Quintessent Inc., a pioneer in quantum dot laser technology and heterogeneous silicon photonics, and IQE plc, the leading global supplier of advanced epitaxial wafer products and services, have partnered together to establish the world’s first large-scale quantum dot laser and semiconductor optical amplifier (SOA) epitaxial wafer supply chain. This collaboration, supported by purchase order commitments from Quintessent, will see IQE deliver production quantities of epitaxial wafers to Quintessent throughout 2025.

The simultaneous capability of colloidal QDs to sustain robust room-temperature spin quantum coherence and to engage in photochemistry inspired Prof. WU Kaifeng and his team from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences to explore a highly interdisciplinary field—using quantum coherence of QDs to control photochemical reactions.

A ground-breaking study published in Advanced Materials showcases a significant advancement in laser technology, promising more affordable and scalable solutions for applications ranging from environmental monitoring to biomedical imaging. Researchers have developed the first colloidal quantum dot (CQD)-based laser capable of operating across the entire extended short-wave infrared (SWIR) spectrum.

MicroCloud Hologram Inc., (the "Company"), based on their in-depth research and continuous innovation in quantum technology, they have pioneered an advanced technological solution: using a fast adiabatic driving protocol to achieve coherent control of two heavy hole spin qubits in a double quantum dot (QD) system. In traditional quantum experimental protocols, conventional methods such as linear ramps, π-pulses, or Landau-Zener channels have contributed to the incremental development of quantum control techniques. However, due to their inherent physical limitations, these methods struggle to meet the current stringent demands for high fidelity in quantum information processing. In contrast, the fast adiabatic driving protocol developed by HOLO demonstrates significant technological advantages.

Scientists at EPFL have made important progress in quantum technology, achieving strong coupling between quantum dots in Germanium and microwave photons, paving the way for scalable quantum computing based on spin qubits.

This week, at the 2024 IEEE International Electron Devices Meeting (IEDM), imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, and its partners in the Belgian project Q-COMIRSE, present a first of its kind prototype shortwave infrared image sensor with indium arsenide quantum dot photodiodes. The sensor demonstrated successful 1390 nm imaging results, offering an environmentally friendly alternative to first-generation quantum dots that contain lead, which limited their widespread manufacturing. The proof-of-concept is a critical step toward mass-market infrared imaging with low-cost and non-toxic photodiodes.

Quobly, a leading French quantum computing startup, has reported that FD-SOI technology can serve as a scalable platform for commercial quantum computing, leveraging traditional semiconductor manufacturing fabs and CEA-Leti's R&D pilot line.

A team of researchers from the University of Cologne, Hasselt University (Belgium) and the University of St Andrews (Scotland) has succeeded in using the quantum mechanical principle of strong light-matter coupling for a groundbreaking optical technology that overcomes the long-standing problem of angular dependence in optical systems. The study ‘Breaking the angular dispersion limit in thin film optics by ultra-strong light-matter coupling’ published in Nature Communications presents ultra-stable thin-film polariton filters that open new avenues in photonics, sensor technology, optical imaging and display technology. The study at the University of Cologne was led by Professor Dr Malte Gather, director of the Humboldt Centre for Nano- and Biophotonics at the Department of Chemistry and Biochemistry of the Faculty of Mathematics and Natural Sciences.

Researchers at QuTech have managed to, for the first time, perform coherent logic operations between spin qubits 250 micrometers apart on the same chip. Such ‘enormous’ distances create new opportunities for operations between qubits, as they normally only sustain over 100 nm. These results hold promise for scalable networks of spin qubit islands on a chip. The researchers published their results in Nature Physics.

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.
