Infleqtion, in collaboration with JPMorgan Chase, has released an open-source quantum software library designed to accelerate research into more efficient quantum error correction methods. The library, called qLDPC, implements advanced fault-tolerant coding schemes that can potentially reduce the number of physical qubits needed per logical qubit by a factor of 10 to 100, depending on the code. This breakthrough addresses one of the most persistent bottlenecks in quantum computing—excessive qubit overhead for achieving error tolerance. The qLDPC library supports error correction schemes particularly well suited to Infleqtion’s neutral atom-based quantum computing hardware, which offers programmable qubit layouts. This hardware-software co-design approach [...]

Tel‑Aviv‑based Classiq Technologies, a provider of high‑level quantum algorithm design and synthesis tools, has raised US $110 million in a Series C financing that the company says is the largest single funding round for a quantum‑software vendor to date. The new capital brings Classiq’s total funding to US $173 million and extends its runway well into the next phase of noisy‑intermediate‑scale‑quantum (NISQ) commercialisation. Use of proceeds. Classiq will scale go‑to‑market and customer‑success teams, grow its R&D head‑count, and deepen participation in national quantum‑computing programmes across Asia, the United States and Europe. “We are building the Microsoft of quantum computing,” said co‑founder & CEO Nir Minerbi, pointing to the [...]

There has been a lot of recent political action in the United States to provide support for the advancement of quantum tech. We cover them here. The Quantum Sandbox for Near-Term Applications Act has been introduced in both the U.S. Senate (S.1344) by Marsha Blackburn (R-TN) and Ben Luján (D-TN) as well as in the U.S. House (H.R.3220) by Representatives Jay Obernolte (R-CA), Haley Stevens (D-MI), Randy Weber (R-TX), and Richard Hudson (R-NC). The bill aims to increase quantum technology commercial advancement through the creation of a quantum sandbox program. This program allows government and industry partners to come together through the [...]

Celebrating Scientific Discovery with Music, Art and Poetry Overview During its annual March meeting, APS celebrated the International Year of Quantum Science and Technology with a week-long Quantum Fest. The two directors of the event combined their scientific expertise with their love for art to tell stories of quantum physics. Smitha Vishveshwara, PhD and Marilena Longobardi, PhD, brought acrobats, musicians and scientists together on stage to display the wonder and power of nature from a subatomic to a cosmic scale. In this episode, host Veronica Combs and the two physicists discuss how the event came together and how hands-on experiences reveal [...]

PsiQuantum has selected Linde Engineering to design and deliver a large cryogenic cooling plant for its first utility-scale quantum computer, to be constructed in Brisbane, Australia. The system will cool PsiQuantum’s Omega photonic quantum chips, which are housed in cryogenic cabinets operating at approximately 4 Kelvin (-269 °C, -452 °F). The photonic qubit architecture allows for higher operating temperatures than matter-based systems, enabling more efficient scaling using standard optical fiber interconnects. The cryogenic plant will support tens of thousands of quantum chips and is among the largest built for this purpose. Linde Engineering brings experience from over 500 cryogenic plant installations across [...]

Equal1, developer of Ireland’s first quantum computer Bell-1, has signed a Memorandum of Understanding (MoU) with CeADAR, Ireland’s Centre for Applied AI, to accelerate the national Quantum-AI infrastructure. The partnership targets joint development of funded R&D proposals and aims to build a framework supporting Irish business and academic adoption of hybrid quantum-AI systems. Bell-1 uses a silicon-based architecture designed for scalability and cost-efficiency, signaling a transition from research prototypes to deployable systems. The collaboration will focus on integrating Equal1’s compact quantum servers with AI workflows, leveraging CeADAR’s enterprise outreach to promote adoption. Equal1’s approach, termed “Quantum Computing 2.0,” features a monolithic [...]

Anyon Technologies (Singapore) and YQuantum LLC (Switzerland) have announced a strategic partnership to co-develop scalable superconducting quantum computing systems and establish a European-based quantum testbed. The collaboration aims to integrate Anyon’s quantum computing hardware with YQuantum’s cryogenic signal routing and filtering technologies, enabling next-generation quantum systems with enhanced modularity and scalability. The initiative reflects a broader ambition to build a global quantum supply chain, strengthening quantum capabilities in both Asia and Europe. With mutual roots in research institutions such as Caltech, UC Berkeley, and ETH Zurich, both companies bring complementary expertise to support hardware innovation and industrial deployment. The planned testbed [...]

Alice & Bob has announced the construction of a $50 million quantum hardware facility in Paris, featuring a 4,000 m² chip development lab with a nanofabrication cleanroom and infrastructure to support its next-generation QPU lines: Lithium, Beryllium, and Graphene. The facility will include a cryostat farm housing 20 dilution refrigerators to enable parallel experimentation and development, with a dedicated section for testing Graphene, a 100-logical-qubit machine scheduled for 2030. The lab is funded by the company’s recent $103 million Series B. The site will integrate systems from Quantum Machines and Bluefors, who will provide quantum control electronics and cryogenic infrastructure, respectively. [...]

Maybell Quantum has signed an agreement with Interlune, a U.S. space resources company, to become its first commercial customer for lunar-sourced helium-3, a critical input for dilution refrigerators used in quantum computing. Under the deal, Maybell will receive thousands of liters of helium-3 annually between 2029 and 2035 to support the cooling requirements of its cryogenic platforms. These systems, including the company’s high-density “Big Fridge,” enable quantum processors to operate below 10 millikelvin and have already demonstrated threefold improvements in qubit support within one-tenth the volume of competing systems. On the same day, Interlune announced a groundbreaking agreement with the U.S. [...]

Oxford Ionics has released a detailed development roadmap for its trapped-ion quantum computing platform, outlining a three-phase strategy—Foundation, Enterprise-grade, and Value at scale—designed to scale its systems from current deployments of 16–64 qubits to over 10,000 physical qubits, ultimately enabling millions of logical qubits. The roadmap is anchored not only on qubit count but on achieving industry-leading physical error rates of 10-4 and below, aiming to support practical, high-fidelity quantum computation in real-world applications. In the Foundation phase, Oxford Ionics is deploying QPUs featuring 16–64 qubits with 99.99% fidelity and all-to-all connectivity, enabling complex algorithm execution without immediate error correction.
