US EditionHorizon Quantum Becomes First Quantum Software Company to Own and Operate a Quantum Computer
Horizon Quantum integrates multi-supplier components in Singapore’s first commercial quantum computer to boost industry applications before its Nasdaq listing, valued at $503 million.
- On December 3, 2025, Horizon Quantum said it became the first private company to run a commercial quantum computer in Singapore, making it the first pure-play quantum software firm to own and operate one.
- Horizon built the testbed to gain full control of hardware and software, with Fitzsimons saying it enables a tightly integrated, hardware-agnostic execution stack to accelerate practical quantum applications.
- Built modularly, the system combines Maybell Quantum's cryogenic platform, Quantum Machines' control electronics, and Rigetti Computing's processor, allowing swaps to test diverse configurations and integrate with Triple Alpha.
- Horizon is preparing to list in the U.S. via a business combination with dMY Squared Technology Group, Inc., with regulatory filings and a definitive proxy to follow after the Registration Statement is effective.
- The launch aligns with Singapore's National Quantum Strategy, which pledged S$300 million over five years to boost local quantum development amid rising investment from Alphabet, Microsoft, and others.
