Massy, France, July 23, 2024 – Quantum computing company Quandela has partnered with quantum networking company Welinq to develop a custom quantum interconnect. The collaborators aim to establish interconnected and error-protected clusters of photonic quantum computers by combining Welinq’s full-stack quantum interconnect technology with Quandela’s photonic quantum computing processors. The result, according to the partners, will be a custom quantum offering supporting fault-tolerant computing and the expansion of a comprehensive quantum network connecting numerous chips.

For Quandera, the partnership lays the foundation for error-corrected photon quantum computing. To realize the expected benefits of quantum computing, quantum processing units (QPUs) need to run algorithms across vast numbers of qubits, making error correction a fundamental requirement, according to the company. Photon QPUs benefit from their inherent modularity. This modularity favors scalability, as additional qubits can be seamlessly integrated into the system. Scaling to a large number of qubits requires interconnecting multiple independent photon QPUs.
Full-stack quantum interconnects based on efficient quantum memories are essential to link multiple QPUs, regardless of the modality of their qubits. These interconnects allow quantum information to be transferred between different processors with high fidelity and low latency, thereby increasing overall computational power.
Welinq’s interconnect technology provides native compatibility with all existing QPU architectures, according to company CEO and co-founder Tom Dallas. Dallas said he expects the collaboration will provide Welinq with an opportunity to push the boundaries of interconnect technology while also demonstrating its effectiveness in providing scalability and error correction for quantum computing.
