Peter Fischer, a senior researcher at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), led a project to make 3D X-ray images of skyrmions that can characterize or measure the orientations of spins inside the whole object. “Our results provide a foundation for nanoscale metrology for spintronics devices,” Fischer said. The work was recently published in Science Advances.

Alisa Javadi, Ph.D., professor at the University of Oklahoma School of Electrical and Computer Engineering and the Homer L. Dodge Department of Physics and Astronomy, has received funding from the U.S. Department of Energy Early Career Research Program for research that offers the potential for advancing quantum technology development.

A research team has proposed a wind sensing lidar theory based on up-conversion quantum interference and successfully developed a prototype. Their work is published in ACS Photonics. The team was led by Prof. Xue Xianghui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS).

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory may have found a way to resolve this dilemma. It involves a scintillator material composed of spherical particles that are 20 billionths of a meter in size. Even though they are incredibly small, these nanoparticles have an intricate structure composed of a ball-like core of cadmium sulfide surrounded by a thin shell of cadmium selenide and a thicker shell of cadmium sulfide. Collaborating on this project were scientists from DOE’s Oak Ridge National Laboratory, Bowling Green State University (BGSU) and Northwestern University.

In a Nature Reviews Physics perspective article, researchers overview the latest advances regarding quantum phenomena within attosecond science, which are often overlooked despite their potential to influence experimental and theoretical outcomes.

A team of researchers from ICFO and the Royal Institute of Technology (KTH) from Sweden reports on APL Photonics the first demonstration of a photon pair source based on a silicon core fiber. The novel platform offers a unique combination of low propagation losses, high nonlinearity and compactness making it a promising candidate for scalable quantum applications.

Xiaoqian Chen, a physicist and beamline scientist at the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Brookhaven National Laboratory, has been selected as one of the 91 early career scientists from across the country to receive research funding through the DOE Office of Science’s Early Career Research Program. This funding will aid Chen in researching the unique ways that particles interact to share information due to quantum mechanics.

Researchers from TMOS, the ARC Centre of Excellence for Transformative Meta-Optical Systems, have developed a new engineering approach to on-chip light sources that could lead to widespread adoption of photonic chips in consumer electronics.

The advance shows promise for creating compact, inexpensive, and portable light sources, which are crucial for space-based applications, biological and geological field research, and military operations.

Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources.
