Cambridge Quantum recently announced it has made the source code for , its quantum software development kit, fully open to the quantum software community.
The move, which comes just months after the company began providing free access to , is expected to benefit software developers as well as Honeywell Quantum Solutions and other hardware providers.
Most of the programming languages or quantum software development kits available were designed initially to run on certain hardware platforms, creating compatibility issues. Software developers who wanted to test circuits or algorithms on different quantum technologies had to rewrite or tweak code to run on a new system.
Providing access to and its source code makes it easier for developers to do that.
鈥淯sers need only to focus on developing their quantum applications, not rewriting code around the idiosyncrasies of any particular hardware,鈥 said Dr. Ross Duncan, head of software at Cambridge Quantum.
And for Honeywell Quantum Solutions and other hardware providers, broadens access to their technologies by enabling developers to move more seamlessly between systems. The software development kit is optimized for each commercial hardware system, including Honeywell鈥檚 trapped-ion quantum computer.
鈥淲e want to make it as easy as possible for the quantum software community to run circuits and algorithms on our trapped-ion quantum computers,鈥 said Tony Uttley, president of Honeywell Quantum Solutions.聽鈥淭he System Model H1 technology is the highest performing quantum system available, and we want them to experience that.鈥
Honeywell Quantum Solutions and Cambridge Quantum have a long-standing history of partnering together for the benefit of end-customers. (The two entities announced in June they are seeking regulatory approval to combine to form a new company.)
"Having TKET fully open-sourced provides an incredible tool to the world鈥檚 quantum algorithm developers, including Honeywell," Uttley said.
鈥淥ur products and offerings have always been complementary and continue to be,鈥 he said. 鈥(Cambridge Quantum) has developed a suite of tools and programs that interface well with our hardware.鈥
If you have ever traveled to another country and tried plugging something in, you鈥檝e likely discovered the need for an adapter.聽Electrical outlets vary and the plug-ins used in the United States don't always work in Europe or other countries and vice versa.
The same is true with today鈥檚 early-stage quantum computers.聽Each technology has its own performance specifications, API (an interface that enables different computing systems to talk to one another), and compiler (a program that translates code written in one computing language to another).
is versatile.聽Developers can use it to create circuits or algorithms and also to serve as a universal connector or adapter between hardware and software platforms.
Cambridge Quantum has developed extensions, which are Python modules, for each commercial quantum hardware platform available. These extensions enable developers to code in Qiskit, Cirq, or another language and automatically adapt their circuits or algorithms to work on different quantum devices or simulators without having to tweak it themselves.
And now that is open source, developers can create their own extensions to the codebase and bridge between platforms.
夜色直播,聽the world鈥檚 largest integrated quantum company, pioneers powerful quantum computers and advanced software solutions. 夜色直播鈥檚 technology drives breakthroughs in materials discovery, cybersecurity, and next-gen quantum AI. With over 500 employees, including 370+ scientists and engineers, 夜色直播 leads the quantum computing revolution across continents.聽
I continue to be inspired by our team's pioneering efforts to redefine what鈥檚 possible through quantum computing. With more than 550 dedicated employees, we鈥檙e constantly pushing the boundaries to uncover meaningful applications for this transformative technology.
This week marked one of my proudest moments: the announcement of a joint venture with Al Rabban Capital to accelerate the commercial adoption of quantum technology in Qatar and the Gulf region. This partnership lays the groundwork for up to USD $1 billion in investment from Qatar over the next decade in 夜色直播鈥檚 state-of-the-art quantum technologies, co-development of quantum computing applications tailored to regional needs, and workforce development. This collaboration is a major step forward in our strategy to expand our commercial reach through long-term, strategic alliances that foster economic growth in both the U.S. and Qatar.
I had the unique opportunity to attend a business roundtable in Doha with President Trump, U.S. and Qatari policymakers, and other industry leaders. The conversation centered on the importance of U.S.-Qatari relations and the role of shared commercial interests in strengthening that bond.
A recurring theme was innovation in Artificial Intelligence (AI), reinforcing the role that hybrid quantum-classical systems will play in enhancing AI capabilities across sectors. By integrating quantum computing, AI, and high-performance computing, we can unlock powerful new use cases critical to economic growth and national security.聽
We also addressed the growing energy demands of AI-powered data centers. Quantum computing offers a potential path forward here, as well. Our H2-1 system has demonstrated an estimated 30,000x reduction in power consumption compared to classical supercomputers, making it a highly efficient tool for solving complex computational challenges.
What struck me most about the conversations in Qatar was the emphasis on cooperation over competition. While quantum is often framed as a race, our partnership with Al Rabban Capital underscores the value of cross-border collaboration. As I noted in a recent co-authored with Honeywell CEO Vimal Kapur, quantum computing isn鈥檛 just a technology鈥攊t鈥檚 a national capability. Countries that lead will shape how it is regulated, protected, and deployed. Our joint venture and this week鈥檚 dialogue reaffirm that both the U.S. and Qatar are taking the necessary first steps to lead in this space. Yet much work remains.
I believe we鈥檙e witnessing the emergence of a new kind of global alliance鈥攐ne rooted not just in trade, but in shared technological advancement. Quantum computing holds the promise to unlock innovative solutions that will tackle challenges that have long been beyond reach. Realizing that promise will require visionary leadership, global collaboration, and a bold commitment to shaping the future together.
