The Quantum Optics Conference is the tenth in the series that have been organized every four years since 1985. It will be held in Toruń (Poland) at the Hotel Bulwar, 5-11 September 2021.

One of its central aims is to bring together researchers from various sub-fields of quantum optics to offer a broad overview of current developments in this exciting domain.

Main topics of Quantum Optics conference include:
● ultracold Fermi and Bose gases
● quantum simulators
● spinor and dipolar gases
● topological states of matter
● quantum nonlocality and Bell inequalities
● precision measurements
● foundations of quantum mechanics
● high precision spectroscopy
● atomic clocks
● quantum communication
● quantum computing
● quantum thermodynamics

In addition to invited talks we also plan some number of contributed talks and a poster session.
Quantum Optics X will also be a satellite meeting of the BEC 2021 conference that will take place in Sant Feliu, Spain, 11-17 September 2021.
