Quantum Blockchain Technologies Plc (QBT.L) is a technology research and development company focused on advancing Bitcoin mining through disruptive blockchain innovations, leveraging artificial intelligence, quantum computing, cryptography, and novel FPGA and ASIC design techniques. The company develops proprietary Bitcoin mining technologies, including Method A, a SaaS client-server application that optimizes hashing computations by deciding between traditional brute force or confined searches based on AI-driven parameters to reduce energy use and improve winning hash detection; Method B, which guides searches within the SHA-256 space by selecting promising header parameters via firmware upgrades to enhance efficiency; and Method C, an AI Oracle that predicts in real-time whether specific headers will yield winning hashes, requiring integration into ASIC chips for hardware implementation, alongside proprietary mining hardware, software, mining pool services, and data services offered to select partners.
Founded in 2000 and headquartered at First Floor, 1 Chancery Lane, London WC2A 1LF, United Kingdom, the company operates primarily in the blockchain and cryptocurrency sectors, targeting Bitcoin miners, ASIC manufacturers, mining pools, and large-scale mining operations, with a growing emphasis on North American partnerships. In early 2025, Quantum Blockchain Technologies raised £2 million through a share placement to fund R&D expansion, hardware acquisitions, and commercialization efforts. Throughout 2025, it advanced live mining tests for its AI methodologies, filed patent applications including for an AI Oracle and enhancements like ASICBoost and ASIC EnhancedBoost, and engaged in strategic discussions under non-disclosure agreements with major ASIC manufacturers and miners following demonstrations at industry events such as Mining Disrupt 2025 in Florida, Bitcoin 2025 in Las Vegas, and Bitcoin Amsterdam 2024.
