Quantum sensor for the atomic world

Groundbreaking potential

26-Jul-2024 - In a scientific breakthrough, an international research team from Germany's Forschungszentrum Jülich and Korea's IBS Center for Quantum Nanoscience (QNS) developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held ...

Electron vortices in graphene detected

“Thanks to our extremely sensitive sensor and high spatial resolution, we didn’t even need to cool down the graphene...”

14-May-2024 - Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor – such as a metal wire – is connected to a ...

A miniature magnetic resonance imager made of diamond

Quantum sensors make microscale NMR spectroscopy possible

23-Oct-2023 - The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research ...

Seeing clearly into a new realm – researchers prototype a new generation of quantum microscopy

“What began as an experimental annoyance ended up being a hint towards a capability of our microscope that is unique among current alternatives”

11-Nov-2022 - While quantum computing seems like the big-ticket item among the developing technologies based on the behaviour of matter and energy on the atomic and subatomic level, another direction promises to open a new door for scientific research itself – quantum microscopy. With the advance of quantum ...

Quantum sensors: Measuring even more precisely

Better measurements with little extra effort

25-Mar-2022 - Two teams of physicists led by Peter Zoller and Thomas Monz at the University of Innsbruck, Austria, have designed the first programmable quantum sensor, and tested it in the laboratory. To do so they applied techniques from quantum information processing to a measurement problem. The innovative ...

Quantum microscope for inspection of magnetic materials at the nanoscale

Swiss start-up Qnami closes 2.6M CHF seed round

14-Nov-2019 - Qnami announced the closing of a CHF 2.6M (USD 2.6M) seed round led by Venture Capital fund Quantonation and further supported by investiere, ZKB Start-up Finance and the High-Tech Gründerfonds. The funds will support the market entry of Qnami’s first product, a quantum microscope for inspection ...

Redefining the Limits of Measurement Accuracy

Researchers develop more sensitive quantum sensors

03-Jul-2019 - For centuries, humans have been expanding their understanding of the world through more and more precise measurement of light and matter. Today, quantum sensors achieve extremely accurate results. An example of this is the development of atomic clocks, which are expected to neither gain nor lose ...

Sensor the size of a nitrogen atom investigates hard drives

04-Jan-2018 - Integrated circuitry is becoming increasingly complex. These days a Pentium processor contains some 30 million transistors. And the magnetic structures found in hard drives measure just 10 to 20 nanometers across – less than a flu virus at 80 to 120 nanometers in diameter. Dimensions are rapidly ...

Quantum Sensors for High-Precision Magnetometry of Superconductors

04-May-2016 - Scientists at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds ...
