Insider Brief
- Horizon Quantum reported wider operating losses following its Nasdaq debut as it increased spending to build a hardware-agnostic quantum software platform and integrated testbed systems.
- The company expanded its technical capabilities through a 256-qubit system purchase from IonQ and collaborations with Alice & Bob and Alpine Quantum Technologies to support multi-hardware development and fault-tolerant software.
- Cash rose to $96.6 million after the business combination, while operating expenses increased due to hiring, public company costs, and continued investment in research, infrastructure, and industry engagement.
Horizon Quantum Holdings Ltd. reported wider losses and outlined a hardware-and-software integration strategy following its public listing, according to a company statement.
The Singapore-based company, which began trading on Nasdaq in March and is positioned as a developer platform for emerging quantum applications, posted a first-quarter operating loss of $6.5 million, up from $4.7 million a year earlier, according to the company’s news release. The increase reflects higher hiring and the costs associated with building out both its software platform and in-house quantum computing systems.
The results mark Horizon Quantum’s first earnings report as a public company after completing a business combination with special purpose acquisition company dMY Squared Technology Group. The deal closed March 19, with shares and warrants beginning trading the following day.
Net loss for the quarter narrowed to $3.6 million, or $0.09 per share, compared with a loss of $4.8 million, or $0.12 per share, in the same period last year. However, adjusted EBITDA — which is often used to show how a company’s core business is performing before financing choices, taxes and accounting rules come into play — widened to a $4.1 million loss from $1.8 million, reflecting underlying cost growth.
Cash and cash equivalents rose sharply to $96.6 million as of March 31, largely due to proceeds from the transaction and a related private investment in public equity, giving the company a larger cushion to fund expansion.
Horizon Quantum CEO and Founder Dr. Joe Fitzsimons said in the release: “Rapid advancement in quantum computing hardware coupled with recent breakthroughs in error correction may suggest the field is reaching an inflection point, with quantum advantage drawing nearer. We believe that the successful completion of our business combination with dMY Squared Technology Group, Inc., will allow us to significantly accelerate progress in building the software infrastructure to power quantum applications. We anticipate that the business combination has provided us with the financial runway required to support our strategic priorities for the foreseeable future, while enabling increased investments in R&D, allowing us to advance our integrated development environment, Triple Alpha, and push towards quantum advantage with the extension of our testbed. Together, we believe these initiatives will significantly strengthen our ability to unlock the full potential of quantum computing, positioning us to develop and grow revenue as the industry drives towards quantum advantage.”
Software Platform
Horizon Quantum is building what it describes as a full-stack software environment for quantum computing. Quantum computers use the principles of quantum mechanics to process information in ways that could eventually outperform classical computers on certain tasks.
At the center of that effort is its integrated development environment, known as Triple Alpha, according to the release. The platform is designed to allow developers to write and run quantum programs without needing to tailor code to a specific type of quantum hardware.
The system uses what the company calls a “Turing-complete” programming approach, meaning it can, in principle, express any computation that a traditional computer can perform, while also supporting quantum operations. It also includes tools to optimize programs and analyze how much computational resource they will require.
According to the release, Horizon Quantum continued to refine its programming language, Beryllium, during the quarter, aiming to make it more stable and feature-complete for broader developer use.
The company’s strategy reflects a broader industry trend: many firms are betting that software layers that can work across different quantum machines will be critical as the hardware landscape evolves.
Hardware Integration Strategy
Alongside software development, Horizon Quantum is investing heavily in physical systems, seeking tighter integration between code and hardware. It’s an approach that could be important for achieving so-called “quantum advantage,” where quantum computers outperform classical systems on practical problems, the team states.
The company operates its own quantum computing testbed, including a superconducting system called Ember-1, which it assembled and integrated at its Singapore headquarters earlier this year.
Unlike cloud-based access to quantum machines, this setup allows Horizon Quantum to directly control both the hardware and software stack. The company says this reduces latency — the delay between sending and executing instructions — and enables more complex, real-time operations.
In April, Horizon Quantum expanded that testbed by purchasing a 256-qubit trapped-ion quantum computer from IonQ. Trapped-ion systems use electrically charged atoms suspended in electromagnetic fields as quantum bits, or qubits, which are the basic units of quantum information.
By combining different hardware types — superconducting qubits and trapped-ion qubits — the company aims to build a multi-modality environment where developers can test software across architectures.
The release states that this approach is intended to “help ensure that their quantum applications remain useful—no matter which modality emerges as a frontrunner.”
Expanding the Ecosystem
Horizon Quantum also announced a series of collaborations aimed at linking its software platform to external hardware providers.
The company is working with IonQ as part of its hardware expansion, and separately with Alpine Quantum Technologies (AQT), a European trapped-ion provider, to integrate its processors with the Triple Alpha platform.
It has also partnered with Alice & Bob, a French quantum computing company focused on “cat qubits,” a type of qubit designed to reduce errors. The collaboration is intended to support the development of fault-tolerant quantum software — programs that can run reliably despite the high error rates that still affect quantum hardware.
These partnerships suggest Horizon Quantum is positioning itself as a bridge between hardware developers and software users, rather than focusing on a single proprietary system.
The company’s financial results reflect the cost of that strategy.
Research and development expenses were reported at $2.1 million, down from $3.3 million a year earlier, though the prior-year figure included a one-time share-based compensation charge. Excluding that, R&D spending rose sharply due to hiring and infrastructure costs.
Sales and marketing expenses increased 40% year over year, driven by greater industry engagement, while general and administrative expenses rose significantly as the company scaled operations and absorbed the costs of becoming a public entity.
Overall operating expenses climbed to $6.5 million for the quarter, underscoring the capital-intensive nature of building both software tools and quantum hardware capabilities.
Outlook Tied to Adoption
Horizon Quantum’s strategy reflects a long-term bet that developers will need more accessible tools to build useful quantum applications as the technology matures.
For now, the company remains in a pre-revenue or early-revenue stage typical of the quantum computing sector, where most firms are still investing heavily in research and infrastructure without clear near-term commercial returns.
The company’s growing cash position provides runway for continued development, but its widening adjusted losses highlight the challenge of scaling in a field that is still largely experimental.
According to the release, Horizon Quantum aims to “provide developers with the most direct path to broad quantum advantage,” though that milestone remains uncertain across the industry.
