Fujitsu and RIKEN announced the development of a 256-qubit superconducting quantum computer at the RIKEN RQC-FUJITSU Collaboration Center, expanding on their previous 64-qubit system introduced in 2023 under Japan’s Quantum Leap Flagship Program (Q-LEAP). The new machine, designed to support broader applications in fields such as molecular analysis and error correction research, will become available to companies and research institutions globally in the first quarter of fiscal 2025 as part of Fujitsu and RIKEN’s hybrid quantum computing platform. This development marks a substantial increase in computational capabilities within the same platform, offering users an upgraded environment to advance quantum research and [...]

SandboxAQ has launched AQtive Guard, a new cybersecurity platform designed to protect against the rapidly growing threats posed by Non-Human Identities (NHIs)—autonomous AI agents increasingly used across enterprise environments. As AI agents exceed one billion in number, AQtive Guard offers real-time vulnerability detection, automated remediation, and full lifecycle management of cryptographic assets such as keys, certificates, and algorithms. Built on SandboxAQ’s Large Quantitative Models (LQMs), the platform features two core modules including Discover which provides accurate inventory of NHIs and cryptographic assets and Protect which orchestrates automated protection workflows and credential management. Key functions within these two core modules include the [...]

By Joe Spencer Aegiq and BT, along with other partners successfully demonstrated performance of their Quantum Link Assurance System (QLAS) at Adastral park in Suffolk, England. Funded through UK Research and Innovation (UKRI), the Quantum Link Assurance System solves an important operational obstacle for the commercial adoption of fibre-based QKD, by offering independent link validation. The solution is designed to seamlessly fit into standard optical fibre communications networks. GQI attended the demo at Adastral Park to view the system and get a better understanding of the wider impact of this project.  What Is It? First, it’s important to highlight that QLAS [...]

Quantum error correction (QEC) is a hot topic these days so GQI has created a 21 page document that provides an in-depth analysis of the current state of the art in quantum error correction research. This document cover all the key aspects for understanding the current status of quantum error correction including the following main themes: The "Standard Model" of large-scale FTQC based upon the surface code Recent progress and demonstrations related to the surface code High overheads and the need for innovation Emerging alternative quantum error correcting codes Key challenges for fault-tolerant quantum computing (The "Sputnik Moment") Fundamentals of quantum [...]

Project Eleven (P11) has announced the QDay Prize, an open competition offering a reward of one Bitcoin (current value about $85,000) for demonstrating the ability to break elliptic curve cryptography (ECC) using Shor’s algorithm on a quantum computer. Participants must submit quantum programs that directly solve the elliptic curve discrete logarithm problem (ECDLP) without relying on classical shortcuts or hybrid methods. Submissions must include gate-level code and system specifications, and all entries will be made publicly available for transparency. The competition is structured around progressively larger ECC key sizes, starting from 1-bit keys, with an emphasis on demonstrating generalizable techniques that [...]

Researchers from NASA’s Jet Propulsion Laboratory (JPL), alongside private partners AOSense, Infleqtion, and Vector Atomic, are advancing the Quantum Gravity Gradiometer Pathfinder (QGGPf) project to demonstrate quantum-based gravity measurements in space. Supported by NASA’s Earth Science Technology Office (ESTO), the mission will deploy a compact quantum sensor aboard a spacecraft to map variations in Earth's gravitational field with unprecedented sensitivity. The QGGPf system will use two clouds of ultra-cold rubidium atoms as test masses to measure differential acceleration through quantum wave interference. The sensor is designed to be significantly smaller and lighter than traditional gravity gradiometers, occupying about 0.25 cubic meters [...]

Quminex, a Canadian startup focused on quantum-AI-powered mineral exploration, has secured pre-seed investments from QV Studio, Quantacet, and Quantonation. The funding will support technology development and company growth, with Quminex emerging as one of the first portfolio companies under QV Studio’s program at Distriq in Sherbrooke, Quebec. The investors cited Quminex’s combination of deep quantum computing and geoscience expertise as a catalyst for innovation in sustainable resource discovery. Alongside the funding announcement, Quminex was selected as a Top Innovator in the Quantum for Society Challenge organized by the World Economic Forum’s UpLink platform. The challenge targets scalable quantum solutions aligned with [...]

IonQ has signed a memorandum of understanding (MoU) with Intellian Technologies, a South Korea-based global provider of satellite communication antennas, to explore the integration of quantum networking into satellite communications. The collaboration will focus on evaluating secure satellite-to-satellite and ground-to-satellite communications using quantum technologies, as well as potential applications such as quantum time synchronization as an alternative to GPS. The agreement builds on IonQ’s long-term engagement in South Korea’s quantum ecosystem. Previous milestones include partnerships with major South Korean institutions such as Seoul National University, Sungkyunkwan University, and SK Telecom, as well as joint research efforts with Hyundai Motor Company on [...]

Equal1 has achieved a key milestone in silicon-based quantum computing by validating the formation of multiple tunable quantum dots using a commercial CMOS process based on GlobalFoundries’ 22FDX® FD-SOI platform. The demonstration marks the first time a commercial foundry process has been used to form tunnel-coupled quantum-dot arrays, establishing a foundation for scalable spin qubit architectures. Equal1’s monolithic chip integrates 29 NMOS and PMOS quantum cells and has demonstrated robust operational stability across cryogenic temperatures ranging from 70 mK to 1.2 K. The technology transforms multi-gate transistors into linear quantum-dot arrays with integrated charge sensors, enabling scalable spin qubit development using [...]

Rendering of a Q4S Satellite Containing Entanglement Swapping Device. Credit:Boeing HRL Laboratories and Boeing have completed construction and validation of a fully integrated quantum communication subassembly for Boeing’s Q4S satellite mission, which aims to demonstrate four-photon quantum entanglement swapping in orbit. The subassembly includes an optical board, control electronics, and thermo-mechanical packaging in a 15 kg, space-qualified payload. It is currently undergoing end-to-end software verification and environmental testing at Boeing’s El Segundo Space Simulation Laboratory. The validated system will serve as the ground twin for the on-orbit payload currently in production. The Q4S mission is designed to demonstrate entanglement swapping, a [...]
