QSENSATO, a spin-off from the University of Bari, has raised €500,000 ($560K USD) in pre-seed funding from LIFTT and Quantum Italia to accelerate the development and commercialization of integrated vapor cell quantum sensors. The company’s core technology is based on atomic-photonic chips that exploit quantum interference effects in rubidium vapor to achieve high sensitivity in measuring electric and magnetic fields. These quantum atomic sensors are miniaturized and optimized for portability, enabling use cases in medical diagnostics, GPS-free navigation, geophysics, and critical infrastructure monitoring. The funding will support the advancement of new prototypes, commercial scaling in Europe and the U.S., and the [...]

L&T-Cloudfiniti and QpiAI have announced a strategic partnership to deliver Quantum Computing as a Service (QCaaS), combining hyperscale cloud infrastructure with QpiAI’s superconducting quantum processors. The collaboration supports India's National Quantum Mission and will initially leverage Indus, QpiAI’s 25-qubit quantum computer, followed by a 256-qubit machine under development. QpiAI also disclosed plans for a future fault-tolerant platform with 100 logical qubits. These systems are vertically integrated with QpiAI's proprietary software stack, targeting near-term commercial and industrial workloads. The partnership will enable quantum computing services across domains such as finance, healthcare, and logistics. L&T-Cloudfiniti will host QpiAI’s hardware-accelerated workloads using its colocation [...]

Researchers from the Chinese Academy of Sciences have deployed the China Space Station Atom Interferometer (CSSAI), the first operational cold atom gyroscope in orbit. The system uses laser-cooled rubidium-87 atoms and atom interferometry to measure rotational and acceleration forces with high precision. Single-experiment results show a rotation resolution of 50 μrad/s and acceleration resolution of 1.0 μm/s². With integrated data, long-term rotation resolution improves to 17 μrad/s. These values were cross-validated with the station’s classical gyroscopes and found to match closely. The CSSAI payload, measuring 46×33×26 cm and operating at 75 W, applies a shearing interferometry technique with optimized “magic angle” [...]

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.
