Physicists from the University of the Witwatersrand (Wits) have developed an innovative computing system using laser beams and everyday display technology, marking a significant leap forward in the quest for more powerful quantum computing solutions.

A research team led by Dominik Schneble, PhD, Professor in the Department of Physics and Astronomy, has uncovered a novel regime, or set of conditions within a system, for cooperative radiative phenomena, casting new light on a 70-year-old problem in quantum optics.

Recently, a team led by the Laboratoire d’Optique Appliquée (CNRS), in collaboration with ICREA Professor at ICFO Jens Biegert and other multiple institutions (Institut für Quantenoptik - Leibniz Universität Hannover, Fraunhofer Institute for Applied Optics and Precision Engineering IOF, Friedrich-Schiller-University Jena), demonstrated the quantum optical properties of high-harmonic generation in semiconductors. The results, appearing in Physical Review X Quantum, align with the previous theoretical predictions about HHG.

Karlsruhe Institute of Technology Joins IQST as a New Partner.

Quandela, the European leader in photonic quantum computing, announces the recruitment of two senior profiles for the positions of Chief Financial Officer and Business Development Director. These recruitments are set to bolster a team of over 100 employees from 20 different nationalities, primarily composed of researchers and engineers specializing in optics, algorithms, and information sciences.

A team at the Department of Experimental Physics and the Institute of Quantum Optics and Quantum Information (IQOQI) led by Francesca Ferlaino has successfully isolated single atoms of erbium in optical tweezer arrays. This achievement enables a groundbreaking approach to the study of elements with multiple valence electrons —a realm previously dominated by simpler atoms with one or two valence electrons. Erbium, which possesses 14 valence electrons, introduces new degrees of freedom and opens up exciting opportunities for quantum experimentation, enabling the exploration of previously uncharted atomic behaviors.

Lightmatter, the leader in photonic supercomputing, today announced a strategic collaboration with Advanced Semiconductor Engineering, Inc. (ASE, a member of ASE Technology Holding Inc.), the world’s largest semiconductor packaging and testing services provider. The partnership will focus on advancing Lightmatter’s Passage platform, the world’s first 3D-stacked photonics engine with pluggable fiber, to overcome the critical AI interconnect bottlenecks hindering today’s data center infrastructure. This breakthrough enables scaling to millions of XPUs at the speed of light to meet the unprecedented demands of AI workloads.

Quantum Computing Inc. ("QCi" or the "Company"), an innovative, integrated photonics and quantum optics technology company, today announced that it has entered into a securities purchase agreement for the purchase and sale of 16,000,000 shares of common stock at a purchase price of $2.50 per share, priced at-the-market under Nasdaq rules, pursuant to a registered direct offering, resulting in gross proceeds of $40 million, before deducting placement agent commissions and other offering expenses. The closing of the offering is expected to occur on or about November 18, 2024, subject to the satisfaction of customary closing conditions.

A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon light stream.

One new study, conducted by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University, investigated ways to reliably grow diamond at lower temperatures than those currently used. Diamond has properties that make it attractive to the semiconductor industry. With its particular crystal lattice structure, diamond can withstand high electrical voltages. It’s also very good at dissipating heat.
