Optical measurement techniques are increasingly used in surgery for real-time tissue analysis. This technology is particularly important for monitoring during tumor removal, as it helps to detect any malignant cells that may still be present. These innovative techniques will also improve therapies for patients in the future. To this end, researchers from Dresden are collaborating with the Dutch company Single Quantum, which specializes in quantum technology, and Absolut System SAS, a French cryogenic engineering consultancy. They want to bring sensors that have so far only been used in quantum computing and communication to the operating room. An EU grant totaling EUR 5 million over four years is supporting the consortium in developing and implementing this technology.

A Japanese research team, led by Professor Dr. Toru Asahi, Researcher Dr. Kenta Nakagawa, and master’s student Keigo Tokita from the Faculty of Science and Engineering, Comprehensive Research Organization at Waseda University, investigated the origin of the strong optical anisotropy of lead-doped Bi2212 single crystals using ultraviolet and visible light transmittance measurements.

EPA grants $1.5 million to four universities, including Stevens, to detect and degrade PFAS ‘forever chemicals’ in soil and water using quantum and materials science techniques.

Quantum Dice, a University of Oxford spin-out pioneering quantum random number generator (QRNG) technology, has joined the sixth cohort of the Digital Security by Design (DSbD) Technology Access Programme, a UK government-backed initiative, that aims to integrate secure-by-design principles into the development of resilient technologies.

UbiQD, Inc., the New Mexico-based leader in quantum dot (QD) technology and manufacturing, announced today a new technology assistance award with Los Alamos National Laboratory (LANL) under the Technology Readiness Gross Receipts (TRGR) Initiative. This collaboration focuses on leveraging the lab's Nanotechnology and Advanced Spectroscopy Team capabilities, led by LANL fellow Victor Klimov, to advance UbiQD's R&D on near-infrared (NIR) emitting QDs, specifically for applications in solar energy.

In the effort to develop new quantum technologies of the future, scientists are pursuing several different approaches. One avenue seeks to use molecules as the fundamental building blocks of quantum technologies. Now scientists at Caltech have figured out a new way to use ultrafast laser pulses to realize an important quantum mechanical property known as superposition, turning a relatively simple molecule into a quantum sensor—a tool that can measure chemical phenomena in its surroundings through inherently quantum means.

Recently, a team led by the Laboratoire d’Optique Appliquée (CNRS), in collaboration with ICREA Professor at ICFO Jens Biegert and other multiple institutions (Institut für Quantenoptik - Leibniz Universität Hannover, Fraunhofer Institute for Applied Optics and Precision Engineering IOF, Friedrich-Schiller-University Jena), demonstrated the quantum optical properties of high-harmonic generation in semiconductors. The results, appearing in Physical Review X Quantum, align with the previous theoretical predictions about HHG.

In a recent study, researchers from Chiba University delved into a promising path toward solid-state optical cooling using perovskite quantum dots. Focused on anti-Stokes photoluminescence, a process in which materials emit higher-energy photons than they absorb, this research could revolutionize the existing cooling technology. Their findings highlight both the potential and limitations of this novel cooling approach, with exciting prospects in energy-saving technology.

Scientists have devised an experiment for testing the domain of validity of quantum theory for objects much more massive than the usual microphysical objects (atoms, molecules etc), beyond which the classical theory has to be necessarily used. This study can also help in developing high precision quantum sensors which are important tools in the cutting- edge quantum technologies.

A team led by Prof. LU Zhengtian and Researcher XIA Tian from the University of Science and Technology of China (USTC) realized Schrödinger-cat state with minute-scale lifetime using optically trapped cold atoms, significantly enhancing the sensitivity of quantum metrology measurement. The study was published in Nature Photonics.
