Horizon Quantum

Where it fits in a quantum computer

Builds Triple Alpha, a hardware-agnostic development environment for quantum programs, and operates an on-site testbed in Singapore that combines a Rigetti Novera QPU, a Quantum Machines OPX1000 control system and a Maybell Big Fridge dilution refrigerator (about US$2.0 million invested per its 2025 20-F). It listed on Nasdaq on March 20, 2026 after its business combination with dMY Squared raised about $120 million of gross proceeds.

What the evidence establishes

Disclosed: Horizon’s 20-F describes Triple Alpha and the testbed’s components; its closing release gives the listing and proceeds.

An explicit quantum-computing product, design-in, supply role, program or partnership, such as a part sold for quantum computers or a named quantum-computer customer. For a maker, it means the company’s own quantum computers or processors. This does not establish revenue, market share, volumes or future sourcing.

Listed as a quantum-computer maker for its own systems, not as a supplier of the parts inside.

Keep in perspective

Specialist business exposure. This describes the breadth or role of the business; it is not an investment rating. A quantum-computing product, design-in or partnership does not by itself establish material quantum revenue, market share, or future returns.

Connections to the assembly

This company is mapped at sector level. The reviewed evidence does not establish a direct match to a specific illustrated part. Explore quantum computer makers for the broader relationship.
