Horizon Quantum Computing
Singapore-based company building software-development tools to enable the next revolution in computing
About Horizon Quantum Computing
A software company specializing in quantum computing, developing tools to streamline the creation of quantum software. The company is building a suite of tools, including compilers and a runtime environment, that will allow developers to write programs for quantum computers using standard programming languages, abstracting away the complexities of the underlying quantum hardware. This approach is intended to make quantum computing more accessible to a broader range of developers beyond quantum physicists.

Horizon Quantum Computing is also taking steps to become a vertically integrated quantum computing company by developing its own quantum computing hardware. This will allow the company to co-develop hardware and software, leading to a more tightly integrated and optimized quantum computing system. The company is targeting a public listing through a merger with a special-purpose acquisition company (SPAC), dMY Squared Technology Group. This transaction is expected to provide the company with the capital to further its research and development efforts and commercialize its products.
