On a way to quantum entanglement via Coulomb interaction between optically trapped macroscopic particles — •Anton Zasedatelev1, Ayub Khodaee1, Klemens Winkler1, and Markus Aspelmeyer1,2 — 1University of Vienna — 2The Institute for Quantum Optics and Quantum Information
The quantum superposition principle and entanglement are one of the most striking features of the microscopic world and the key resource behind emerging quantum technologies, including quantum telecommunication, computing, metrology etc. The quantum entanglement of macroscopic mechanical oscillators is a unique resource to examine fundamental principles of quantum mechanics at the interface with classical physics. Electromagnetically induced quantum entanglement of macroscopic objects is essential for understanding the role of electromagnetic radiation quantization and vacuum fluctuations in ensuring consistency of the macroscopic systems to the basic principles of quantum mechanics, e.g. causality and complementarity. Here we discuss experimental challenges towards generation of quantum entanglement between center-of-mass motions of two highly charged sub-micrometer dielectric particles optically levitated in an ultra-high vacuum. This work is in progress, and takes the following steps: (i) optical trapping of two closely located and highly charged particles (ii) ground state cooling of their mechanical normal modes, (iii) generation and measurement of entanglement through long-range Coulomb interaction.
