New quantum sensing method measures three light properties at once with high precision

A new method for measuring three different properties of light, at the same time, has been developed using an interferometry-based quantum sensing scheme capable of simultaneously estimating multiple parameters of an optical network.

The approach could help advances in the fields of medicine and astronomy, for example, to improve the precision and scope of quantum measurements across applications ranging from biological imaging to gravitational wave detection.

To date, it has only been possible to measure each parameter individually. However, research published in The European Physical Journal Plus has demonstrated, for the first time, that three independent optical parameters can be measured in a single “view” with ultimate quantum precision, without the need to examine each one of them individually.

Developers and expert users benchmark three leading open-source thermal conductivity calculation packages

Mechanical Engineering Professor Alan McGaughey of Carnegie Mellon University recently coordinated the Phonon Olympics, bringing togetherAlthough there’s no medal at the end of the Phonon Olympics, for McGaughey, the collaboration required to evaluate the accuracy of three widely used open-source thermal conductivity packages was worth more than gold.

For the last decade, researchers seeking to understand the properties of new materials have turned to open-source packages to perform thermal conductivity calculations. These packages enable a broader community to study , but until now users had no way of knowing whether or not each package would produce consistent and accurate results.

Quantum Route Redirect PhaaS targets Microsoft 365 users worldwide

A new phishing automation platform named Quantum Route Redirect is using around 1,000 domains to steal Microsoft 365 users’ credentials.

The kit comes pre-configured with phishing domains to allow less skilled threat actors to achieve maximum results with the least effort.

Since August, analysts at security awareness company KnowBe4 have noticed Quantum Route Redirect (QRR) attacks in the wild across a wide geography, although nearly three-quarters are located in the U.S.

Research drives commercialization of energy-efficient solar cell technology toward 40% efficiency milestone

Third-generation solar cell technology is advancing rapidly. An engineering research team at The Hong Kong Polytechnic University (PolyU) has achieved a breakthrough in the field of perovskite/silicon tandem solar cells (TSCs), focusing on addressing challenges that include improving efficiency, stability and scalability.

The team has conducted a comprehensive analysis of TSC performance and provided strategic recommendations, which aim to raise the energy conversion efficiency of this new type of solar cell from the current maximum of approximately 34% to about 40%.

The team hopes to accelerate the commercialization of /silicon TSCs through industry-academia-research collaboration, while aligning with the nation’s strategic plan of carbon peaking and neutrality and promoting the development of innovative technologies such as artificial intelligence through .
