LOng Range ENtanglement between charged levitated particles
The quantum superposition principle and entanglement are fundamental microscopic features essential for advanced quantum technologies such as telecommunication and computing. Entangling macroscopic mechanical oscillators probes the boundary between quantum mechanics and classical physics. The entanglement generated by the long-range Coulomb interaction between large-mass systems is a pivotal step toward achieving gravitationally induced entanglement in future experiments. The experimental study of electromagnetic quantization and vacuum fluctuations, in the context of entanglement between macroscopic systems, is vital for testing core quantum principles like causality and complementarity at the macro scale. In this project, I address the problem of generation of quantum entanglement between two optically trapped large-mass (~10^8 amu) particles using Coulomb interaction. Generating entanglement between macroscopic systems is challenging, but I've broken it down into the following primary objectives: 1 – Optical trapping and precise control over the net charge of two closely located dielectric particles; 2 – Quantum ground state cooling of two sub-micron charged particles in separate optical traps; 3 – Protocol and verification of steady-state entanglement. Importantly LOREN offers a platform for exploring intersections between thermodynamics, information theory, and quantum physics, with potential applications in quantum technology, sensing, and metrology. This study aligns with the current research priorities of the EU society, emphasizing quantum metrology & sensing and fundamental quantum science.

Project objective
The quantum entanglement (QE) of macroscopic mechanical oscillators is a unique resource to examine fundamental principles of quantum mechanics at the interface with classical physics.The emerging field of quantum optomechanics is meant to be a benchmark to study quantum phenomena on a macroscale. This Project is aimed to generate and study QE between center-of-mass motion of 2 macroscopic mechanical oscillators –optically levitated particles – a cutting-edge experimental platform offering outstanding control over particles motion, potential landscape and reservoirs. Importantly both particles will be charged to generate long range QE via Coulomb interaction.This study of electromagnetically induced QE is essential to examine consistency of macroscopic systems to basic principles of quantum mechanics. Going in complete parallel to a linear theory of quantum gravity it facilitates our understanding of quantization and vacuum fluctuations of a gravitational field and paves the way for quantum gravitational table-top experiments. The physical system under investigation is a general testbed for experiments at the interface of thermodynamics, information theory & quantum physics, with applications in quantum information technologies, sensing & metrology. This study is timely and highly relevant to the current EU research trends, it goes in line with prioritised research directions of H2020-EU123 programme following 2 out of 5 selected areas: Quantum metrology & sensing and Fundamental quantum science.This Project will be implemented in the group of Prof Aspelmeyer who are leading experts in quantum optomechanics. My background in light-matter interaction and open quantum systems perfectly fits the host group expertise in quantum control and their state-of-the-art facilities. This Fellowship will greatly improve my leadership skills, strongly diversify my knowledge, establish new academic links and boost my track record that would have a significant impact on my career.
