Quandela, a European leader in photonic quantum computing, has partnered with Welinq, a pioneering quantum networking company, to create custom quantum interconnects for photonic quantum computers. This collaboration combines Quandela’s expertise in photonic quantum computing with Welinq’s full-stack quantum interconnect technology, enabling the development of clusters of interconnected and error-corrected photonic quantum computers.
According to Niccolo Somaschi, CEO and co-founder of Quandela, this partnership marks a significant milestone in scaling photonic quantum computing. Tom Darras, CEO and co-founder of Welinq, notes that their interconnect technology is compatible with all existing Quantum Processing Unit (QPU) architectures. The partnership aims to advance QPU scaling, enabling fault-tolerant computing and the expansion of comprehensive quantum networks beyond a single chip. Photonic QPUs, such as those developed by Quandela, offer significant advantages due to their inherent modularity, while Welinq’s state-of-the-art quantum memories ensure the integrity of quantum information during transmission.
Advancing Quantum Computing through Strategic Partnerships
The recent partnership between Quandela, a European leader in photonic quantum computing, and Welinq, a pioneering quantum networking company, marks a significant milestone in the quest to scale photonic quantum computing. This collaboration combines Quandela’s expertise in photonic quantum processors with Welinq’s cutting-edge full-stack quantum interconnect technology, aiming to provide custom quantum links for photonic quantum computers.
The partnership is crucial for advancing Quantum Processing Units (QPUs) scaling, which requires executing algorithms across vast numbers of qubits while maintaining error correction. By combining Quandela’s quantum processors with Welinq’s state-of-the-art quantum interconnects, the collaboration will support fault-tolerant computing and the expansion of comprehensive quantum networks beyond the capabilities of a single chip.
“This strategic partnership with Welinq marks a significant milestone in our quest to scale photonic quantum computing,” said Niccolo Somaschi, CEO and co-founder of Quandela. “By combining Quandela’s expertise in photonic quantum processors with Welinq’s cutting-edge quantum interconnect technology, we’re laying the groundwork for clusters of interconnected, error-corrected photonic quantum computers.”
The Importance of Photonic QPUs and Quantum Interconnects
Photonic QPUs, such as those developed by Quandela, offer significant advantages due to their inherent modularity. This modular design enables computing scalability, as additional qubits can be seamlessly integrated into the system. As the carriers of quantum information, photons provide high-speed data transmission with minimal interference, making photonic QPUs highly efficient and reliable for complex quantum computations.
Full-stack quantum interconnects based on efficient quantum memories are crucial for linking multiple QPUs regardless of the qubit modality. These interconnects enhance the overall computational power by allowing quantum information to be transferred between different processors with high fidelity and low latency. Welinq’s state-of-the-art quantum memories ensure that the integrity of quantum information is maintained during transmission, which is essential for the development of robust and scalable quantum networks.
Implementing a Multi-Pronged Approach
The partnership between Quandela and Welinq is part of a broader strategy to develop fully-fledged clusters of photonic quantum computers. This approach involves working together to develop both hardware and algorithmic advantages over alternative approaches.
This technological partnership is in line with the announcement of the AQADOC project, the world’s largest initiative dedicated to distributed quantum algorithms, led by Welinq and of which Quandela is a key member. The aim of this project is to explore energy-related use-cases and develop the next generation of distributed software capabilities capable of running on several QPUs interconnected by the hardware work to be carried out as part of this strategic partnership.