I was honored to attend today鈥檚 roundtable during the President鈥檚 State Visit to Qatar and to see our announcement featured as part of that engagement. This milestone reflects a shared commitment by the U.S. and Qatar to strengthen strategic ties, spur bilateral investment in future-defining industries, and foster technological leadership and shared prosperity.聽
夜色直播鈥檚 expansion into the Gulf region, starting with Qatar, follows our successful growth in the U.S., U.K., Europe and Indo-Pacific. We will continue working across borders and sectors to accelerate the commercial adoption of quantum computing and realize quantum鈥檚 full potential鈥攆or the benefit of all!

Back in 2020, we to increase our Quantum Volume (QV), a measure of computational power, by 10x聽per year for 5 years.聽
Today, we鈥檙e pleased to share that we鈥檝e followed through on our commitment: Our System Model H2 has reached a Quantum Volume of 2虏鲁 = 8,388,608, proving not just that we always do what we say, but that our quantum computers are leading the world forward.聽
The QV benchmark was developed by IBM to represent a machine鈥檚 performance, accounting for things like qubit count, coherence times, qubit connectivity, and error rates. :听
鈥渢he higher the Quantum Volume, the higher the potential for exploring solutions to real world problems across industry, government, and research."
Our announcement today is precisely what sets us apart from the competition. No one else has been bold enough to make a similar promise on such a challenging metric 鈥 and no one else has ever completed a five-year goal like this.
We chose QV because we believe it鈥檚 a great metric. For starters, it鈥檚 not gameable, like other metrics in the ecosystem. Also, it brings together all the relevant metrics in the NISQ era for moving towards fault tolerance, such as gate fidelity and connectivity.聽
Our path to achieve a QV of over 8 million was led in part by Dr. Charlie Baldwin, who studied under the legendary Ivan H. Deutsch. Dr. Baldwin has made his name as a globally renowned expert in quantum hardware performance over the past decade, and it is because of his leadership that we don鈥檛 just claim to be the best, but that we can prove we are the best.聽
鈥
Alongside the world鈥檚 biggest quantum volume, we have the industry鈥檚 . To that point, the table below breaks down the leading commercial specs for each quantum computing architecture.聽
We鈥檝e never shied away from benchmarking our machines, because we know the results will be impressive. It is our provably world-leading performance that has enabled us to demonstrate:
As we look ahead to our next generation system, Helios, 夜色直播鈥檚 Senior Director of Engineering, Dr. Brian Neyenhuis, reflects: 鈥淲e finished our five-year commitment to Quantum Volume ahead of schedule, showing that we can do more than just maintain performance while increasing system size. We can improve performance while scaling.鈥澛
Helios鈥 performance will exceed that of our previous machines, meaning that 夜色直播 will continue to lead in performance while following through on our promises.聽
As the undisputed industry leader, we鈥檙e racing against no one other than ourselves to deliver higher performance and to better serve our customers.
At the heart of quantum computing鈥檚 promise lies the ability to solve problems that are fundamentally out of reach for classical computers. One of the most powerful ways to unlock that promise is through a novel approach we call Generative Quantum AI, or GenQAI. A key element of this approach is the (GQE).
GenQAI is based on a simple but powerful idea: combine the unique capabilities of quantum hardware with the flexibility and intelligence of AI. By using quantum systems to generate data, and then using AI to learn from and guide the generation of more data, we can create a powerful feedback loop that enables breakthroughs in diverse fields.
Unlike classical systems, our quantum processing unit (QPU) produces data that is extremely difficult, if not impossible, to generate classically. That gives us a unique edge: we鈥檙e not just feeding an AI more text from the internet; we鈥檙e giving it new and valuable data that can鈥檛 be obtained anywhere else.
One of the most compelling challenges in quantum chemistry and materials science is computing the properties of a molecule鈥檚 ground state. For any given molecule or material, the ground state is its lowest energy configuration. Understanding this state is essential for understanding molecular behavior and designing new drugs or materials.
The problem is that accurately computing this state for anything but the simplest systems is incredibly complicated. You cannot even do it by brute force鈥攖esting every possible state and measuring its energy鈥攂ecause 聽the number of quantum states grows as a double-exponential, making this an ineffective solution. This illustrates the need for an intelligent way to search for the ground state energy and other molecular properties.
That鈥檚 where GQE comes in. GQE is a methodology that uses data from our quantum computers to train a transformer. The transformer then proposes promising trial quantum circuits; ones likely to prepare states with low energy. You can think of it as an AI-guided search engine for ground states. The novelty is in how our transformer is trained from scratch using data generated on our hardware.
Here's how it works:
To test our system, we tackled a benchmark problem: finding the ground state energy of the hydrogen molecule (H鈧). This is a problem with a known solution, which allows us to verify that our setup works as intended. As a result, our GQE system successfully found the ground state to within chemical accuracy.
To our knowledge, we鈥檙e the first to solve this problem using a combination of a QPU and a transformer, marking the beginning of a new era in computational chemistry.
The idea of using a generative model guided by quantum measurements can be extended to a whole class of problems鈥攆rom to materials discovery, and potentially, even drug design.
By combining the power of quantum computing and AI we can unlock their unified full power. Our quantum processors can generate rich data that was previously unobtainable. Then, an AI can learn from that data. Together, they can tackle problems neither could solve alone.
This is just the beginning. We鈥檙e already looking at applying GQE to more complex molecules鈥攐nes that can鈥檛 currently be solved with existing methods, and we鈥檙e exploring how this methodology could be extended to real-world use cases. This opens many new doors in chemistry, and we are excited to see what comes next.
