Can a fast electron probe the quantum coherence of an artificial atom? Quantum coherence is central to quantum physics and underpins quantum information processing. Measuring it in individual systems such as quantum dots with nanometer spatial resolution would open new possibilities for exploring light–matter interactions and developing approaches to quantum-state readout. We now seek to cross a new frontier in quantum science and technology: accessing the quantum coherence of an individual artificial atom with a relativistic electron. The central question is whether, and how, this coherence can be encoded in the electron’s state and experimentally read out. This M2 internship, with the prospect of continuing into a PhD, will contribute to this effort within the ERC Advanced Grant FreeQCC. The project combines a state-of-the-art monochromated transmission electron microscope, a laser system, and engineered samples designed to enhance electron–light–matter interactions. During the internship, the student will help develop the optical setup, participate in experiments, and analyze the resulting data. We seek a curious and motivated student interested in quantum physics, nano-optics, and experimental research. The project offers the opportunity to explore an emerging research frontier with implications for both fundamental physics and future quantum technologies, through a combination of advanced instrumentation, experiments, and theory.
