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. 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."This demonstration by SaxonQ marks a milestone towards bringing quantum computing out of specialized laboratories and into everyday industrial environments," said Itamar Sivan, CEO and co-founder of Quantum Machines. "We're proud that Quantum Machines' OPX+ is an enabling technology behind this achievement, showing that precise, reliable quantum control is key to unlocking real-world quantum computing applications."

The demonstrations at Hannover Messe 2025 showcase two real-time applications.

Image Recognition
A live demo of quantum-enhanced image classification identifies a smiley vs. non-smiley in real-time, using an NV-center processor and an interactive graphical interface.

Quantum Chemistry
A quantum chemical calculation of H₂ energy levels is performed using a single NV-center qubit, with real-time graphical output. These mark the first-ever real-time quantum chemical calculation and image recognition on a mobile quantum computer in a public space.

Quantum Machines' OPX+, a high-precision microwave electronics system, was instrumental to this demonstration, enabling precise and dynamic qubit control in complex, real-world environments. The system dramatically reduces overhead while ensuring stability, making it a key enabler of SaxonQ's room-temperature, energy-efficient quantum computer.

Mobile quantum computing: SaxonQ and Quantum Machines
SaxonQ's quantum computer is built on spin defects in diamond chips, allowing room-temperature operation—a key advantage over conventional quantum systems that require cryogenic cooling, vacuum chambers, and high-maintenance infrastructure. The compact system is powered by a standard wall outlet, making it viable for industrial and research applications alike.Quantum Machines' OPX+ control system plays a crucial role in optimizing qubit manipulation, bringing stability, efficiency, and scalability to SaxonQ's technology.

With this demonstration, SaxonQ and Quantum Machines pave the way for practical quantum computing in real-world environments—an important step toward quantum-enhanced applications in chemistry, AI, and beyond.
