Honeywell is one of the companies you don’t naturally associate with frontier technologies like quantum computing. Honeywell’s quantum division Quantinuum was formerly known as Cambridge Quantum Computing. Might Honeywell be looking to capitalize on the buoyant quantum technology market? This market has seen meteoric rises in stock prices over the last few months.

Generative Quantum AI Framework
Quantinuum has unveiled a pioneering Generative Quantum AI framework (Gen QAI). It capitalizes on unique data generated by its advanced H2 quantum computer. This framework addresses complex challenges beyond the reach of classical computing.
The Rise of Quantinuum
Quantinuum is one of the largest employers in the quantum space. Across both hardware and software, it advances its Ion Trap quantum computers. It aims for new quantum volumes, which are metrics for comparing the performance of quantum computers. We don’t know the exact number of employees in the division. Still, it is estimated to be over 500 worldwide. Quantinuum is one of the largest dedicated entities that are exploring quantum computing.
Quantinuum is in a rapidly maturing market with companies like Rigetti, IonQ and Zapata AI. The latter pivoted away from Quantum and later failed. These companies made their way on the public market, not by IPO but via a SPAC. Investors have faced challenges over the years. This applies whether they held the SPAC company before the merger or afterward. It will not go unnoticed that considerable sums of investment flow into the quantum space.
Artificial Intelligence, Gen AI, and Quantum AI
AI is one of the hottest tickets around. Clamoring for the latest GPU to compute inferences on the latest LLM (Large Language Model) model is almost mimetic. The world demands bigger and faster processors. The need for new technologies that offer benefits beyond classical computing is evident.
Some chip makers have suffered due to the launch of DeepSeek. Yet, one trend is hard to argue against: the need for more “compute.” The world needs more energy. Similarly, compute capacity remains much the same. This remains true even with innovations like DeepSeek. It required less powerful GPUs for training its model. It also needed less power to provide inferences.
Beyond the swipes at Quantum Computing from NVIDIA’s CEO Jensen Huang, Quantum Computing has become markedly resilient. The debate continues about projected timelines for useful quantum computing. Meanwhile, actual companies are building better machines. These machines are supporting more qubits with better fidelity. More recently, Bill Gates has come out on nearer-term time horizons for useful or practical quantum computers.
Honeywell Restructure
Many will finally see the news that the conglomerate is embracing newer markets. The share price has barely moved in years. It has not benefited from the rise of AI or emerging technologies. The stock remains valued at around the same value as 4 years ago. Investors are not pricing in radical technologies like quantum, which Honeywell has in its stable.
Honeywell’s Three New Companies
Honeywell Automation
After completing the announced transactions, Honeywell Automation will lead the shift from automation to autonomy in the industrial sector. It expects $18 billion in revenue for 2024. The company will leverage its comprehensive portfolio of technologies. It will use software to drive productivity and digital transformation.
Honeywell Automation builds on its long-standing technological leadership. It leverages deep expertise and an extensive installed base. The company will serve a wide range of high-growth industries.
Honeywell Aerospace
Honeywell Aerospace provides technology and solutions for nearly all commercial and defense aircraft platforms. This includes propulsion, cockpit, navigation, and power systems. With $15 billion in expected revenue for 2024, the company will be one of the largest publicly traded aerospace suppliers. It leads to advancements in aviation through increased electrification and flight autonomy.
Advanced Materials
Honeywell’s Advanced Materials business will focus on sustainability. It will specialize in chemicals and materials. These include fluorine products, electronic materials, industrial fibers, and healthcare packaging. With nearly $4 billion in revenue, it offers innovative technologies like the low global warming Solstice® hydrofluoro-olefin (HFO). As a standalone company, it has a large domestic manufacturing base. It will gain from an optimized capital strategy. Additionally, it will have an attractive investment profile.
A New Direction for Quantinuum?
Honeywell’s decision to separate its business into standalone public companies by 2026 will likely influence Quantinuum’s strategic direction. This change will also affect its financial structure. Honeywell is a major shareholder of Quantinuum. It is also a financial backer. Quantinuum was formed through the merger of Honeywell Quantum Solutions and Cambridge Quantum in 2021.
The restructuring does not explicitly mention Quantinuum. However, Quantinuum is indirectly affected by its connection to Honeywell Automation. Changes in governance, investment priorities, and corporate strategy can impact.
The restructuring will also mean reassessing Honeywell’s long-term financial commitment to Quantinuum. If Honeywell decides to divest or reduce its stake, Quantinuum may need to seek alternative investors. They might also explore strategic partnerships to uphold their growth trajectory. The exact implications will become clearer. This clarity will occur as Honeywell finalizes the details of its corporate reorganization over the next two years.
Quantinuum IPO?
In July 2024, reports indicated that Honeywell was considering an initial public offering (IPO). They wanted an IPO for Quantinuum. They were seeking a valuation of approximately $10 billion. Recent reports do suggest that Honeywell is considering taking Quantinuum public. In January 2024, the company raised $300 million at a $5 billion pre‑money valuation. Bloomberg and other sources have analyzed the situation. They indicated that an IPO may aim for a valuation closer to $10 billion. Some estimates even suggest it could reach as high as $20 billion.
Honeywell “feels” rather like IBM. It, too, is a conglomerate. IBM has been aggressively pursuing quantum computing, getting its open source programming language, Qiskit, as the leader among quantum computer programmers. Will IBM also work to crystallize value from quantum computing by creating a separate division? Or will it prefer to keep the Halo effect showcasing IBM as an emerging technology leader?
No specific timeline has been established for a Quantinuum IPO. These developments suggest that Honeywell is actively exploring options to spin off Quantinuum. This move makes sense. There are strong market tailwinds. There has also been a rise in the number of quantum computing companies in the public markets.
Quantinuum has a strong technological foundation. It also has strategic industry partnerships. Furthermore, it has links to academics working in fields like QNLP with luminary scientists like Bob Coecke. The possibility of a high public valuation exists. An IPO could redefine Quantinuum’s growth trajectory. It could also transform the quantum industry as a whole. The company continues to achieve key milestones. It navigates its restructuring process. Investors and industry observers will keenly watch for the next steps toward public trading.
