The R&D Centre, together with the planned deployment of a Quantinuum Helios system in Singapore, aims to accelerate industrial collaboration across pharma, materials and finance, while bolstering the local quantum ecosystem and workforce
March 11, 2026 – Singapore – Quantinuum, a leading quantum computing company, today announced the establishment of a new R&D and Operations Centre (the “Centre”) in Singapore, marking its formal expansion into Singapore. This important development will enable Quantinuum to deepen collaboration with the nation’s research and industrial ecosystem, together with the company’s plan to deploy its Helios quantum computer in Singapore later this year.
Singapore’s early investment in quantum has positioned the nation to capture value as quantum systems move toward real-world use. In his national budget speech last month, Prime Minister Mr. Lawrence Wong highlighted Quantinuum as an industry leader, emphasizing that Helios will enable Singaporean researchers and companies to work on meaningful projects.
The new Centre will bring together Quantinuum staff with local researchers and industry partners to co-develop commercially relevant solutions across pharma, materials science, finance, and other sectors. It will also serve to help advance Singapore’s national priorities under its National Quantum Strategy by strengthening long-term R&D capabilities and workforce development, helping position Singapore as a global hub for quantum technology.
The Centre’s establishment is supported by the Singapore Economic Development Board (EDB) and builds on Quantinuum’s close partnership with Singapore’s National Quantum Office (NQO) through the National Quantum Computing Hub. The National Quantum Strategy is developed and implemented by NQO, which is hosted in the Agency for Science, Technology and Research (A*STAR), and funded by the National Research Foundation (NRF).
As part of its commitment to developing a robust local ecosystem and support for innovation across the full quantum value chain, Quantinuum is collaborating with pioneering startups in Singapore, including Entropica, which accesses Quantinuum systems through its Startup Partner Program, and Squareroot8, with whom Quantinuum signed a Memorandum of Understanding today to co-develop quantum communications applications.
The new Centre represents an important step in Quantinuum’s international expansion and its commitment to collaborating with partners in key innovation hubs. Quantinuum looks forward to continued collaboration with Singapore’s research and industry ecosystem to advance the development and application of quantum technologies.
Quantinuum is a leading quantum computing company offering a full-stack platform designed to make quantum computing deployable in real-world environments. The company has commercially deployed multiple generations of quantum systems built on the well-established QCCD architecture, which it has implemented with novel designs and capabilities to achieve the industry’s highest accuracy levels based on average two-qubit gate fidelity1. Quantinuum has active engagements with market leaders across pharmaceuticals, material science, financial services, and government and industrial markets.
The company has a global workforce of approximately 700 employees, including top scientists and researchers. Over 70% of its technology team hold PhDs. Quantinuum’s headquarters is in Broomfield, Colorado, with additional facilities across the United States, United Kingdom, Germany, Japan, and Singapore.

With the industry's most advanced quantum systems and proven ability to scale, Quantinuum is on track to deliver utility-scale quantum computing by early 2030s
November 6, 2025 – Broomfield, CO – Quantinuum, the world leader in quantum computing, has been selected by the Defense Advanced Research Projects Agency (DARPA) as a contractor to advance to Stage B of DARPA’s Quantum Benchmarking Initiative (QBI).
DARPA is using QBI to evaluate the technical likelihood that a utility scale quantum computer will be available no later than 2033. A multi-stage program, Stage B follows a six-month Stage A effort in which Quantinuum developed and delivered a detailed concept design for a utility scale system called “Lumos.”
Last year, Quantinuum released its public roadmap through the end of the decade with Apollo—a universal, fully fault-tolerant quantum computer—scheduled for launch in 2029. Lumos is a new addition to the roadmap as Quantinuum outlines plans to develop increasingly larger systems into the 2030s.
“This selection recognizes the strength and maturity of our roadmap and the work our teams have already delivered,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Lumos extends our roadmap into the next decade and gives DARPA a concrete, de-risked path for achieving utility-scale quantum computing by 2033. We look forward to partnering with DARPA and our ecosystem partners to advance this important national objective.”
Stage B will be a year-long, performance-based evaluation by DARPA’s Test and Evaluation team in which Quantinuum will develop a detailed R&D roadmap for Lumos to validate technical assumptions, verification methods, and scaling plans to meet the 2033 objective.
Yesterday, Quantinuum deployed its latest generation system, “Helios,” on schedule with its roadmap. With the highest fidelity physical qubits and logical qubits of any commercial system, and a next-generation software stack featuring a modern, high-level programming language, Helios is designed to accelerate quantum computing adoption. The system has already been used to simulate high-temperature superconductivity and magnetism at unprecedented scales—two applications with relevance to critical, industrial utility.
Quantinuum is the world leader in quantum computing. The company’s quantum systems deliver the highest performance across all industry benchmarks. Quantinuum’s over 630 employees, including 370+ scientists and engineers, across the US, UK, Germany, and Japan, are driving the quantum computing revolution.
