Welinq, Qphox & Sorbonne University Announce Project Meet-Q to Advance Quantum Networking

Delft, Netherlands and Paris, France

October 15, 2025

Quantum technology leaders Welinq and Qphox, together with Sorbonne University, have announced a new joint initiative – Meet-Q – focused on realizing optical quantum interconnects to enable hybrid scalable quantum networking. The collaboration, which is supported by Quantum Delta NL and BPI France, brings together complementary technologies: quantum frequency converters and quantum memories. Together these will form the foundation for optical links between quantum processors and a quantum memory, which will allow to overcome critical bottlenecks in quantum networks and quantum computing.

‍

As quantum computing systems advance, the need for interconnecting processors into large-scale quantum networks becomes increasingly important. Optical interconnects are expected to play a pivotal role in this process, facilitating the transfer of quantum information between processors, scaling quantum computer size and enabling communication across long distances. The success of such interconnections is vital for the development of hybrid quantum networks and the realization of quantum computing's potential in areas such as medicine, materials development, cryptography and artificial intelligence.

‍

The Meet-Q project aims to bridge the gap between quantum processors and optical quantum network technology, leveraging the strengths of QphoX’s advanced quantum transduction technology, and Welinq's proprietary, world-leading quantum memory buffer (QDrive), the commercial result of two decades of foundational research from Sorbonne Université and CNRS.. Optical interconnects will grant access for leading quantum processor modalities, such as superconducting circuits, to quantum storage and repeater technology, enabling quantum data centers for fast and reliable computations. This collaboration will be critical to establish key technology interfaces and expand access to quantum networks.

Simon Gröblacher, Co-founder and CEO of QphoX, said:
“The ability to connect a quantum processor to a quantum memory will be of critical importance to realize hybrid quantum networks – we are excited to be working on bringing these technologies together with our world-leading partners Welinq and Sorbonne University.”

‍

Tom Darras, Co-founder and CEO of Welinq, added:
“We are excited to deepen our collaboration with QphoX. By complementing Welinq’s full-stack networking solution, their technology will empower our datacenter customers to easily integrate superconducting quantum computers into heterogenous architectures.”
