Measuring tiny magnetic fields, such as those generated by brain waves, enables many new novel opportunities for medical diagnostics and treatment. The research team led by Dr. Jan Jeske at Fraunhofer IAF is working on a globally innovative approach to precise magnetic field measurements: Laser Threshold Magnetometry. The researchers have now combined an NV diamond and a laser diode in a resonator, successfully demonstrating the sensor system with two active media for the first time. This outstanding paper has been published in Science Advances and represents a significant progress in the BMBF-funded research project NeuroQ.

Interlune , a natural resources company, today announced a $365,000 grant from the U.S. Department of Energy (DOE) to pursue new technology that would separate Helium-3 from domestic Helium supplies. Notably, the proposed approach would not require the production of additional tritium, which is used for nuclear weapons and decays into Helium-3 over time.

Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high resolution than traditional diamond tips used in scanning probe magnetic-field microscopes.

In a new paper published in Physical Review Research, Tohoku University's Dr. Le Bin Ho explores the effectiveness of the squeezing technique in enhancing the precision of measurements in quantum systems with multiple factors. The analysis provides theoretical and numerical insights, aiding in the identification of mechanisms for achieving maximum precision in these intricate measurements.

Recent experiments have collected microscopic information precisely of the kind hidden by such topological censorship. The work by Douçot, Kovrizhin, and Moessner provides a detailed microscopic theory that goes beyond such topological censorship. It not only identifies an unexpected phenomenon – the meandering edge state carrying topologically quantized current – at variance with common expectations, but also identifies mechanisms that allow for tuning between qualitatively different microscopic implementations corresponding to one and the same topologically protected global quantity.

Now, researchers from SUO Liumin’s team and LIU Gangqin’s team from Institute of Physics of the Chinese Academy of Science have developed a quantum sensing approach based on diamond nitrogen-vacancy (NV) centers.

A breakthrough in quantum technology research could help realise a new generation of precise quantum sensors that can operate at room temperature. The research—carried out by an international team of researchers from the University of Glasgow, Imperial College London, and UNSW Sydney—shows how the quantum states of molecules can be controlled and sensitively detected under ambient conditions.

Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of a scanning tunneling microscope.

Researchers at Chalmers University of Technology have for the first time succeeded in combining two major research fields in photonics by creating a nanoobject with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices.

Prof. Michał Parniak and Michał Lipka from the University of Warsaw (UW) is Faculty of Physics developed a quantum-inspired super-resolving spectrometer for short pulses of light. In the future the device can be miniaturized on a photonic chip and applied in optical and quantum networks as well as in spectroscopic studies of matter. The invention was presented by the researchers in “Optica”.
