ROSIE System
With the historic US quantum order secured by RIBER, photonics on silicon is moving forward.
One of the world’s leading manufacturers of molecular beam epitaxy (MBE) equipment for the semiconductor industry, RIBER, recently announced a major new order for its state-of-the-art ROSIE system from a client in the US that specializes in quantum computing. This crucial advancement reinforces RIBER’s leadership in integrated silicon photonics, a crucial enabler for the next generation of computers, and represents a significant step in the commercialization of the company’s cutting-edge technology.
For 300mm silicon substrates, the ROSIE system an acronym for Riber Oxide Silicon Epitaxy is a completely automated platform. Its purpose is to develop thin layers of oxide materials, particularly barium titanate (BTO). In order to create integrated electro-optic modulators components that are vital to the development of silicon photonics BTO is a strategic material. This US procurement highlights photonics’ growing significance as a crucial technology for quantum computing and highlights the tremendous interest in silicon photonics.

Both the technological legitimacy of ROSIE system and the substantial faith in RIBER’s solutions are demonstrated by this new order from a leading US participant in quantum computing technology. With complete commercial industrialization expected in 2027, the system is expected to be delivered in 2026. RIBER is positioned to fulfill the new demands of the constantly changing semiconductor and quantum markets with this timeframe. A further indication of the increasing momentum in silicon photonics solutions is the order’s complete alignment with RIBER’s strategic strategy.
The three-year collaboration agreement with the Novo Nordisk Foundation Quantum Computing Programme (NQCP) in Denmark, which was announced on June 17, 2025, provides the foundation for the US order, which builds upon a significant previous engagement. Earlier, this collaboration was formed for the industrial qualification of ROSIE system, the first 300mm photonics-focused machine that works with silicon fabs. As part of this partnership, RIBER sold NQCP the first ROSIE unit, which is expected to be delivered in the second half of 2025. A photonics-focused pilot line will incorporate this system, and collaborative development efforts will concentrate on streamlining the procedure for a quick production ramp-up.

The Île-de-France Region and Bpifrance have supported the ROSIE system project since 2021 as part of the France 2030 investment plan, demonstrating how French technology is becoming a major enabler for next-generation quantum components. Among the strategic markets that ROSIE is aimed at are photonic quantum technologies, optical computing, and ultra-fast optical communications (Datacom/Telecom). With the construction of the Quantum Foundry Copenhagen, the Danish partner, NQCP, is a top-tier research project focused on creating fault-tolerant quantum computing (FTQC) hardware and quantum algorithms.
Following the initial collaboration with NQCP, this latest US order further demonstrates RIBER’s dedication to ground-breaking innovation by fusing its state-of-the-art MBE knowledge with industrial compatibility for silicon manufacturing lines. It emphasizes the value of industry-science cooperation in influencing the quantum and semiconductor landscapes of the future and shows how RIBER may deliver cutting-edge technology to a global scale.
Summary
The major order that RIBER, a prominent manufacturer of molecular beam epitaxy (MBE) equipment, received for its ROSIE platform from a US quantum computing company is explained in this essay. Designed to generate thin oxide layers, such as barium titanate, on 300 mm silicon wafers, the ROSIE system is essential for integrated electro-optic modulators in silicon photonics, a major quantum technology enabler. With delivery planned for 2026 and full industrialization in 2027, this new order strengthens RIBER’s position in the developing semiconductor and quantum sectors. The paper emphasizes the trustworthiness of RIBER’s solutions and the technological legitimacy of ROSIE system in the quickly developing field of quantum computing.
