Future Outlook

Horizon Quantum expects its in-house quantum computer to enhance the functionality of its Triple Alpha integrated development environment and aid in building a sophisticated hardware-agnostic development and execution stack. This is anticipated to help unlock quantum advantage by integrating tightly with hardware control systems. The system is expected to be made available via Triple Alpha, and the company aims to be operational on as many hardware platforms as possible, including cloud-based and traditional data center systems.

Management Comments

• "Our focus at Horizon Quantum is on enabling developers to harness quantum computing to solve real-world problems that are not tractable with conventional computing. Achieving quantum advantage will require close coordination between the hardware and software layers. I strongly believe that by establishing our own hardware testbed we are placing the company in a compelling position to build a sophisticated hardware-agnostic development and execution stack that integrates tightly with hardware control systems and that will help unlock quantum advantage." Dr. Joe Fitzsimons, founder and CEO of Horizon Quantum.
• "Horizon Quantum's commissioning of its first in-house quantum computer is an impressive accomplishment and underscores the company's leadership in building the software infrastructure that will power the next era of quantum computing. We are thrilled to support their continued execution and look forward to completing our business combination as Horizon accelerates toward its vision." Harry You, Chairman and CEO of dMY Squared Technology Group, Inc.

Industry Context

This announcement positions Horizon Quantum as a unique player in the quantum computing industry by being a software-focused company that also owns and operates its own quantum hardware. This strategy of tight hardware-software integration aims to accelerate the path to "quantum advantage," differentiating it from companies that solely focus on either hardware or software, or rely entirely on third-party cloud access. It suggests a move towards more integrated solutions in the nascent quantum computing market, potentially setting a new standard for software development in the sector.

Comparison to Industry Standards

• Horizon Quantum is the first quantum software company to own and operate a quantum computer, distinguishing it from other quantum software providers that typically rely on third-party hardware access.
• The system combines components from Maybell (cryogenic platform), Quantum Machines (control electronics), and Rigetti (superconducting quantum processor), indicating a best-of-breed, modular approach rather than relying on a single vendor's integrated stack.
• This modular design contrasts with fully vertically integrated quantum hardware companies, allowing for greater flexibility in testing and integrating with diverse quantum hardware stacks and supporting hardware-agnostic development.

Legal Proceedings

• The outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination and the Business Combination Agreement is a risk factor.

Stakeholder Impact

• Shareholders of dMY Squared Technology Group, Inc. will vote on the Business Combination and an Extension, with potential for value creation from the merger with Horizon Quantum.
• Employees of Horizon Quantum Computing are directly involved in the assembly and operation of the quantum computer, indicating continued strategic development and innovation.
• Customers and developers using Horizon Quantum's Triple Alpha integrated development environment are expected to benefit from enhanced functionality and access to the in-house quantum computer, enabling more seamless quantum application development.
• Investors are provided with important information regarding the Business Combination and Horizon's technological progress, which may influence investment decisions.

Next Steps

• Holdco and Horizon will file a registration statement on Form F-4, including a preliminary proxy statement of dMY and a preliminary prospectus of Holdco.
• After the Registration Statement is declared effective, dMY will mail a definitive proxy statement/prospectus to its shareholders for voting on the Business Combination.
• A special meeting of dMY shareholders will be held to vote on the Business Combination.
• Horizon Quantum aims to be operational on as many hardware platforms as possible, integrating with cloud-based systems and quantum computers hosted in traditional data centers.
• The in-house quantum computer is expected to be made available via Triple Alpha.

Key Dates

Recommendation

While the completion of Horizon Quantum's first quantum computer is a significant technical milestone and a positive development, the overall investment decision is tied to the pending business combination with dMY Squared Technology Group. The filing itself is an update on a technical achievement rather than a comprehensive financial report. Investors should hold pending further details from the Form F-4 registration statement, which will provide more comprehensive financial, operational, and risk information related to the combined entity, allowing for a more informed assessment of valuation and future prospects. The quantum computing sector is highly speculative, and while this is a good step, it doesn't immediately warrant a 'buy' without deeper financial analysis of the combined entity.
