Testbed
Horizon Quantum is the first quantum software company to operate its own quantum computer. In doing so, Horizon Quantum maintains full control over both quantum hardware and software stacks, providing a testbed for the integration of its software directly with hardware systems and allowing Horizon Quantum to develop real-time execution capabilities that go beyond what is possible over cloud connections. Having full control over the technology stack provides a critical advantage in accelerating the development of Horizon Quantum’s software infrastructure. Deeper software-hardware integration is also expected to play a central role in advancing experimentation with quantum error correction, fault tolerance, and other technologies critical to realizing practical quantum advantage. The testbed provides an ideal environment for developing and testing these capabilities. Horizon Quantum’s testbed currently houses a superconducting system, and the Company has announced its purchase of a second system based on trapped-ion technology to expand the testbed.
| ● | Testbed opens to first users: Ember-1, Horizon Quantum’s initial testbed system located at its Singapore headquarters and running since December 2025, has been opened to select first users. By enabling tighter hardware-software integration, the testbed environment provides efficient execution, extended capabilities, and faster iteration by accelerating the feedback loop. |
| ● | Triple Alpha on Ember-1 supports real-time execution of complete programs, eliminating the need for post-selected execution. The environment provides pulse- and gate-level access, supporting a broad range of quantum operations, experiments, and workflows. |
| ● | Second testbed system to be located at Horizon Quantum’s European headquarters: In June 2026, Horizon Quantum announced it would locate a 256-qubit trapped-ion system, anticipated to be one of the most advanced commercial quantum systems in the world, in Dublin, Ireland. This testbed adds a second, technologically distinct hardware modality, and with its expected qubit count and high gate fidelities, the system may be capable of solving some challenging computational problems. |
