Insider Brief
- Horizon Quantum and Quantum Machines have announced a collaboration to develop embedded calibration technologies for Horizon Quantum’s Ember-1 superconducting quantum computer testbed.
- The companies will use Quantum Machines’ OPX1000 control system and orchestration platform to create calibration routines designed to improve system uptime and operational stability.
- The collaboration aims to reduce reliance on lengthy calibration cycles by enabling more frequent parameter updates during quantum system operation.
Press release – Horizon Quantum Computing Pte. Ltd., the wholly-owned subsidiary of Horizon Quantum Holdings Ltd. (Nasdaq: HQ) (“Horizon Quantum”), a pioneer of software infrastructure for quantum applications and Q.M Technologies Ltd. (“Quantum Machines” or QM”), a leading provider of advanced hybrid quantum-classical control solutions, today announced a strategic collaboration to support the development of more robust, efficient quantum systems.
Through the collaboration, Horizon Quantum will leverage QM’s industry-leading orchestration platform for quantum control, alongside QM’s engineering expertise, to develop embedded calibration technologies for Horizon Quantum’s first in-house hardware testbed system Ember-1, a modular superconducting quantum computer. This collaboration aims to accelerate the delivery of more reliable, continuously operating quantum systems.
Accurate calibration determines the fidelity of a quantum system; however, a full calibration routine is a time-consuming process. As quantum computers continue to scale, maintaining accurate calibration without interrupting system operation has become an increasingly important challenge.
In collaboration with Quantum Machines, Horizon Quantum intends to develop an embedded calibration framework that enables lightweight calibration routines to be executed as part of normal system operation, reducing reliance on lengthy full-system calibration cycles. By updating the system parameters more frequently, this process will be designed to reduce downtime, improve operational stability, and maintain high-performance operation over extended runtimes.
To support this development, Horizon Quantum will leverage QM’s OPX1000 control system—the system currently used in Ember-1. By improving Ember-1’s uptime, this collaboration is expected to increase the amount of access time available for Triple Alpha users on the system. It also aims to demonstrate the capabilities of QM’s control technology in a real-world quantum computing environment.
The collaboration reflects both companies’ shared commitment to advancing practical quantum computing by combining best-in-class quantum software and control technologies that enable customers to build scalable, high-performance quantum systems.
“Improved calibration routines are crucial for enabling real-world applications of quantum computing,” said Dr. Joe Fitzsimons, CEO of Horizon Quantum. “By bringing together Horizon Quantum’s expertise in quantum software and Quantum Machines’ expertise in quantum control, I believe we can develop lightweight calibration routines that increase uptime and improve the reliability of our testbed system. This strategic collaboration provides us with an opportunity to contribute to the development of more stable, performant quantum systems, and because our hardware testbed integrates Horizon Quantum’s software infrastructure with a quantum computer containing a Quantum Machines OPX1000 control system, it provides an ideal environment for this endeavor.”
“The future of quantum computing depends on our ability to operate increasingly complex systems reliably and at scale,” said Dr. Itamar Sivan, CEO of Quantum Machines. “We are excited to collaborate with Horizon Quantum on technologies that bring calibration closer to real-time operation, helping unlock more productive quantum systems and accelerating the path toward practical quantum computing.”
