Horizon Quantum Computing has finalized its business combination with dMY Squared Technology Group, Inc., a special purpose acquisition company (SPAC). Following shareholder approval on March 17, 2026, the combined entity will officially begin trading on the Nasdaq on March 20, 2026. The company’s Class A ordinary shares will list under the ticker symbol “HQ”, while its warrants will trade under “HQWWW”.
The transaction generated approximately $120 million in gross proceeds. Horizon Quantum intends to allocate these funds toward accelerating research and development, expanding its hardware testbed, and refining its Triple Alpha integrated development environment (IDE). The merger positions the Singapore-based firm to scale its software infrastructure at a time when breakthroughs in error correction and hardware scaling are bringing the industry closer to practical quantum advantage.
Horizon Quantum focuses on building a software layer that abstracts the complexities of quantum hardware, allowing developers to write programs without needing deep expertise in specific hardware modalities (such as superconducting, trapped ion, or photonic systems). This “hardware-agnostic” approach is designed to ensure the company’s tools remain relevant regardless of which hardware technology eventually dominates the market.
The company’s Triple Alpha platform allows for the creation of sophisticated quantum programs at multiple levels of abstraction. By bridging the gap between existing noisy hardware and future fault-tolerant systems, Horizon aims to empower developers to solve complex computational problems in fields like chemistry, logistics, and finance. CEO Dr. Joe Fitzsimons noted that the Nasdaq listing provides the necessary capital to lead the software infrastructure phase of the quantum industry.
