425: Horizon Quantum Debuts Beryllium Quantum Programming Language

Horizon Quantum Computing announced the launch of Beryllium, a new hardware-agnostic, object-oriented language designed to make quantum programming more accessible.

Summary

• Horizon Quantum Computing Pte. Ltd. (Horizon) debuted Beryllium, a hardware-agnostic, high-level, object-oriented language for programming quantum computers.
• Beryllium is designed to empower developers by allowing them to create richer, higher-level structures from classical and quantum building blocks, shifting focus from low-level quantum processing to information structure.
• It aims to reduce the need for deep quantum expertise, making quantum software development more accessible to programmers without deep quantum expertise.
• Beryllium is the third of four abstraction layers in Horizon's ambitious plan to bridge classical and quantum programming.
• It will be accessible through Horizon's integrated development environment, Triple Alpha, alongside existing Turing-complete languages Helium and Hydrogen.
• Horizon will preview Beryllium at the Q2B Silicon Valley conference this week, also showcasing new pulse-level capabilities and direct execution of Hydrogen code on control systems hardware.
• The announcement is made in the context of Horizon's previously disclosed Business Combination Agreement dated September 9, 2025, with dMY Squared Technology Group, Inc.

• Costs related to the Business Combination.
• Changes in applicable laws and regulations or political and economic developments.
• Horizon Quantum may be adversely affected by other economic, business, and/or competitive factors.
• Horizon Quantum's estimates of expenses and profitability may not be accurate.
• The amount of redemptions by dMY public shareholders in connection with the Business Combination.
• Difficulties operating Horizon Quantum's quantum processor and the possibility that it does not provide the expected advantages.
• The ability of Horizon Quantum to integrate access to its quantum computing test bed within its Triple Alpha platform.
• The ability of Horizon's coding languages to provide additional abstraction compared to other quantum computing solutions.
• The ability to successfully or timely consummate the private placement of approximately $110 million of Holdco's Class A ordinary shares.
• The ability to recognize the benefits of the Side Letter, dated December 4, 2025, among Horizon Quantum, Holdco, dMY, and IonQ, Inc.
• Other risks and uncertainties included in the Risk Factors sections of dMY's Annual Report, other SEC filings, and the Registration Statement.

Future Outlook

Horizon Quantum expects Beryllium to provide higher levels of abstraction and utility to its users and be portable across any hardware system. The company also anticipates integrating access to its quantum computing testbed with its Triple Alpha system. Management believes enabling conventional software developers to harness quantum computers will be key to unlocking new applications.

Management Comments

• "At Horizon Quantum, we believe that enabling conventional software developers to harness quantum computers will be key to unlocking new applications." Dr. Joe Fitzsimons, founder and CEO.
• "We believe Beryllium is an important milestone, as we introduce the abstraction needed to bridge the gap between classical and quantum programming." Dr. Joe Fitzsimons, founder and CEO.

Industry Context

The debut of Beryllium positions Horizon Quantum Computing as a key player in developing accessible software infrastructure for the nascent quantum computing industry. By focusing on hardware-agnostic, high-level languages and abstraction, Horizon aims to lower the barrier to entry for conventional software developers, which is crucial for accelerating the adoption and application development in quantum computing. This move aligns with the broader industry trend of moving beyond low-level quantum hardware control towards more user-friendly programming paradigms to unlock quantum advantage.

Stakeholder Impact

• Shareholders (dMY and future Holdco): Potential for value creation through the business combination and successful product development, but also risks associated with the merger and market adoption.
• Developers: Beryllium aims to make quantum programming more accessible, potentially expanding the pool of developers who can work with quantum computers.
• Customers: Potential for new quantum applications and solutions enabled by easier programming.
• Employees: Continued growth and strategic development could offer opportunities, but also potential integration challenges post-merger.
• Investors (institutional/accredited): Opportunity to participate in the $110 million private placement.

Next Steps

• Horizon Quantum will preview Beryllium this week at Q2B Silicon Valley.
• Horizon Quantum Holdings Ltd. (Holdco) and Horizon Quantum will file a registration statement on Form F-4 relating to the Business Combination.
• dMY will mail a definitive proxy statement/prospectus to its shareholders after the Registration Statement is declared effective for voting on the Business Combination.
• The parties aim to successfully or timely consummate the private placement of approximately $110 million of Holdco's Class A ordinary shares.

Key Dates

Recommendation

While the debut of Beryllium is a positive technological advancement for Horizon Quantum, enhancing accessibility to quantum programming, the company is still in a pre-revenue or early-revenue stage, focused on infrastructure development. The ongoing business combination with dMY and the associated $110 million private placement introduce significant execution risks, including shareholder approval, integration challenges, and market adoption of quantum computing itself. Investors should hold to monitor the successful completion of the merger, the capital raise, and the market reception and adoption of Beryllium and Horizon's broader software stack before making further investment decisions.
