Horizon Quantum signed a non-binding letter of intent to acquire Singapore’s Entropica Labs for an anticipated consideration of $27 million USD in Horizon Quantum Class An ordinary shares, subject to the completion of due diligence, related audits, the signing of definitive agreements and satisfaction of other customary conditions. The acquisition targets Entropica Labs’ work on Loom, a fault-tolerant compiler designed to simplify error correction for quantum hardware companies.
Founded in 2018 by Dr. Tommaso Demarie and Dr. Ewan Munro, former researchers at the Centre for Quantum Technologies in Singapore, Entropica Labs focuses on treating fault tolerance as a systems-software challenge. The company aims to build the infrastructure that transforms quantum hardware into usable, fault-tolerant computers.
Horizon Quantum’s $27 Million Acquisition of Entropica Labs
The deal targets a specific capability: simplifying error correction for quantum computers through software infrastructure, a critical step toward practical quantum computation. Founded in 2018 by Dr. Tommaso Demarie and Dr. Ewan Munro, former researchers at the Centre for Quantum Technologies in Singapore, Entropica Labs is developing Loom, a fault-tolerant compiler that is designed to let quantum hardware companies run error-corrected programs on their systems without building the full stack themselves.
According to the company, its mission is to build the software infrastructure that turns quantum hardware into fault-tolerant computers that developers can use. The acquisition remains subject to completion of audits and definitive agreement signing, but signals a commitment to advancing fault-tolerant quantum computing.
