The best compact emitters of light are quantum dots—semiconductor nanocrystals with quantum mechanical behaviours thanks to their small size (2–10 nanometres). The emitted light goes in all directions and has poor polarisation, but placing it next to nanostructures enables directional emission or circular polarisation. Simultaneous control of both direction and polarisation, however, has never been achieved. In their paper “Unidirectional chiral emission via twisted bi-layer metasurfaces”, Associate Prof Wu and her team set out to bridge this gap.

Adtran today announced that Switzerland’s Federal Institute of Metrology METAS has successfully deployed its OSA 3300 HP, improving national timekeeping performance and supporting critical scientific research. As the industry’s first high-performance optical cesium atomic clock, the OSA 3300 HP sets new standards for accuracy and stability, while assuring 10 years of operation. It also strengthens Switzerland’s contribution to Universal Time Coordinated (UTC), bolstering its position in the global timekeeping network. By providing an ultra-stable frequency source, the OSA 3300 HP offers major advances in the field of metrology, ensuring that Switzerland remains at the forefront of precision measurement and timekeeping.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced it has won the GBx Best in British Tech Award in the Deep Tech Innovation category.

Quantum technologies exploit the unusual properties of the most fundamental building blocks of matter. They promise breakthroughs in communication, computing, sensors and much more. However, quantum states are fragile, and their effects are difficult to grasp, making research into real-world applications challenging. Empa researchers and their partners have now achieved a breakthrough: Using a kind of “quantum Lego”, they have been able to accurately realize a well-known theoretical quantum physics model in a synthetic material.

Zero Point Cryogenics (ZPC) offers a practical and high-performing solution for low-temperature research with their newest product line: the Continuous Cold Cryostats. These systems are workhorses designed for continuous operation around 1 K, and optimized to meet the needs of labs requiring both cool-down, high cooling power, and rapid sample exchange, while maintaining the quality and reliability of all ZPC systems. The Continuous Cold systems are an ideal choice for researchers who don't require a dilution refrigerator's millikelvin temperature range but still desire an upgradable path and ease of use for sensitive experiments in fields like quantum technology and materials science.

For the first time, EPFL researchers have exclusively observed molecules participating in hydrogen bonds in liquid water, measuring electronic and nuclear quantum effects that were previously accessible only via theoretical simulations.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, announced that the Company has been awarded a fifth project from the National Aeronautics and Space Administration (NASA) to develop quantum remote sensing technology that would significantly lower the cost of spaceborne LIDAR imaging and advance scientific understanding of the mechanisms of climate change.

Researchers from the Department of Energy’s Oak Ridge National Laboratory have taken a major step forward in using quantum mechanics to enhance sensing devices, a new advancement that could be used in a wide range of areas, including materials characterization, improved imaging and biological and medical applications.

Q.ANT, the leading German startup for light-based data processing and quantum sensing, is unveiling the first prototypes of the Q.M 10, the next generation of its photonic quantum magnetic field sensor. This groundbreaking sensor redefines the way biosignals are captured and processed in medical technology by measuring the tiniest electric currents and magnetic fields in the human body with even greater precision than its predecessor, and without direct contact. By leveraging light as a natural carrier of information, the Q.M 10 gives researchers deeper insights into the body’s biosignals and promises to push the boundaries of medical technology. One example is mind-controlled prosthetics that function almost like natural limbs. In collaboration with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), Q.ANT is developing an innovative prosthetic sensor module, showcasing it at this year’s COMPAMED international trade fair in Düsseldorf, taking place from November 11-14. Visitors can experience a live demonstration at Hall 8a, Booth G10, demonstrating how the Q.M 10 converts emulated muscle signals into precise commands for a hand prosthesis in milliseconds.

The University of Queensland will pioneer quantum sensory methods that could improve the detection of performance-enhancing drugs in the lead up to the Brisbane 2032 Olympic and Paralympic Games.
