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 Qs approach could make quantum computing easier to install, access and use in real-world computing environments.

Absolute zero inside is much cooler than Intel inside

IBM says the linked cryogenic modules can cool to below 15 millikelvin and support far more chip connections, advancing its plan to build a fault-tolerant quantum computer by 2029
