Horizon Quantum Computing Pte. Ltd., the Singapore-based software infrastructure for quantum applications, announced Wednesday that it has completed the assembly and integration of a first quantum computer at its Singapore headquarters, and the system is now fully operational.
The firm said in a statement that assembled from components and operated directly by Horizon Quantum’s team, this system makes Horizon Quantum the first quantum software company to own and run a quantum computer.
Horizon Quantum believes that tight integration between hardware and software can offer the shortest path to useful quantum computing.
With the commissioning of its first quantum computer, the firm now has a testbed system over which it has full control of both the hardware and software stack.
This is expected to allow the company to integrate its execution stack directly with the electronic systems that directly control the quantum processor, helping to narrow the gap between the ideal theoretical model of quantum computation and its practical realization.
This work is anticipated to enhance the functionality of Triple Alpha, Horizon Quantum’s integrated development environment, and push the boundaries of seamless quantum application development.
Rather than relying on a single supplier, Horizon Quantum has assembled its first quantum system from best-in-class components, combining Maybell’s cryogenic platform, control electronics from Quantum Machines, and a Rigetti superconducting quantum processor.
This system is the first operational quantum computer in Horizon Quantum’s testbed facility, which has capacity to host multiple systems.
The system’s modular design enables the swapping in and out of additional control electronics and quantum processors, facilitating development across a diverse range of configurations and architectures.
This approach enables Horizon Quantum to test and integrate its software infrastructure with a variety of quantum hardware stacks, supporting the company’s goal of delivering the most capable hardware-agnostic development tools for quantum computers.
While this first quantum computer is based on superconducting qubits, Horizon Quantum aims to be operational on as many hardware platforms as possible, integrating with both cloud-based systems and quantum computers hosted in traditional data centers.
“Our focus at Horizon Quantum is on enabling developers to harness quantum computing to solve real-world problems that are not tractable with conventional computing. Achieving quantum advantage will require close coordination between the hardware and software layers,
“I strongly believe that by establishing our own hardware testbed we are placing the company in a compelling position to build a sophisticated hardware-agnostic development and execution stack that integrates tightly with hardware control systems and that will help unlock quantum advantage,” said Dr Joe Fitzsimons, Founder and Chief Executive Officer of Horizon Quantum.
Harry You, Chairman and Chief Executive Officer of dMY Squared Technology Group, Inc., the special purpose acquisition company that entered into a business combination agreement with Horizon Quantum in September 2025, said Horizon Quantum’s commissioning of its first in-house quantum computer is an impressive accomplishment and underscores the company’s leadership in building the software infrastructure that will power the next era of quantum computing.
“We are thrilled to support their continued execution and look forward to completing our business combination as Horizon accelerates toward its vision,” he added.
Horizon Quantum’s in-house quantum computer is expected to be made available via Triple Alpha.
