Horizon Quantum discusses its planned business combination with dMY Squared Technology Group and how its new quantum computer supports future growth. CEO Joseph Fitzsimons explains that the company has invested about $2.6 million to build a hardware testbed in Singapore, giving it full control over both software and hardware so its Triple Alpha tools can compile directly to its own quantum assembly language.
He notes the system is already fostering new software and hardware skills and supporting team expansion in Singapore and Ireland, although specific headcount targets are not disclosed. Horizon Quantum expects real-world quantum applications to emerge in roughly two to four years, with potential impact in chemistry, pharma, finance and AI. The filing also highlights a previously announced Business Combination and an approximately $110 million PIPE financing for Holdco, along with detailed risk and forward-looking statements disclosures.
Horizon Quantum Computing describes how it has built its first in‑house quantum computer in Singapore as a hardware testbed for its Triple Alpha software tools. The company says it invested about $2.6 million in constructing the processor and surrounding test electronics so developers can compile programs from its languages down to a proprietary quantum assembly language and run them both on cloud systems and on Horizon’s own hardware.
Management explains that operating its own system helps deepen local skills across software, hardware integration and operations, and supports team expansion in Singapore and Ireland, though no headcount targets are disclosed. The CEO notes industry expert surveys that place commercially meaningful quantum applications roughly two to four years away, with potential uses in areas like chemistry, pharma, finance and AI.
The communication also references Horizon Quantum’s previously announced business combination with dMY Squared Technology Group via Holdco and an associated PIPE financing of approximately $110 million of Class A ordinary shares, which remain subject to shareholder approvals, regulatory clearances and other closing conditions.
Horizon Quantum discusses its role in quantum computing and its pending merger with dMY Squared Technology Group, a blank-check company. CEO Joe Fitzsimons explains that Horizon builds hardware-agnostic quantum software infrastructure, including the Triple Alpha development environment and the new Beryllium object-oriented language, to let developers program quantum computers more like classical systems and target multiple hardware platforms.
The discussion highlights recent progress in quantum error correction, the diversity of hardware modalities, and Horizon’s AWS-like usage-based business model for cloud access, with on-prem models likened to Windows Server or VMware. The text notes a previously announced business combination among Horizon Quantum, Horizon Quantum Holdings Ltd. and dMY Squared, supported by a registration statement on Form F-4 and a contemplated private placement of approximately $110 million of Holdco Class A ordinary shares, with shareholders to receive a proxy statement/prospectus before voting at a special meeting.
Horizon Quantum Computing and dMY Squared are advancing a previously announced business combination supported by an approximately $110 million PIPE financing for Holdco’s Class A ordinary shares. This communication shares a detailed interview with Horizon’s CEO, who explains the company’s strategy to build a hardware-agnostic quantum software stack that turns emerging quantum devices into practical, programmable computers. Horizon’s Triple Alpha environment and its new object-oriented language, Beryllium, aim to let mainstream developers write quantum programs at higher levels of abstraction while targeting multiple hardware modalities such as superconducting, trapped-ion, photonic, and neutral-atom systems.
The discussion emphasizes that quantum hardware has recently reached key milestones in error correction and scale, but that software remains critical for delivering real-world applications in fields like chemistry, finance, AI, and energy. Horizon outlines a cloud-style, usage-based business model similar to major infrastructure software providers, with long-term potential for high-margin, software-like economics. The filing also highlights extensive risk factors, including the possibility the business combination or PIPE could be terminated, shareholder redemptions, listing uncertainties, technical challenges operating Horizon’s quantum processor, and the many conditions that must be satisfied before the deal can close.
dMY Squared Technology Group, Inc. furnished an investor presentation related to its proposed business combination with Horizon Quantum Computing Pte. Ltd. and Horizon Quantum Holdings Pte. Ltd.
