The University of Sheffield has opened a new ultra-low temperature facility for dark matter and qubit research, providing a hub for students in the UK and expanding the scope of quantum technology research at the university. The University selected the ProteoxMX, a state-of-the-art dilution refrigerator and superconducting magnet manufactured by Oxford Instruments NanoScience for its facility.

In a recent breakthrough, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Northern Illinois University discovered that they could use light to detect the spin state in a class of materials called perovskites (specifically in this research methylammonium lead iodide, or MAPbI3). Perovskites have many potential uses, from solar panels to quantum technology.

Qunova Computing, a developer of quantum software applications designed to bring quantum computing to the chemical, pharmaceutical and industrial engineering industries, today announces the results from a series of recent tests performed on three different NISQ era quantum computers, each with a different qubit count. In each demonstration, Qunova’s algorithm was able to produce results with accuracy below the threshold of 1.6 millihartrees required for real-world quantum chemistry applications, a level known as ‘chemical accuracy’. This marks the first time this has been achieved on a commercially available device.

A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and the Max Planck Institute for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light microscope, down to one nanometer and with Ångström precision. The intra-molecular resolution achieved with MINFLUX microscopy makes it possible to optically record the spatial distances between subunits in macromolecules and thus to detect different conformations of individual proteins in the light microscope.

Dr. Habib Rostami, from the Department of Physics at the University of Bath, has co-authored pioneering research published in Advanced Science. This study involved an international collaboration between an experimental team at Friedrich Schiller University Jena in Germany and theoretical teams at the University of Pisa in Italy and the University of Bath in the UK. The research aimed to investigate the ultrafast opto-electronic and thermal tuning of nonlinear optics in graphene.

A recent study, published in Nature Photonics, by Prof. Yaron Bromberg and Dr. Ohad Lib from the Racah Institute of Physics at the Hebrew University of Jerusalem has made significant strides in advancing quantum computing through their research on photonic-measurement-based quantum computation.

A research team led by the Department of Energy’s Oak Ridge National Laboratory has devised a unique method to observe changes in materials at the atomic level. The technique opens new avenues for understanding and developing advanced materials for quantum computing and electronics.

Physicists like to measure things, and they like those measurements to be as precise as possible. That means working at unfathomably small scales, where distances are much smaller than even the diameters of subatomic particles. Researchers also want to measure time down to a precision of less than one second per tens of billions of years. The quest for these ultraprecise measurements in physics is part of a growing field called quantum metrology.

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.

The new design developed by Dash and the lab of U-M physicist Georg Raithel uses a special kind of laser beam that traps atoms in a pinwheel-shaped geometry, which can be scaled from a 30 micron radius, smaller than the diameter of a human hair, and up to about 10 times larger, about 300 microns. The researchers’ design is published in the journal AVS Quantum Science.
