World's first diamond-powered portable quantum computer, Germany sets world record

August 12, 2026

BERLIN, Germany--German startup Saxon Q has launched the world's first portable diamond-powered quantum computer operating at room temperature without requiring complex cryogenic cooling equipment, according to the WORLD RECORD ACADEMY; the; the system fits inside a standard server rack, connects directly to a conventional alternating-current power outlet, and supports configurations reaching 128 qubits.

"A German startup has debuted the world's first diamond-based quantum computing system to exceed 10 qubits.

"The machine, built by engineers at Saxon Q, is a nitrogen-vacancy (NV) quantum computer, meaning it uses defects in synthetic diamonds as quantum bits (qubits) to perform quantum operations. Qubits can be manipulated to represent the 0s and 1s of data, as well as quantum states that are superpositions of both the 0s and the 1s,"the Live Science says.

"The hardware is currently available in rack-mounted systems featuring up to 128 qubits, with 512-qubit configurations available for delivery next year. According to the company's road map, the goal is to scale to 10,000 qubits and beyond after 2030.

"The world's first portable, diamond-powered quantum computer capable of exceeding 10 qubits was officially launched in August 2026 by the German startup Saxon Q. This breakthrough machine, available in configurations up to 128 qubits (model SXQ128), bypasses the need for massive, extreme sub-zero cooling hardware.

"By leveraging the unique physics of synthetic diamonds, the hardware operates entirely at room temperature and can be deployed outside traditional laboratory environments. (AI Overview)

"Leipzig/Hanover: SaxonQ, developer of the first mobile quantum computer, and Quantum Machines, the leading provider of advanced hybrid quantum-classical control solutions, announced today a milestone demonstration of real-time quantum computing on SaxonQ’s mobile quantum computer at Hannover Messe 2025," Quantum Machines says.

"The live demonstrations included a quantum chemical calculation of H₂ energy levels and basic real-time image recognition, marking the first time anyone has shown such applications running on a portable room-temperature quantum computer publicly, demonstrate the potential of mobile quantum computing outside laboratory conditions.

“Developing a mobile quantum computer that runs in real-world environments—without cryogenic cooling and powered by a simple wall plug—is a challenge that requires the best available control technology. Quantum Machines provides exactly that. This successful demonstration proves that we can run reliable quantum operations on-site. It’s an exciting step toward bringing quantum computing to industrial applications,” says Dr. Frank Schlichting, CEO of SaxonQ.
