Horizon Quantum Acquires IonQ's 256-Qubit Trapped-Ion System

• •Horizon Quantum acquires a 256-qubit trapped-ion system from IonQ.
• •The system features 99.99% gate fidelity and all-to-all connectivity.
• •This acquisition expands Horizon Quantum's capabilities beyond superconducting systems.

Horizon Quantum Holdings Ltd. has entered into a strategic agreement with IonQ to acquire a 6th-generation, chip-based 256-qubit trapped-ion system. This acquisition is intended to enhance Horizon Quantum's hardware testbed, which currently relies on superconducting systems, by integrating a second, distinct hardware modality. The new system features all-to-all connectivity and microwave gate operations, achieving a gate fidelity of 99.99%, a record established by IonQ in 2025. The integration aims to advance Horizon Quantum's Triple Alpha software platform, allowing for more adaptive quantum programming capabilities. This collaboration is part of Horizon Quantum's broader strategy to provide a hardware-agnostic environment for developers. The agreement was finalized on March 31, 2026, following Horizon Quantum's recent listing on Nasdaq. The acquisition is expected to bridge the gap between existing hardware limitations and the utility scale required for complex applications. CEO Dr. Joe Fitzsimons emphasized the importance of this acquisition in achieving broad quantum advantage.
