In a nutshell

Recent advances in the generation and manipulation of ultrafast electronic excitations have shown that real-time coherent control of such excitations is now possible. This project focuses on developing the last two technological components needed to realize the first complete flying electron qubit: the on-demand generation of single-electron excitations on the picosecond timescale and the single-shot detection of these flying electrons. The project relies on cutting-edge theoretical approaches, including quantum field theory, direct microscopic-level simulations, and advanced machine learning techniques. It aims to achieve the first demonstration of a flying electron qubit and, more broadly, to make significant progress in the uncharted territory of quantum nanoelectronics at terahertz frequencies. Flying qubits could represent a complete paradigm shift in quantum computing, as they address both the scalability issue (the same circuit is used for each on-demand qubit, rather than one circuit per qubit) and the connectivity challenge (by going beyond nearest-neighbor interactions).
