By taking two flakes of special materials that are just one atom thick and twisting them at high angles, researchers at the University of Rochester have unlocked unique optical properties that could be used in quantum computers and other quantum technologies. In a new study published in Nano Letters, the researchers show that precisely layering nano-thin materials creates excitons—essentially, artificial atoms—that can act as quantum information bits, or qubits.

A collaboration bringing together UBC Blusson QMI researchers with industry and government partners is set to accelerate research and commercialization of innovative photonic chips. With over $1 million in funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the National Research Council Canada (NRC), the project aims to overcome key integration challenges in embedding quantum light sources into semiconductor-based platforms.

Sensing and communication systems based on quantum-mechanical phenomena can greatly outperform today’s systems, in terms of accuracy and reliability, and are considered a pivotal part of developing next-generation networks. Developing quantum information and decision systems that come close to meeting the theoretical quantum advantages has been a longstanding challenge. Now, a team of researchers at MIT and the University of Ferrara (UniFe) in Italy has developed a framework that could open up new ways of pushing such quantum systems all the way to their fundamental limits.

Physicists at the University of Cologne have taken an important step forward in the pursuit of topological quantum computing by demonstrating the first-ever observation of Crossed Andreev Reflection (CAR) in topological insulator (TI) nanowires. This finding, published under the title ‘Long-range crossed Andreev reflection in topological insulator nanowires proximitized by a superconductor’ in Nature Physics, deepens our understanding of superconducting effects in these materials, which is essential for realizing robust quantum bits (qubits) based on Majorana zero-modes in the TI platform — a major goal of the Cluster of Excellence ‘Matter and Light for Quantum Computing’ (ML4Q).

Infleqtion, a global leader in quantum information technologies, has been awarded $6.2 million in funding from the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) to develop quantum-enhanced solutions for energy grid optimization. This marks the first-ever quantum technology award granted by ARPA-E and represents the largest grant awarded under the agency’s OPEN program this year.

BTQ Technologies Corp. (the "Company"), a global quantum technology company focused on securing mission-critical networks, is pleased to announce the appointment of Dr. Gavin Brennen as Chief Quantum Officer (CQO). Dr. Brennen, who has already been serving as Quantum Information Advisor and Director of BTQ Australia, will now also drive the company's global technological roadmap and strategy.

QuamCore, a deep tech startup redefining quantum computing scalability, announced today its emergence from stealth with $9 million in seed funding. Founded in 2022, QuamCore has spent the past two years developing its breakthrough superconducting quantum processor architecture, working in stealth mode to solve the critical scalability challenges that have long prevented practical quantum computing. The company has now emerged with a patented architecture that enables the integration of 1 million qubits into a single cryostat - a milestone previously thought impossible. This breakthrough dramatically reduces the size, energy consumption, and cost of quantum computers, unlocking practical applications across pharmaceuticals, AI, materials science, and energy.

Led by Professor Pasquale Scarlino at EPFL, they developed a superconducting Kerr resonator, a device with controllable quantum properties, and engineered it to experience a two-photon drive, which sends pairs of photons into the system to carefully control its quantum state and study how it transitions between different phases.

The University of Maryland (UMD) and the global quantum computing firm Xanadu have established a strategic partnership to drive innovation, workforce development, and commercialization across the state of Maryland and the wider Mid-Atlantic region.

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.
