Xanadu Quantum Technologies and Tower Semiconductor have announced that they are reinforcing their strategic partnership to accelerate the development and manufacturability of photonic quantum computing hardware, a crucial step towards the achievement of large-scale, fault-tolerant quantum computing systems.
The enhanced partnership is based on years of collaborative work and successful joint tape-outs of Xanadu’s custom photonic designs on Tower’s silicon photonics fabrication platform. Through the collaborative engineering of a custom material stack and process flow on Tower’s high-volume silicon photonics platform, the two companies are establishing the underlying infrastructure for next-generation photonic quantum computers, which could revolutionize the way quantum computers are developed from concept to commercial quantum hardware.
Photonic Quantum Computing: A Scalable Path Forward
Photonic quantum computing, which uses particles of light (photons) instead of conventional superconducting loops, is rapidly being recognized as one of the most promising methods of quantum computing, especially due to the fact that it can function at room temperature. This is in contrast to qubit-based technologies that need to be cooled to extremely low temperatures in order to function, and photonic quantum computing also has inherent networking capabilities.
Xanadu has already demonstrated significant breakthroughs in this domain, including the world’s first modular, networked photonic quantum processor (Aurora) – a system that features arrays of interconnected photonic processors with modular scaling potential.
However, scaling from laboratory prototypes to commercial quantum machines requires strong manufacturing ecosystems, which is precisely the strength that Tower Semiconductor offers with its mature high-volume silicon photonics technology. In this manner, the customization of the fabrication stack and the validation of designs on production-worthy flows enable the collaboration to tackle two of the most pressing issues in quantum hardware: scalability and manufacturability.
What the Expanded Collaboration Delivers
According to the joint announcement:
Co-engineered Production Flow: Xanadu and Tower have jointly developed a manufacturing-aligned workflow that supports Xanadu’s photonic circuit stack while ensuring compatibility with large-scale production processes. This alignment is designed to sustain performance as systems increase in complexity.
Component Optimization: Current work focuses on ultra-low loss silicon nitride (SiN) waveguides and integrated photodiodes, critical components for reducing loss and noise in photonic circuits – essential for real-world quantum performance at scale.

Manufacturability at Scale: The custom stack and validated production flow are said to meet the manufacturability requirements needed for future large-scale quantum computing systems, bridging the gap between R&D prototypes and industrial-scale quantum hardware.
Christian Weedbrook, Founder and CEO of Xanadu, highlighted how combining architectural innovation with Tower’s manufacturing expertise can help “move hardware from concept to prototype to demonstrator systems within a scalable manufacturing environment.”
Why This Matters for Quantum Computing
The drive to commercialize quantum computing hinges not just on demonstrating that quantum processors work, but on proving they can be reliably manufactured at scale – an area where many quantum hardware companies struggle. The tech industry’s broader push toward quantum advantage – achieving performance that exceeds classical systems on practical problems — depends on both hardware fidelity and production scale. (See Quantum Computing for industry context.)
Photonic systems, as they rely on photons for computation and networking, are able to avoid some of the cooling and control complexities associated with other qubit technologies. However, photonic quantum hardware is still faced with challenges such as reducing optical loss, incorporating detectors and control systems, and achieving uniform production of photonic components in the millions.
The Xanadu-Tower collaboration addresses these challenges by incorporating quantum-specialized designs into a high-volume photonics fabrication environment, which could potentially speed up the timeline for the development of commercially available quantum computers.
Effects on Businesses in the Quantum Computing Industry
1. Lowering Barriers for Quantum Hardware Startups
One of the biggest bottlenecks for quantum startups – especially hardware makers – is access to manufacturing partners that can produce complex quantum components repeatedly and reliably. By co-engineering production stacks with Tower Semiconductor, Xanadu helps establish a model that other hardware innovators might emulate, potentially fostering an ecosystem of foundry-friendly quantum hardware vendors.
2. Building Quantum-Ready Supply Chains
The inclusion of photonic quantum hardware within the roadmap of a full-fledged semiconductor foundry is bound to improve the supply chain of quantum technology on a global scale. This can be utilized not only by Xanadu but also by other companies wanting to leverage high-volume photonics fabrication.
3. Catalyzing Quantum-Linked Industries
Apart from the major participants in the quantum computing sector, other areas such as data centers, telecommunication, materials science research, cryptography, and highly advanced artificial intelligence may also benefit from the presence of quantum computers that can be commercially accessed. The photonic quantum processor may in the future offer a new paradigm for the processing of optimization, simulation, and secure communication, which are difficult for classical computing.
Wider Industry Implications
The expanded partnership between Xanadu and Tower demonstrates a key industry trend: bridging quantum innovation and semiconductor commercial production. It mirrors similar moves across the tech landscape where hardware companies are aligning early with manufacturing partners to avoid the “lab-only” trap that plagued earlier quantum efforts.
With the transition of quantum computing from R&D to practical applications, collaborations such as this one will go a long way in not only proving the photonic approach but also in unlocking the potential of fault-tolerant quantum computing.
Conclusion
While it may still take years before fully fault-tolerant quantum computers solve real-world optimization, chemistry, or AI problems at scale, strengthening the manufacturing foundation is an essential step – whether through silicon photonics or other quantum modalities. The Xanadu-Tower collaboration not only accelerates photonic quantum hardware progress but also signals that the Quantum Computing industry is maturing toward commercially viable production lifecycles – boosting confidence among investors, developers, and enterprise adopters planning quantum-first strategies.
