South Korean quantum software firm Norma Inc. has signed a Memorandum of Understanding with Rigetti Computing to deliver an 84-qubit quantum cloud service in South Korea. Announced during the Q2B Tokyo 2025 conference, the collaboration integrates Rigetti’s superconducting hardware with Norma’s Q Platform, enabling domestic users to access quantum resources through a localized, cloud-based interface. The specific system Rigetti will supply was not named, but the company recently introduced the Ankaa-3, an 84-qubit processor with a 99.5% median two-qubit gate fidelity, suggesting it may be the backend for the service. Rigetti has also previously deployed its hardware via Amazon Braket and [...]

Keysight Technologies has announced that its Quantum Control System (QCS) is embedded in the newly launched 256-qubit superconducting quantum computer developed by Fujitsu and RIKEN. The system, located at the RIKEN RQC-FUJITSU Collaboration Center in Japan, marks a significant milestone toward scalable, fault-tolerant quantum computation. As a modular and scalable platform, QCS enables both quantum-to-classical and classical-to-quantum conversions essential for high-fidelity quantum operations. The Fujitsu–RIKEN system is part of Japan’s broader quantum computing initiative and demonstrates how large-scale quantum processors will integrate with hybrid high-performance computing architectures, including GPUs and TPUs. Keysight’s QCS was selected for its RF performance and support [...]

IBM and Kipu Quantum have published new experimental results showing that a hybrid quantum algorithm—Branch-and-Bound Digitized Counterdiabatic Quantum Optimization (BBB-DCQO)—can outperform both classical and quantum annealing methods in solving higher-order unconstrained binary optimization (HUBO) problems. This algorithm combines a Bias-Field Digitized Counterdiabatic Quantum Optimization (BF-DCQO) with a branch-and-bound strategy to enhance the quality of the results. The algorithm, tailored specifically to IBM’s superconducting hardware and the HUBO problem class, was run on the IBM Heron quantum processor, achieving solution runtimes in fractions of a second—well below the minutes required by standard commercial solvers. The results, presented in two recent preprints, show [...]

The Netherlands’ HQ/2 initiative, involving QuTech, TNO, and four startups—QuantWare, Qblox, Orange Quantum Systems, and Delft Circuits—has released Tuna-5, a superconducting quantum system built using an open-architecture model. Hosted at the DiCarlo Lab and available via the Quantum Inspire platform, Tuna-5 integrates modular subsystems across hardware and software layers, including tunable-coupler quantum chips, modular control electronics, and Python-based software. The platform is intended as a system-readiness benchmark rather than a commercial-scale machine. Tuna-5’s processor, fabricated by QuantWare, incorporates flux-tunable couplers that allow dynamic adjustment of qubit interactions, improving gate fidelity and reducing spectator qubit interference. Control and readout are managed using [...]

Keyfactor has announced the acquisition of InfoSec Global and CipherInsights (a solution from Quantum Xchange) to consolidate leadership in quantum-safe security and cryptographic posture management. The combined offering will integrate cryptographic discovery, continuous risk monitoring, and automated certificate lifecycle management to help enterprises prepare for quantum-era threats. The company emphasized that the merged capabilities will address cryptographic complexity across modern infrastructures, including the detection of weak encryption protocols and compliance risks. The new suite of tools includes AgileSec Analytics for deep cryptographic asset discovery, AgileSec Agility for centralized cryptographic agility management without source code changes, and CipherInsights for passive, real-time traffic [...]

The European Union and Japan have formalized a new phase of collaboration in quantum science and technology with the signing of a Letter of Intent on May 13, 2025, in Tokyo. The agreement was signed by Henna Virkkunen, Executive Vice-President of the European Commission for Tech Sovereignty, Security and Democracy, and Minoru Kiuchi, Japan’s Minister of State for Science and Technology Policy, during the third EU-Japan Digital Partnership Council. The Letter of Intent strengthens the framework for cooperation between EU and Japanese stakeholders in quantum technologies, and builds on the broader EU–Japan Digital Partnership established in 2022. It follows joint statements [...]

Quantinuum and Al Rabban Capital have announced the formation of a Qatari joint venture aimed at accelerating the adoption of quantum computing in Qatar and the wider Gulf region. The initiative, backed by up to $1 billion in investment over 10 years, will focus on providing access to Quantinuum’s technology, co-developing region-specific quantum applications, and training a local quantum workforce. The venture was highlighted during the U.S. President’s state visit to Qatar and builds on Quantinuum’s prior collaboration with Hamad Bin Khalifa University and the Qatar Center for Quantum Computing (QC2). Strategic application areas include energy, materials discovery, precision medicine, financial [...]

Rigetti Computing has announced its Q1 2025 financial results. A summary of key financial metrics comparing Q1 2025 with Q4 2024 and the year-ago quarter of Q1 2024 is shown in the chart below. Financial Overview Rigetti reported $1.5 million in revenue for Q1 2025, marking a 36% decline from the previous quarter and a 52.5% year-over-year drop. This continues the downward trend in topline performance and reflects the company’s ongoing reliance on a small number of project-based contracts. Operating expenses rose to $22.1 million, up 13.2% from Q4 2024 and 22.0% from Q1 2024, driven by higher R&D expenditures. The [...]

IonQ has been in the news a lot recently with several announcement of partnerships, technical developments, and company acquisitions. You can see our most recent report covering their Q1 Financial Report in our article here and you can see a complete listing of all the recent stories we have posted about them by clicking here. So in order to get more insight into the companies strategy the Quantum Computing Report by GQI sent over a few questions over to Niccolo de Masi to better understand the thinking behind some of their recent moves. You can see our questions (labelled GQI) along [...]

SilQ Connect, a startup focused on distributed quantum computing, has closed its pre-seed funding round with backing from quantum-focused investors QV Studio, Quantacet, and Quantonation. The funding will support SilQ’s development of microwave-optical quantum interconnects for modular and scalable quantum systems. The company aims to enable utility-scale quantum computing by connecting modular processors into distributed architectures. This marks a critical step in advancing long-distance entanglement and scaling quantum computing systems beyond single-chip limitations. The investors include Quantonation, a global deep-tech VC; Quantacet, Quebec’s first quantum-focused fund; and QV Studio, a quantum venture studio that supports researcher-led startups. All three have supported [...]
