Rapid Test for Topological 2D Materials: Researchers from the Würzburg-Dresden Cluster of Excellence ct.qmat have developed a method with which two-dimensional topological materials can be detected more easily and quickly.

Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly in applications such as secure communications and high-resolution imaging. However, many materials that contain SPEs are impractical for use in mass manufacturing due to their high cost and the difficulty of integrating them into complex devices.

The unique properties of quantum physics could help solve a longstanding problem that prevents microscopes from producing sharper images at the smallest scales, researchers say. The breakthrough, which uses entangled photons to create a new method of correcting for image distortion in microscopes, could lead to improved classical microscope imaging of tissue samples to help advance medical research.

The heart of future quantum devices could be lit up by arrays of tiny glow-sticks, developed by ANU physicists.A group from the Department of Electronic Materials Engineering (EME) manufactured an array of tens of thousands of indium phosphide nanowires and made them glow by incorporating single quantum dot emitters into them.

A recent study, spearheaded by Boaz Lubotzky during his PhD research, along with Prof. Ronen Rapaport from the Racah Institute of Physics at The Hebrew University of Jerusalem, in collaboration with teams from Los Alamos National Laboratory (LANL) in the USA and from Ulm University in Germany, unveiled a significant advancement toward the on-chip integration of single-photon sources at room temperature. This achievement represents a significant step forward in the field of quantum photonics and holds promise for various applications including quantum computing, cryptography, and sensing.

Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.

Researchers at the University of California San Diego have used an advanced optical technique to learn more about a quantum material called Ta2NiSe5 (TNS).
