In 2025, German startup SAXON Q demonstrated a 4-qubit quantum computer that worked at room temperature. Now, the company is moving much further. It has opened orders for 128-qubit and 512-qubit quantum computers designed to fit inside standard server racks. That matters because quantum machines have long depended on complex cooling systems. SAXON Q’s approach could make quantum computing easier to install, access and use in real-world computing environments.
