About neQxt
neQxt is a spin-off of the Schmidt-Kaler research group at the University of Mainz, which has been working in quantum science for over 30 years and has been operating ion-trap quantum computers since 2010. The company develops and produces complete quantum computer systems through in-house manufacturing: from the quantum processing unit (QPU) with self-manufactured 3D ion traps to control electronics, photonics, vacuum systems and lasers, through to control and application software as well as Quantum Error Correction. The systems operate at room temperature without cryogenic systems and are characterized by high gate fidelities and low energy consumption. By the end of 2026, neQxt will operate 12 fully functional qubits with the goal of more than 1,000 qubits; the company was selected for the German quantum computing competition (640 million euros) and is supported by ongoing project funding of over 35 million euros. Customers are critical industries and institutions in Europe.
