New York and Paris, June 11, 2026 — Quantonation, the world’s leading venture firm for quantum and physics technologies, today announced the appointment of Magnus Bengtsson and Elizabeth Ruetsch as Venture Partners, strengthening the firm’s ability to support portfolio companies as they scale from scientific breakthroughs into global businesses.

The appointments form part of Quantonation’s broader effort to expand its operating platform and provide founders with access to experienced industry leaders across commercialization, manufacturing, strategic partnerships, and global market expansion. Earlier this year, Quantonation closed its oversubscribed €220 million second fund, making it the largest dedicated quantum investment firm globally by assets under management.

The global buildout of AI infrastructure is creating significant/unprecedented opportunities for quantum, photonics, advanced semiconductors, and other deep-tech companies. As demand accelerates and technologies move from laboratory breakthroughs to industrial development, founders increasingly face challenges that extend beyond technology development.

Scaling production, building commercial organizations, navigating global supply chains, securing strategic customers, forging industry partnerships, and expanding internationally require expertise that is often difficult for early-stage companies to access.

“Building transformative technology is only part of the journey,” said Christophe Jurczak, Managing Partner at Quantonation. “The next challenge is turning scientific leadership into industrial and commercial leadership. Magnus and Elizabeth bring decades of experience helping technology companies scale globally, and their expertise will be invaluable to founders across our portfolio.”

Bengtsson joins Quantonation with nearly three decades’ experience in the photonics and laser industries. Most recently, he was Chief Commercial Officer of Coherent Corp., a key supplier of optical networking, semiconductor and photonic technologies underpinning the global AI infrastructure buildout. He led a global sales and service organization of around 1,300 professionals generating $6 billion in annual revenue. Prior to that, he led Coherent’s industrial laser division, returning multiple business units to profitability while overseeing operations spanning the US and Europe.

“Many of Quantonation’s portfolio companies are developing technologies that have the potential to reshape entire industries,” said Bengtsson. “I’m excited to help founders navigate the challenges of commercialization, customer adoption, and organizational scaling so they can maximize that impact.”

Ruetsch joins Quantonation with over 30 years of experience in wireless communications, aerospace and defense, automotive, and semiconductor markets during her time at Hewlett Packard, Agilent Technologies and Keysight Technologies.

Most recently, she was the General Manager of Keysight’s Quantum Solutions Team. Keysight conducts business with over 40,000 customers worldwide including most Fortune 1000 companies across wireless communications, aerospace and defense, automotive, and semiconductor markets. Prior to that, she led global sales for Keysight’s EDA team with team members located in over 40 countries.

“One of the most exciting aspects of deep-tech investing today is seeing groundbreaking science move into real-world deployment,” said Ruetsch. “Quantonation has built the world’s leading portfolio in quantum and physics-based technologies, and I look forward to helping founders accelerate that transition from laboratory innovation to global impact.”

Bengtsson and Ruetsch will work closely with companies across Quantonation’s existing funds, providing strategic guidance, industry introductions, commercial mentorship, and operational support. They will also contribute to the firm’s growing network of global industry leaders supporting the next generation of quantum and deep-tech scale-ups.

Since its founding, Quantonation has backed pioneering companies across quantum computing, communications, and sensing, photonics, advanced materials, and enabling deep technologies. As the portfolio continues to mature, the firm is expanding its capabilities to help founders navigate the increasingly complex path from breakthrough science to global commercialization.
