About SAXON Q
SAXON Q, based in Leipzig, develops and manufactures quantum computers based on NV centers (nitrogen-vacancy centers) in synthetic diamond, operated at room temperature (293 K) – without cryogenics, dilution refrigerators or vacuum chambers. Manufacturing follows four process steps from established semiconductor fabrication: deterministic ion implantation of individual nitrogen atoms (with sulfur co-implantation) into the diamond chip with a placement accuracy of 3 nm (sub-5 nm), thermal annealing in a vacuum furnace to form stable NV centers, nano-wiring with transparent coplanar microwave waveguides and control gates via CMOS lithography, as well as optical and RF control of the spin states. The product portfolio comprises the SXQ 4 (4 qubits, delivered 2023–2025), the multicore systems SXQ128 (128 qubits) and SXQ512 (512 qubits), as well as the SXQ 10k roadmap with more than 10,000 qubits on a single chip. Systems are programmable via Qiskit, OpenQASM and a proprietary gate language. Customers and partners include DLR and Fraunhofer (IWU); SAXON Q is a certified Bechtle partner and holds more than 220 patents.

Materials & Processes
Synthetic diamond (NV-center chip)
Base material with billions of carbon atoms in which NV centers are formed as stable qubits at room temperature.
Nitrogen (single-atom implantation)
Nitrogen atoms implanted individually at lattice coordinates form the NV qubits together with an adjacent vacancy.
Sulfur (co-implantation)
Co-implantation for creating large qubit arrays with nanometer precision and high yield.
