Welcome back to This Week in Quantum — your weekly digest of the most important news from the world of quantum computing.
The week of May 10–16 was defined by institutional momentum: governments issuing RFIs with firm delivery dates, universities launching quantum degree programs, and one of the industry’s most prominent companies filing for a public market debut. The science kept pace too, with a new classical simulation record and a materials breakthrough. Let’s get into it.
Industry News
Quantinuum files S-1 with the SEC — IPO incoming
Quantinuum submitted a preliminary S-1 filing to the U.S. Securities and Exchange Commission, disclosing plans for an IPO on Nasdaq. The filing revealed net revenue of $30.9 million and a net loss of $192.6 million for 2025. Honeywell will retain significant influence post-IPO. The company’s product roadmap targets a processor with over one million physical qubits in the 2030+ timeframe.
Rigetti posts record Q1 2026 revenue and commits $100M to the UK
Rigetti Computing reported record Q1 2026 revenue of $4.4 million, driven by on-premises system shipments and the general availability of its 108-qubit system. The company also announced an investment of up to $100 million in the United Kingdom, where it plans to deploy a system exceeding 1,000 qubits.
Origin Quantum unveils Wukong-180
China’s Origin Quantum launched the Origin Wukong-180, a fourth-generation superconducting quantum computer with 180 qubits, integrated into its cloud platform for external access. The system has already been used in medicine, engineering, and physics research, and the company launched a program offering free computing time for academic research.
Xanadu announces Q1 2026 financial results
Xanadu reported strong Q1 2026 results, highlighted by its Nasdaq/TSX debut and a 304.3% year-over-year revenue increase to $2.83 million. The company is in active negotiations over $285 million in government funding to support further development of its photonic quantum computing platform.
NSF launches $1.5 billion X-Labs initiative
The U.S. National Science Foundation announced the X-Labs initiative, a $1.5 billion program targeting quantum and sensing technologies. The initiative signals a significant expansion of federal investment in quantum research infrastructure beyond the Department of Defense and DOE ecosystems.
Policy & Regulation
DOE issues RFI for a fault-tolerant quantum computer by 2028
The U.S. Department of Energy published a Request for Information seeking companies capable of delivering a fault-tolerant quantum computing system with 150–250 logical qubits by 2028. The system would be integrated into national laboratories to tackle complex scientific problems. The DOE is exploring Non-Recurring Engineering (NRE) funding and various partnership structures.
Purdue University launches a full Quantum Degrees Program
Purdue University introduced a multi-tiered Quantum Degrees Program offering undergraduate certificates, minors, and graduate-level qualifications, responding to growing demand for a skilled quantum workforce. The program is designed to bridge the gap between academic training and the industry’s technical hiring needs.
Research Highlights
JUPITER supercomputer simulates a full 50-qubit quantum computer
Scientists at the Jülich Supercomputing Centre, in collaboration with NVIDIA, achieved a world first: a complete simulation of a 50-qubit universal quantum computer on JUPITER, Europe’s first exascale supercomputer. The previous record stood at 48 qubits. The feat required approximately 2 petabytes of memory — only feasible on the world’s largest supercomputers — and sets a new benchmark for classical validation of quantum algorithms.
New quantum algorithm cracks an “impossible” materials problem
A quantum-inspired algorithm solved a computational problem that conventional supercomputers struggle to approach: simulating the quantum structure of quasicrystals, an extraordinarily complex class of materials. The method opens new paths for materials discovery and may have downstream implications for quantum hardware design.
Security Watch
Infleqtion launches Quantum Spectrum — atom-based RF sensing
Infleqtion unveiled Quantum Spectrum, a neutral-atom technology for radio frequency detection that offers broader spectrum awareness and stronger resistance to interference compared to traditional antenna-based systems. The company is already working on defense contracts in the U.S., UK, and Australia to transition the technology to field-deployable hardware. Infleqtion is targeting the quantum sensing market, projected to reach $31 billion by 2040.
