The Next-Codes project is based on the expertise of Gilles Zémor (Bordeaux Mathematical Institute, Bordeaux Institute of Mathematics, UMR CNRS, University of Bordeaux, Bordeaux INP) on the decoding of quantum codes and the design of new families of quantum Tanner codes (Leverrier and Zémor 2022b; 2022a; 2023). Quantum codes are one of the technological barriers to be overcome in order to ultimately achieve an “FTQC” (Fault-Tolerant Quantum Computer): a quantum computer capable of executing quantum algorithms without errors due to noise generated by the hardware or to interactions with the outside world. A long-term collaboration with Quandela has been launched since December 2023.
