He is Professor of Experimental Physics and Semiconductor Physics at Leipzig University, where he also serves as Dean of the Faculty of Physics and Earth System Sciences. With nearly 700 peer-reviewed publications and 40 years of experience in semiconductor physics, Grundmann has led SaxonQ’s development of a patented sulfur co-implantation process that raised NV-center qubit fabrication yield from roughly 10% to 85%, enabling the company’s SXQ128 and SXQ512 systems — the first diamond-based NV-center processors to exceed ten physical qubits. ### Host ![Katia Moskvitch](https://www.quantum-machines.co/wp-content/uploads/2026/06/Katia-Moskvitch.webp)#### Katia Moskvitch Communications director ![Logo](https://www.quantum-machines.co/wp-content/uploads/2026/05/QM_Logo_200x50_Black-1.svg) Katia Moskvitch is the Director of Communications at Quantum Machines, where she leads the company’s global communications strategy, brand narrative, and external relations across media, analysts, partners, and the broader quantum technology ecosystem.

Her journalistic work has spanned quantum computing, physics, space science, AI, cybersecurity, and emerging technologies, and her reporting has been featured in leading publications worldwide. Katia is also the author of *Neutron Stars: The Quest to Understand the Zombies of the Cosmos*, a nonfiction book blending science, history, and human relationships. ### Description As NV-center diamond qubits move from single-qubit lab demonstrations to multi-core, commercially available systems, precise and scalable control becomes the critical bottleneck. In this talk, Prof. Dr. Marius Grundmann, co-founder and CEO of SaxonQ, will present SaxonQ’s roadmap for diamond-based, room-temperature quantum computing — from the company’s patented sulfur co-implantation process, which lifted qubit fabrication yield from roughly 10% to 85%, to the recently launched SXQ128 and SXQ512 systems, the first NV-center processors to exceed ten physical qubits, with 8 and 16 entangled qubits per core respectively. Unlike superconducting or trapped-ion platforms, these systems run at room temperature, without dilution refrigerators or vacuum chambers, opening the door to mobile and edge deployment alongside data-center use. Grundmann will discuss how Quantum Machines’ control systems — first validated in a 2025 live demonstration of quantum chemistry and image-recognition on a mobile NV-center computer — deliver the high-fidelity, real-time control needed to coordinate multiple cores at once, and what it will take to scale diamond quantum computers toward SaxonQ’s roadmap of 10,000+ qubit systems. ![](https://www.quantum-machines.co/wp-content/themes/baseline/dist/images/seminar-form/bg-section.webp)## Register Now Live Seminar | 23 September 2026 | 07:00 PM GMT+3 ## More to explore [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/07/seminar-InnerHero-1024x265.webp) ### Quantum Error Correction/Detection and Dynamical Decoupling: Better Together or Apart? ![Prof. Daniel Lidar](https://www.quantum-machines.co/wp-content/uploads/2026/07/Group-427320788-150x150.webp) Prof. Daniel Lidar Watch now ](https://www.quantum-machines.co/seminars/quantum-error-correction-detection-and-dynamical-decoupling-better-together-or-apart/) [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/06/QM_0626_1680x434_Dr.-Ilai-Schwartz_seminar-InnerHero-1024x265.webp) ### First Individual Addressing of Organic Molecular Spin-Qubits for Versatile Spin-Photon Interfaces in Quantum Technologies ![Dr. Ilai Schwartz](https://www.quantum-machines.co/wp-content/uploads/2026/06/Dr.-Ilai-Schwartz-1-150x150.webp) Dr. Ilai Schwartz Watch now ](https://www.quantum-machines.co/seminars/first-individual-addressing-of-organic-molecular-spin-qubits-for-versatile-spin-photon-interfaces-in-quantum-technologies/) [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/05/QM_0526_1680x434_Dr.-Madelyn-Cain_seminar-InnerHero-1024x265.webp) ### Shor’s Algorithm is Possible with as Few as 10,000 Reconfigurable Atomic Qubits ![Dr. Madelyn Cain](https://www.quantum-machines.co/wp-content/uploads/2026/06/Dr.-Madelyn-Cain-1-150x150.webp) Dr. Madelyn Cain Watch now ](https://www.quantum-machines.co/seminars/shors-algorithm-is-possible-with-as-few-as-10000-reconfigurable-atomic-qubits/)
