Singapore-based Horizon Quantum builds its own superconducting testbed, tightly integrating hardware and its Triple Alpha development environment.
Singapore’s Horizon Quantum Computing has announced that it has assembled and brought online its first in-house quantum computer, becoming what it calls the first quantum software company to both own and operate a full quantum system. The machine is installed at the company’s headquarters and is now fully operational as a private testbed.
Unlike most software-focused players, which access hardware exclusively via cloud providers, Horizon Quantum built the system from best-in-class components:
-
A cryogenic platform supplied by Maybell
-
Control electronics from Quantum Machines
-
A Rigetti superconducting quantum processor as the qubit core
The system is designed to be modular, allowing the team to swap in different control stacks and quantum processors. This gives Horizon Quantum the freedom to test its tools against a variety of architectures rather than being tied to a single vendor’s roadmap.
Horizon’s goal is to integrate this hardware deeply with Triple Alpha, its integrated development environment for quantum software. By owning the entire stack— from low-level control electronics to the developer tools— the company hopes to shrink the gap between theoretical algorithms and real hardware behavior, especially around timing, noise and error-mitigation strategies.
The company’s leadership sees this as a key step toward hardware-agnostic tools: software that can target different quantum devices but is informed by real, hands-on experience running code on physical qubits.
Conclusions:
-
Horizon Quantum is shifting from pure software to a software-plus-hardware model, treating its own quantum computer as a permanent test lab.
-
The modular design lets the firm experiment with multiple qubit technologies while still building a unified development and execution stack.
-
For developers, this could mean more realistic tooling, better debugging and tighter integration between classical orchestration and quantum operations.
-
Strategically, it suggests that future “software” companies in quantum may need direct hardware access to stay competitive.
