Interdisciplinary Carnot Laboratory of Burgundy (ICB)

Involving about 300 people, in the fields of physics, chemistry-physics as well as materials engineering associated with mechanical engineering, the ICB laboratory embodies at the best level the research ambitions of the CNRS in Burgundy Franche-Comté (BFC), of the University of Burgundy, of the University of Technology of Belfort Montbéliard and, through these universities, of the University Burgundy Franche-Comté (UBFC) federation. The main scientific orientations of the laboratory are carried out by 6 departments (quantum interactions and control; photonics; nanoscience; mechanical design, optimization and modelling; metallurgical processes and materials durability; interfaces) and 4 tec…

Robust digital optimal control on IBM quantum computers

2022

The ability of pulse-shaping devices to generate accurately quantum optimal control is a strong limitation to the development of quantum technologies. We propose and demonstrate a systematic procedure to design robust digital control processes adapted to such experimental constraints. We show to what extent this digital pulse can be obtained from its continuous-time counterpart. A remarkable efficiency can be achieved even for a limited number of pulse parameters. We experimentally implement the protocols on IBM quantum computers for a single qubit, obtaining an optimal robust transfer in a time T = 382 ns.
