Singapore-based software firm Horizon Quantum has deployed what it says is the city-state’s first commercial quantum computer operated by a private company. The system, now fully operational, integrates components from suppliers including Maybell Quantum, Quantum Machines, and Rigetti Computing. Founded in 2018, Horizon Quantum describes itself as the first pure-play quantum software company to own and run its own quantum computer, marking a strategic shift from software-only development to full-stack integration.
The deployment is intended to support the company’s push toward commercially viable quantum applications across sectors such as pharmaceuticals and finance, by giving its engineering teams direct control over hardware-level experimentation and system optimization. By integrating components from multiple hardware providers, Horizon aims to refine its software stack across the full architecture, from control systems to higher-level programming tools. The in-house machine will function as a development and validation platform as the firm works with developers and enterprise clients to build real-world applications across sectors such as pharmaceuticals and finance.
The announcement comes ahead of Horizon Quantum’s planned U.S. listing through a merger with special purpose acquisition company dMY Squared Technology Group, in a deal that values the company at approximately USD 503 million. The development also reinforces Singapore’s ambition to establish itself as a regional quantum hub. The government’s National Quantum Strategy, launched in May 2024, committed SGD 300 million (USD 236.5) over five years to strengthen quantum research and processor development, building on earlier investments that date back to the establishment of Singapore’s first quantum research center in 2007.
