Design QC Unveils Fault-Tolerant Architecture License


“Despite significant advances in the development of quantum computers, the frequent computational errors in today’s hardware make them unsuitable for commercial use – and many manufacturers do not have a clear plan and dedicated resources to address this problem,” explains Professor Alexander von Humboldt Martin B. Plenio, co-founder of Design QC. “In the same way ARM’s RISC architecture revolutionized mobile computing by providing a more efficient and scalable platform, our fault-tolerant quantum architecture will take quantum computing to the next level. We are enabling hardware manufacturers to achieve fault-tolerant, next-generation quantum computing.”

From the NISQ system to quantum computing 2.0

The current quantum computing landscape is dominated by NISQ systems, characterized by a limited number of qubits, susceptibility to errors and noise, lack of fault tolerance, and scalability challenges. Even the most powerful quantum systems can only run hundreds of gates, far short of the millions needed to unlock the full potential of quantum computing. Only with the right error-correction architecture can imperfect hardware run the millions of gateways needed to revolutionize drug development, fertilizer manufacturing and carbon capture, and to drive scientific breakthroughs.

Experts agree that the realization of a fault-tolerant system capable of reliably handling high-end breakthrough applications requires millions of physical qubits, enabling the creation of sufficiently logical qubits through error detection and correction mechanisms. However, most of today’s successful manufacturers of quantum computers lack scalable architectures to create fault-tolerant systems. Developing this architecture not only requires a team with unique expertise in hardware engineering and fault tolerance, but also requires sophisticated software tools that can take years to build and months to implement effectively.

Enabling the entire industry, with the first architecture already developed

QC Design has developed proprietary architectures for photonics and spin qubits, the two leading platforms for building quantum computers.

“This architecture enables reliable quantum computing on quantum chips despite inevitable hardware imperfections such as loss, crosstalk, and fabrication errors. More generally, licensing for our architecture gives hardware manufacturers the fastest path to fault tolerance and allows them to do more with the same hardware,” explains Dr. Ish Dhand, CEO and co-founder of Design QC. “This saves hardware development effort for our customers, helps them avoid missteps, and allows them to beat incumbents.”

Building a fault-tolerant architecture requires a team with a unique combination of skills. At QC Design, the team comprises some of the world’s top experts in various fields, including fault tolerance theory, engineering, and hardware. With a wealth of experience spanning over 100 years in quantum technology, gained from leading universities and start-ups, the QC Design team is well-equipped to tackle the challenges of developing fault-tolerant quantum systems.

“Fault tolerance is critical for the next generation of quantum computers.” said dr. Lise Rechsteiner, General Partner at Vsquared Ventures, principal investor in QC Design. “As the driving force behind fault-tolerant architectures in quantum computing, Design QC has the potential to propel entire industries forward to the next generation, and emerge as a resounding success story.”

Several leading quantum computing start-ups have expressed interest in licensing architectures for next-generation quantum computers from QC Design to further develop their own hardware. QC Design not only launches its licensing offering but also releases brochurepowerful fault-tolerant design tools, as open source software, thereby making it widely available to the quantum computing community.

About QC Design: Founded in 2021, Design QC was co-founded by Ish Dhand, an experienced quantum computing researcher and former architecture team leader at Xanadu, together with Martin B. Plenio, Professor Alexander von Humboldt and Director of the Institute of Theoretical Physics at the University of Ulm with over 30 years in quantum technology. With a dedicated team of over 10 top experts, QC Design drives advances in fault-tolerant architectures and state-of-the-art simulation and design tools. Powered by Germany’s VC Vsquared Ventures deep technology, VC Quantonic-focused quantum technologies, and Salvia GmbH, the first-generation single-Family Office founded by Helmut Jeggle, and Germany’s Federal Ministry of Education and Research, QC Design is shaping the future of quantum computing.
