Unveiling the first fully integrated and complete Quantum Monte Carlo Integration Engine
Quantinuum Scientists have created a full Quantum Monte Carlo Integration (QMCI) engine – with some evidence of quantum advantage
Cambridge, UK, September 12th, 2023 — Quantinuum, the world’s leading integrated quantum computing company has published full details of their complete Quantum Monte Carlo Integration (QMCI) engine. QMCI applies to problems that have no analytic solution, such as pricing financial derivatives or simulating the results of high-energy particle physics experiments and promises computational advances across business, energy, supply chain logistics and other sectors.
The QMCI tool, utilizing advanced quantum algorithms, will allow quantum computers to perform estimations more efficiently and accurately than equivalent classical tools, inferring an early-stage quantum advantage in areas such as derivative pricing, portfolio risk calculations and regulatory reporting. A white paper supporting the new tool reveals that QMCI benefits from a computational complexity advantage over classical MCI, and suggests the engine has the potential to provide quantum usefulness in its current form.
The white paper, A Modular Engine for Quantum Monte Carlo Integration, has been made available on arXiv, detailing, among other items, “the enhanced P-builder”, a tool for constructing quantum circuits representing commonplace computational methods used in finance. The white paper also proposes how users of the new tool could obtain quantum advantage without compromising statistical robustness in the ensuing estimates.
Ilyas Khan, Chief Product Officer of Quantinuum said “Quantinuum’s end-to-end QMCI engine – the first ever complete quantum solution, offers the prospect of an immediate boost to the productivity of users in at least two sectors: banking and financial institutions, and scientists who expect quantum computers to help them process the vast amounts of data generated in experimental fields such as high energy physics. Our QMCI engine is the culmination of years of work by our algorithms team, and highlights just how quantum computers will offer practical utility. Our modular approach also ‘future-proofs’ the engine as quantum computing hardware advances."
The engine has four modules - loading probability distributions and random processes as quantum circuits; programing a wide variety of financial calculations; programming different statistical quantities (e.g. mean, variance and others); and the estimation of quantum amplitude, which is the core source of computational advantage in QMCI. The engine features a resource mode, which precisely quantifies the exact quantum and classical resources needed for user-specified calculations – a feature which is essential for predicting when particular applications will enjoy quantum advantage. Thus, the paper reveals a direct line of sight to quantum advantage and concludes users will achieve useful benefits sooner still.
Dr. Steven Herbert said: “The QMCI engine taps into rapidly growing demand for tools that help global organizations in finance and other sectors explore and evaluate their route towards quantum advantage. Classical Monte Carlo integration is the preferred method in a range of computational areas where analytic solutions are unavailable and it is widely recognized that these methods will benefit from a quantum advantage. By taking a modular approach, we will equip those scientific and financial professionals with a platform that supports them flexibly through rapid technological advances in the years to come.”
The new white paper sets out the areas that stand to benefit from the development of QMCI, beyond finance, including achieving efficiencies in supply chain and logistics, energy production and transmission, and data-intensive fields of science such as solving the high-dimensional integrals in high-energy physics. It concludes that use cases such as estimation and forecasting can benefit from the new QMCI engine in its current form.
Banks and financial institutions are expected to increase investment in quantum computing capabilities from $80 million in 2022 to $19 billion in 2032, growing at a 10-year CAGR of 72%.

Washington, D.C. – September 8, 2026 – Quantinuum (Nasdaq: QNT), a leading quantum computing company, today announced it has finalized an agreement with the U.S. Department of Commerce’s CHIPS Research and Development Office for $100 million in federal funding deployed through the CHIPS and Science Act. The award, which follows a letter of intent announce in May, supports R&D and U.S. quantum semiconductor manufacturing capabilities needed to deploy large-scale, fault-tolerant trapped-ion quantum computers.
Quantinuum, which was the only company with a trapped-ion based architecture to be awarded CHIPS R&D funding, develops the world’s most accurate commercial1 computers with industry-leading error correction fidelity.2 The company leverages established semiconductor manufacturing processes to help ensure reliability, repeatability, and scalability of the company’s current and future quantum computers.
“This award is a validation of Quantinuum’s leadership in trapped-ion quantum computing," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Together with our domestic partners, we are building the technology and supply-chain foundation needed to scale fault-tolerant systems and strengthen America's leadership in this strategically important field.”
The award will support R&D that the company expects to help strengthen and diversify its supply chain, adding onshore partners GlobalFoundries and Monarch Quantum. GlobalFoundries will be one of several of Quantinuum’s foundries enlisted to fabricate its next-generation ion traps and other electronics, specifically focused on using 300mm wafer technology; Monarch Quantum plans to develop and manufacture scalable, reliable lasers and optical components required for Quantinuum’s trapped-ion systems.
“As quantum computing moves closer to commercial scale, manufacturing will be critical to unlocking its full potential,” said Tim Breen, CEO of GlobalFoundries. “GlobalFoundries is proud to partner with Quantinuum to help scale their trapped-ion technology. By bringing our expertise in high-volume, differentiated semiconductor manufacturing, we're helping create a path to more scalable, reliable quantum hardware and advancing the next generation of American innovation.”
“The road to large-scale, trapped-ion quantum computers relies on moving away from complex, sprawling optical setups to scalable, reliable integrated photonics engines," said Dr. Timothy Day, CEO of Monarch Quantum. "We are honored to expand our partnership with Quantinuum to advance their hardware roadmap and to help strengthen U.S. leadership in quantum computing manufacturing and supply chain resilience.”
Together, these efforts are intended to reduce system complexity and improve component robustness, reliability, and reproducibility, ultimately supporting the continued scaling of trapped-ion quantum computers, while strengthening domestic capability across critical photonics and semiconductor manufacturing.
