sounds almost wrong. For years, the field has been associated with giant refrigeration systems, elaborate laboratories and temperatures hovering just above absolute zero. Now a Leipzig startup says customers can order diamond-based machines that run without that infrastructure. But the most important number on these computers may not be the number printed on the front of the machine.

SAXON Q is selling a very different kind of quantum computer

SAXON Q, a spin-off from Leipzig University founded in 2021, has opened orders for two new systems: the SXQ128 and SXQ512. The company describes them as the first diamond-based nitrogen-vacancy, or NV-center, quantum computers to move beyond 10 qubits commercially. Both are designed to work at ordinary room temperature without cryogenic cooling, vacuum equipment or a specialized laboratory. SAXON Q says the SXQ128 is available now, while deliveries of the larger SXQ512 are scheduled to begin in the second quarter of 2027.

That changes the physical picture of quantum computing. Instead of placing a processor inside a dilution refrigerator operating near absolute zero, the machine can be deployed in a normal environment. SAXON Q lists an operating range of roughly 18 to 27 degrees Celsius and says its systems can run from a standard 230-volt outlet. Its newer platform is designed for rack and edge deployment, bringing quantum hardware much closer to the physical infrastructure already used for conventional computing.
