Providing links to the future

We provide solutions to interconnect quantum processors in order to drastically increase their computational power and to make them quantum-accessible at a distance.

Our quantum links enable

Scale-up of quantum computing

Interconnecting Quantum Computers refers to the ability to entangle physically-separated Quantum Processing Units (QPUs) to each other. We use photons synchronized by Quantum Memories to share Quantum Information and create entanglement between QPUs. Such Quantum Links allow to increase the number of qubits available for computation, thus overcoming the limitations of individually-taken intermediate-scale Quantum Processors.

Short-cut to Error Correction

Imperfections in quantum hardware lead to errors in computation. Errors are corrected by redundantly encoding quantum information on many physical qubits. Connecting our Quantum Memories to QPUs and interconnecting QPUs between each other will allow more diverse and enhanced error-correction strategies.

Deployment of QPUs

As of today, more of 75% of worldwide High-Performance Computing (HPC) centers plan to use quantum computing and deploy Quantum Processing Units in their premises. Networking quantum machines in these centers is a foremost importance for exploiting their computing capabilities at their maximum.

Quantum Information Networks

Quantum networks rely on the transfer of quantum information between quantum nodes at short and long distance to perform quantum-enhanced tasks such as distributed quantum computing or quantum cryptography. Efficient quantum memories are the key missing asset for enabling entanglement-based networked quantum computing and long-distance quantum communications.

Our quantum links are based on the world’s most efficient quantum memories

Our founding team is the unique team gathering all the scientific, technical, business and industrial skills to develop a reliable quantum link solution.

Tom Darras
CEO

After an engineering degree in Physics at ESPCI Paris, Tom received his PhD in quantum physics from Sorbonne Université where he worked on quantum teleportation protocols for quantum interconnects. After his PhD he transitioned from academia to entrepreneurship and co-founded Welinq in 2022. As a young physicist and entrepreneur, he always thrives by facing ambitious technological challenges to transform proof-of-concepts laboratory experiments into real-world solutions that will have a massive impact on science and industry. He has been awarded Grand-Prix of the French Innovation i-Lab contest in 2022 and winner of the Hello Tomorrow Global Challenge 2023.

Jean Lautier-Gaud
Head of Business Development and Sales

Jean Lautier-Gaud, PhD, MBA, conducted his research in Quantum Sensing in the field of high precision measurements with cold-atoms at LNE-SYRTE laboratory (Observatoire de Paris), the French National Metrological Institute for Time & Frequency. He worked on simplifying cold-atom experimental set-ups, in order to facilitate their use outside of laboratories. He developed a compact atom accelerometer dedicated to on-field measurements. His work contributed to the foundation of the French company Muquans, later acquired by Exail. After an MBA degree, he has been the Director of Business Development and Sales for Exail Quantum Sensors for 8 years.
