing disturbances. Furthermore, the ProteusQ can quantitatively image microwave emissions from interconnects and antennas.

Quantilever MX+ represents the state-of-the-art quantum diamond tips that deliver the highest demonstrated signal-to-noise ratio for scanning NV magnetometry. The innovative tip design maximizes the light collection efficiency while ensuring an optimal distance between the NV center and the sample surface. Equip Qnami ProteusQ with the Quantilever MX+ quantum diamond tips to further enhance its sensing performance. With their high signal-to-noise ratio, Quantilever MX+ diamond probes unlock the measurement of even weaker magnetic fields. The Product Offer Pillar Geometry: Parabolic Signal-to-noise ratio: 3-times higher than with conventional tip design Magnetic Sensitivity: ~ 3μT/(Hz)1/2 Patent Family: WO2021151796A1 System: Qnami ProteusQ Single Units CHF 2800 1 Quantilever MX+ Starting Pack CHF 5600 2 probes from our Quantilever MX + series and 2 probes from our Quantilever DX series Measure extremely weak magnetic fields The high signal-to-noise ratio and sensitivity of Quantilever MX+ further facilitate the characterization of materials with extremely weak stray fields such as antiferromagnets or multiferroics. Perform SNVM at cryogenic temperatures Quantilever MX+ enables higher photon count rates and directional photon emission with minimal losses allowing the use of objective lenses with small NA and relaxing potential working distance constraints. Perform AC magnetometry Due to the higher signal-to-noise ratio and photon count rates, AC magnetometry protocols benefit drastically from reduced measurement time. Groundbreaking design The latest cutting-edge design advancement in diamond tips made commercially available. Highest precision Up to 3 times higher SNR compared to conventional tip designs. Highly efficient measurements Record-low laser powers and photon emission into minimal numerical aperture. The innovative design is the result of a fruitful collaboration with the Quantum Sensing Lab (led by Prof. Patrick Maletinsky) at the University of Basel. The innovation initiated through the work done by Hedrich et al in 2020 and continued through technoloy transfer with the Qnami Quantum Foundry who optimized the fabrication process and made it the third generation of Qnami Quantilevers. Optimized pillar geometry To effectively guide photons toward optics The parabolic shape effectively guides emitted photons toward the collection optics. The flat end facet ensures the proximity between the NV center and the sample surface preserving the high spatial resolution in magnetometry measurements. Improved photonic waveguide To maximize signal collection The parabolic reflector guides on average 80% of the emitted photons toward the collection optics. The concentrated photon flux allows the use of objectives with small NA (<0.5) and relaxes potential working distance constraints. State-of-the-art fabrication techniques To icrease the signal to noise ratio Signal-to-noise ratio enhanced – parasitic background fluorescence is minimized by optimal nanofabrication. Integration times in the sub-ms range are unlocked through high NV signal and minimized noise leading to improved statistics. Diamond Tips for Nanoscale Resolution The optimized design of the Quantilever MX+ pillar maximizes the light collection efficiency while preserving the nanoscale resolution.
