The French start-up Pasqal, which works on the development of quantum computers with neutral atoms, announced on April 23 that it had entered into a partnership with Welinq, specializing in quantum networks. Welinq offers solutions for interconnecting quantum processors (QPU). The next generation of QPUs should be based on algorithms requiring a large number of qubits. Likewise, applying error correction is expected to require additional qubits.
Increase the number of qubits
With this partnership, Pasqal counts “overcoming qubit scaling hurdles for error-prone quantum computing”. The networking of several QPUs, proposed by Welinq, should make it possible to increase the number of qubits and thus the computing power, while avoiding switching to the design of a larger-scale quantum processor.

“This is a milestone to stimulate the global quantum community towards the realization of quantum computing in networked quantum computing architectures”reacted Tom Darras, co-founder and CEO of Welinq.
Two ambitious roadmaps
Welinq was created in January 2022 by Tom Darras, Julien Laurat, Eleni Diamanti and Jean-Lautier Gaud. She comes from Sorbonne-Université, CNRS and PSL-University. To interconnect quantum computers, it develops and markets quantum links based on quantum memories with neutral atoms, cooled by laser. By the end of the year, it wants to produce an industrial prototype of its quantum memory “with industry-leading efficiency, storage time and fidelity”.
Pasqal, for its part, has included in its roadmap the transition to 10,000 qubits by 2026, with a scalable qubit architecture. The start-up also indicated that it had identified hardware-accelerated algorithms in different fields, such as quantum materials, graph machine learning, or optimization and differential equations. These algorithms, which “entering the development phase”can be used from next year.
