About
Oxford Quantum Circuits (OQC) is an Oxford-based quantum computing company that develops superconducting quantum processors using a proprietary qubit architecture called Coaxmon, which stores quantum information in a 3D structure rather than a flat 2D chip, enabling better qubit isolation and higher fidelity. OQC provides cloud access to its quantum processors through its Toshiba-backed cloud service and through AWS Braket, making it accessible to enterprise and research customers globally without on-premises quantum hardware. The company was the first commercial quantum computer provider in the UK and has established a European quantum computing cloud to serve enterprise and government customers requiring data residency within the EU. OQC focuses on hardware improvements that demonstrate a clear path to fault-tolerant quantum computing rather than maximizing near-term qubit count. Founded in 2017 as a spinout from Oxford University, OQC has raised over $100M from investors including Toshiba and SoftBank, and positions itself as the European alternative to IBM and Google in the quantum computing cloud market.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
About
ChatGPT is OpenAI's flagship AI assistant, launched in November 2022 and credited with igniting mainstream consumer adoption of generative AI. It crossed 100 million users in two months — the fastest consumer product to do so in history — and reached 400 million weekly active users by February 2025. Available as a free web and mobile app with a ChatGPT Plus subscription ($20/month) unlocking GPT-4o, advanced voice mode, image generation, and longer context.
