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.

From smart textiles to self-driving cars: Empa researchers are developing new types of detectors for infrared radiation that are more sustainable, flexible and cost-effective than conventional technologies. The key to success is not (only) the composition of the material, but also its size.

It has been proven, in the incredibly tiny quantum realm, by an international team co-led by UC Santa Cruz physicist Jairo Velasco, Jr. In a new paper published on November 27 in Nature, the researchers detail an experiment that confirms a theory first put forth 40 years ago stating that electrons confined in quantum space would move along common paths rather than producing a chaotic jumble of trajectories.

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.

Aeluma, Inc., a semiconductor company specializing in high-performance, scalable technologies for mobile, automotive, AI, defense and aerospace, communication and quantum computing, today announced it has been awarded a contract by NASA to develop quantum dot photonic integrated circuits (PICs) on silicon. This advanced technology targets next-generation space and aerospace applications, enabling capabilities such as free-space laser communication, autonomous navigation, and precision sensing.

Researchers have successfully created electrically defined quantum dots in zinc oxide (ZnO) heterostructures, marking a significant milestone in the development of quantum technologies.

Researchers have discovered a way to recycle the tiny particles used to create supraparticle lasers, a technology that precisely controls light at a very small scale. Supraparticle lasers work by trapping light inside a tiny sphere made of special particles called quantum dots, which can absorb, emit, and amplify light very efficiently.

Quantum pioneer Diraq has won the Defence, Dual-Use Technology and Space category at the InnovationAus 2024 Awards for Excellence for its tech advancements that could see the potential of quantum computing reach a commercial reality.

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.

On November 13th 2024, Quandela, the CNRS, Université Paris-Saclay, and Université Paris Cité inaugurated at the Centre for Nanoscience and Nanotechnology (CNRS/Université Paris-Saclay/Université Paric Cité) the QDlight associated research laboratory focusing on research in quantum photonics, which is to say the art of controlling light in the quantum regime inside nanoscale devices. Over the course of six years, the teams will expand scientific cooperation with a view to developing next generation quantum light emitters, as well as their applications in quantum information technology to secure unprecedented computing power.
