Project description
Quantum coherence to enhance free electron technology
A cornerstone of modern physics, quantum coherence encompasses a variety of critical phenomena, such as Rabi oscillations and quantum entanglement, which lack classical analogues. This makes expanding our understanding of quantum coherence crucial for future quantum technologies, as well as for our exploration of quantum mechanics. The ERC-funded FreeQCC project aims to utilise breakthroughs in free electron beam nanophysics and quantum nano-optics to study quantum coherence effects and atomic-scale dynamics. The project will develop state-of-the-art experiments using advanced optical microscopy and electron technologies, addressing previous challenges in this field of research. The insights will be groundbreaking for the study of quantum coherence and the development of quantum information technologies.
Objective
Quantum coherence, a cornerstone of modern physics, encompasses phenomena like quantum entanglement and Rabi oscillations, which lack classical analogs. FreeQCC seeks to expand the frontiers of quantum mechanics by leveraging advances in free electron beam nanophysics and quantum nano-optics. Key questions include whether a free electron can be entangled with an atom or photon, and if a solid qubit's quantum coherence can be imprinted onto a free electron beam.
By exploiting the quantum properties of free electron beams and their interactions with matter and radiation, FreeQCC aims to reveal atomic-scale dynamics and quantum coherence effects previously inaccessible. The project will develop cutting-edge experiments using advanced electron and optical microscopy technologies, enabling precise control and measurement of free electrons and photons' quantum states. This includes measuring at the nanoscale optical polarization of nanophotonic devices via free electrons linear and orbital angular momentum transfer and photon polarization, and characterizing nanometric artificial atoms with ultra-high spatial and spectral resolution. These efforts will demonstrate entanglement between free electrons and photons mediated by plasmons, and the measurement of Rabi oscillations in individual artificial atoms with free electron beams. FreeQCC addresses the challenge of balancing temporal, energetic, and spatial resolutions while maintaining the sensitivity and cryogenic conditions needed to preserve quantum coherence.
Ultimately, FreeQCC aims to provide new insights into quantum mechanics and open unprecedented opportunities for manipulating and measuring quantum coherence at the nanoscale, potentially pioneering a new field in free electron physics and introducing a groundbreaking tool for quantum information technologies.
