en.Wedoany.com Reported - Horizon Quantum Holdings Ltd. and IonQ announced a strategic agreement, under which Horizon Quantum will procure one of IonQ's first sixth-generation chip-scale 256-qubit ion trap systems. According to a joint announcement released by Horizon Quantum and IonQ on April 9, 2026, this procurement is a core component of Horizon Quantum's expansion of its quantum hardware testbed. The agreement was finalized on March 31, 2026.

The announcement states that this 256-qubit system features a fully connected architecture and parallel operation design, utilizing microwave gate operations to achieve 99.99% gate fidelity. IonQ set a world record for two-qubit gate fidelity with this level of fidelity in October 2025. By integrating this ion trap system, Horizon Quantum will introduce a second hardware modality with a distinct technological pathway alongside its existing superconducting systems, becoming one of the few commercial entities globally operating a multi-modal quantum computing system.

The system will be integrated into Horizon Quantum's Triple Alpha software platform. The announcement notes that the integration aims to go beyond static circuit execution, enhancing real-time runtime capabilities, including universal control flow, dynamic memory allocation, and concurrent evaluation of classical and quantum functions. Dr. Joe Fitzsimons, Founder and CEO of Horizon Quantum, stated that incorporating high-fidelity ion trap qubits into the testbed is a foundational step in bridging the gap between current hardware limitations and the practical scale required for complex real-world applications.

IonQ continues to expand its IonQ Tempo product line to serve major cloud service providers such as Amazon Web Services and NVIDIA. Horizon Quantum recently completed its business combination with dMY Squared Technology Group and listed on the Nasdaq stock exchange.
