Former IBM Executive Joerg Behrend Joins Q.ANT as VP Hardware

Insider Brief

• Q.ANT has appointed former IBM executive Joerg Behrend as Vice President Hardware to lead development of its next generations of photonic processors.
• Behrend will oversee work spanning chip technology, processor architecture and production readiness of Q.ANT’s Native Processing Units (NPUs).
• His appointment is the fifth leadership addition at Q.ANT within 12 months as the company expands its photonic computing operations across Stuttgart and Austin.

PRESS RELEASE — Q.ANT, a leading provider of photonic processors for energy-efficient high-performance computing and artificial intelligence, is strengthening its leadership team with the addition of Joerg Behrend, who joined the company as Vice President Hardware. In this role, he will be responsible for advancing the next generations of Q.ANT’s photonic processors – from the underlying chip technology and processor architecture through to production readiness of the Native Processing Units (NPUs). Behrend reports to CTO Bruno Spruth and works across Q.ANT’s Stuttgart and Austin, Texas, sites. 

Behrend’s technical background spans processor development, high-performance computing, and parallel and distributed systems. Joerg Behrend brings more than two decades of experience in developing processor and system technologies. Most recently, he served as Senior Software Engineering Manager at IBM, where he led development teams at the intersection of hardware and software.  His technical background spans processor development, high-performance computing, and parallel and distributed systems. At IBM, he most recently served as Senior Manager for IBM Quantum at IBM Research & Development in Böblingen, where he was responsible for several R&D departments with up to 30 employees, focusing on cloud backend development, compilers, tooling, and runtime engineering for quantum computing — a role at the intersection of quantum hardware and software. 

“Photonic processors are running in data centers today. The harder part starts now: building them reproducibly, at volume, and across multiple generations,” says Dr. Michael Förtsch, Founder and CEO of Q.ANT. “Throughout his career, Joerg Behrend has seen what that takes: engineering hardware and software together until the result is a system a data center can rely on. That discipline is what separates a working prototype from a product.” 

“For two decades, I have worked on systems that all ran into the same ceiling in the end: energy per operation,” says Joerg Behrend. “Photonics moves that ceiling rather than managing it. What drew me to Q.ANT is how rare the assignment is – shaping an entirely new class of processor across multiple generations, from architecture through to operation in the data center.” 

“The U.S. market determines how quickly a new computing architecture gains traction,” says Bruno Spruth, CTO of Q.ANT and head of the Austin office. “Q.ANT is developing an entirely new class of processors. This requires leaders who can guide complex, cross-location teams through uncharted technical territory, especially as we expand to keep pace with the dynamic growth in the U.S. With Joerg  Behrend, we’ve been able to bring on board the perfect candidate for us.” 

Behrend is the fifth leadership position Q.ANT has filled within twelve months. In early 2026, Utz Bacher (previously IBM) joined as Vice President Software and Lars Bach as Vice President Operations. In April, Michael Krueger (previously Intel) joined as Vice President Commercials and Bruno Spruth (previously IBM) as Chief Technology Officer, who also leads the U.S. headquarters in Austin, Texas. The leadership team now combines experience from IBM, Intel and semiconductor manufacturing as the company moves from technology developer to product supplier: Q.ANT’s photonic systems are in use at, among others, the Leibniz Supercomputing Centre, the Jülich Supercomputing Centre (Forschungszentrum Jülich), and IONOS.
