Testbed

Horizon Quantum is currently the only quantum software company to operate its own quantum computer. This gives Horizon Quantum 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. This represents a possible critical advantage in pursuing quantum advantage, where tight integration between hardware and software is expected to be critical to early success. With the acquisition of a second testbed system, Horizon Quantum intends to extend its hardware capabilities beyond solid state qubits to also encompass atom-based systems. The anticipated performance of the new system is expected to be an important resource for both in-house scientists and external Triple Alpha users pursuing quantum advantage.

●Initial testbed system - Industry-first hardware integration testbed: In January 2026, Horizon Quantum held the inauguration of its first quantum computer, Ember-1, having completed the assembly and integration of a fully operational, multi-vendor system at its Singapore headquarters. This system gives Horizon Quantum full control of both the quantum hardware and software stacks, allowing the company to integrate its software infrastructure directly with control systems, and avoiding latency issues that prevent fast feed-forward operations in remote settings.
●Second testbed system - tightly integrating Triple Alpha with a frontier quantum computing system: In April 2026, Horizon Quantum announced its purchase of IonQ’s 6th-generation, chip-based 256-qubit trapped-ion system. With this, Horizon Quantum plans to expand the capabilities of its quantum hardware testbed beyond its initial superconducting system with a second, technologically distinct hardware modality. This is anticipated to allow Horizon Quantum to expand support for trapped-ion systems in Triple Alpha and to enhance the real-time runtime capabilities within its execution infrastructure. Horizon Quantum expects to enable advanced execution functionality, including support for general control flow, dynamic memory allocation, and concurrent classical and quantum function evaluation, aiming to empower developers to go beyond the limits of static circuit execution and create adaptive, expressive quantum programs.
