Welcome to Quantinuum, the combination of Honeywell Quantum Solutions and Cambridge Quantum

In a long-anticipated tie-up, a new Quantum Computing company has emerged from the Cambridge (UK) based Cambridge Quantum and the US-based Tech Giant Honeywell. It is a move that will likely further excite the marketplace which has seen the IonQ get listed and multiple technology milestones from the likes of IBM and Google. The new company has 400 staff members and will be one of the largest dedicated Quantum Computing companies on the planet.

“Quantinuum is now the largest and most advanced integrated quantum computing company in the world,”

Ilyas Khan, CEO of the new company and founder of Cambridge Quantum.

Two leading companies in the quantum computing industry have combined to create Quantinuum with the aim to accelerate quantum computing build innovation of quantum technologies in a platform-agnostic way that can deliver real-world quantum-enabled solutions.

Cambridge Quantum works on a number of fronts such as quantum software (TKET), operating systems, and cybersecurity, but is well known for its innovative work in the development of QNLP (Quantum NLP). Honeywell Quantum Solutions has produced some of the most performant quantum hardware. Honeywell’s technology is based on trapped-ion technologies (similar to IonQ) and on the 30th of November 2021 announced the new company, now called Quantinuum.

“By uniting the best-in-class quantum software available with the highest performing hardware available, we are uniquely positioned to bring real quantum computing products and solutions to large, high-growth markets in the near term, the medium term and the longer term as quantum computers scale in capacity and quality. We are science led and enterprise driven, and our scale and global presence in this most critical of technologies will provide leadership in each of the key areas that constitute the ‘must haves’ for quantum computing to deliver real-world solutions to all our customers and partners.”

Ilyas Khan, CEO of the new company and founder of Cambridge Quantum.

Quantinuum will launch a quantum cybersecurity product in December 2021, and later in 2022, an enterprise software package that applies quantum computing to solve complex scientific problems in pharmaceuticals, materials science, speciality chemicals and agrochemicals. It will also announce major upgrades to the System Model H1 hardware technologies Powered by Honeywell, which reportedly has the highest measured quantum volume (a measure pioneered by IBM) as well as industry breakthroughs that reduce errors on the path to fault-tolerant quantum systems.

“I am thrilled to help lead our new company, which will positively change the world through the application of quantum computing. Our scientists continue to work hard to develop the best quantum software and hardware technologies available and I am excited to be able to offer these to customers on an ongoing basis,”

Tony Uttley COO of Quantinuum


It is six months after Honeywell announced that Honeywell Quantum Solutions, their quantum computing division, would separate from the company and join forces with Cambridge Quantum. In terms of shareholders, Honeywell will initially be the largest shareholder of Quantinuum, with an approximately 54% ownership stake in the new company and has invested nearly $300 million in the new venture, providing sufficient capitalisation to grow and build the business. Interestingly Honeywell will also be a supplier of Quantinuum, supporting the manufacturing process for the company’s proprietary ion-traps, as well as a customer of Quantinuum on various projects across its business units. Fout hundred people are already employed by the venture and there are multiple offices around the globe (United Kingdom, United States, Japan and Germany).

“The next few weeks and months are going to be extremely active for Quantinuum, as we increase the pace in deriving unique value from today’s quantum computers especially in cybersecurity. However, in addition to cybersecurity, our products will include solutions for drug discovery and drug delivery, materials science, finance, natural language processing, as well as optimisation, pattern recognition and supply chain and logistics management.”
