European scientists are using diamonds to build a new quantum computer that works without needing to be cooled to ultra-low temperatures. This technological approach promises to make quantum computers more practical and scalable, leading, for example, to faster development of life-saving drugs and more powerful optimisation algorithms in the finance sector.

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.

A €10m consortium funded by the European Commission and supported by the Quantum Flagship is using diamond and silicon carbide to build quantum computers and quantum simulators that can run at room temperature. The SPINUS project is developing quantum simulators with more than 50 qubits and quantum computers with over ten qubits, the team expects that their research will provide a strategy to scale up to over 1000 and 100 qubits, respectively, within five years post-project.

Quantinuum, the world’s largest integrated quantum computing company, has signed a memorandum of understanding with Hamad Bin Khalifa University’s (HBKU) College of Science and Engineering (CSE). The College’s Qatar Center for Quantum Computing (QC2) will identify use cases in quantum chemistry, quantum machine learning, AI, and quantum-augmented cybersecurity.

In the QSolid collaborative project, Forschungszentrum Jülich and its partners have started operating the first prototype of a quantum computer with optimised qubit quality. It forms the basis of a future quantum computer being developed in Germany using superconducting qubits, which will be able to perform complex calculations for industry and research.

Purdue University has been selected by the U.S. Department of Energy (DOE) to lead the Quantum Photonics Integrated Design Center (QuPIDC) Energy Frontier Research Center (EFRC).

D-Wave Quantum Inc. (“D-Wave” or the “Company”), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, today announced that it has completed the calibration and benchmarking of a 4,400+ qubit Advantage2 processor. This milestone marks a significant step forward in D-Wave’s ongoing development of its sixth-generation annealing quantum computing system. The latest Advantage2 processor shows substantial performance gains over the current AdvantageTM system in solving customers’ complex computational problems in areas such as optimization, AI, and materials science.

A discovery by Rice University physicists and collaborators is unlocking a new understanding of magnetism and electronic interactions in cutting-edge materials, potentially revolutionizing technology fields such as quantum computing and high-temperature superconductors. Led by Zheng Ren and Ming Yi, the research team’s study on iron-tin (FeSn) thin films reshapes scientific understanding of kagome magnets — materials named after an ancient basket-weaving pattern and structured in a unique, latticelike design that can create unusual magnetic and electronic behaviors due to the quantum destructive interference of the electronic wave function.

Imagine a future where quantum computing is as accessible as the smartphone in your pocket. Where a quantum chip is embedded in your laptop, or thousands of quantum chips are deployed in supercomputing centres, forming the world’s most powerful quantum supercomputers. With this vision, Quantum Brilliance partnered with Pawsey Supercomputing Research Centre to develop the foundational steps of diamond-based room-temperature quantum computing. During this year’s Prime Minister Awards for Science, that bold ambition has been recognised, with Quantum Brilliance co-founder Dr Andrew Horsley named the 2024 New Innovator of the Year.

A research team led by Pacific Northwest National Laboratory (PNNL) scientists will use a combination of advanced electron microscopy, materials synthesis, and theoretical techniques to study quantum behavior in materials at the atomic level. They will use model material systems to study how electrons and their properties, such as spin and orbit, move through the materials. The project will focus on understanding transport phenomena, collectively known as Hall effects. Hall effects occur when an electric current flows through a material, typically in the presence of an external magnetic field, resulting in a build up of charge or spin in a direction perpendicular to the current flow.
