Quantinuum Expands Global Footprint to Singapore with the Establishment of a New R&D Centre

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. 

Official Statements
  • Dr. Rajeeb Hazra, President and CEO of Quantinuum, said: “We believe there are three pillars to a holistic strategy for building a sustainable quantum frontier: use cases, infrastructure, and workforce. Singapore provides an exceptional foundation for this approach, and we are proud to contribute our experience in ecosystem development as we build a leading quantum ecosystem together."
  • Dr. Marvin Lee, Country Leader for Quantinuum Singapore, who recently joined the company following senior appointments at A*STAR, EDB, and NRF, where he played a key role in shaping the National Quantum Strategy, said: “The new Centre will enable local talent and industry to work hands-on with quantum technologies, co-develop solutions aligned with national priorities, and support high-value jobs. We are committed to building long-term capability and resilience in Singapore’s digital economy."
  • Mrs. Josephine Teo, Minister for Digital Development and Information, a key advocate of the National Quantum Strategy, joined Quantinuum today as the Guest of Honour at the official opening of its new Centre, commemorated by a formal ribbon-cutting ceremony. She said: “Singapore aims to be a global hub for the development of algorithms and applications for quantum computers. We will tap on our strengths in sectors of potential application, such as finance, logistics, and pharmaceuticals. Doing so will not only benefit these industries in Singapore, but elsewhere in the world.” 
  • Mr. Pee Beng Kong, Executive Vice President, Singapore Economic Development Board, said: “Quantinuum’s expansion into Singapore marks an important step in translating quantum research into real-world industry applications. The Helios system and new R&D Centre will enable local companies and researchers to collaborate on next-generation solutions in areas such as drug discovery, materials innovation, and financial optimisation. This investment will deepen partnerships across our industry and research ecosystem and build high-value quantum capabilities from Singapore.”
  • Mr. Ling Keok Tong, Executive Director of the National Quantum Office, said: “Quantinuum's R&D Centre and the Helios deployment create opportunities for Singapore, giving our researchers hands-on access to advanced quantum hardware, and moves us closer to demonstrating real quantum advantage in drug discovery, portfolio optimisation, amongst others. This is a boost to our quantum research and talent development, as well as our efforts in building a robust quantum ecosystem.”

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 Selected by DARPA to Advance to Stage B of Quantum Benchmarking Initiative

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.
