  Thermodynamics of quantum systems and associated quantum technologies are
rapidly developing fields, which have already delivered several promising
results, as well as raised many intriguing questions. Many-body quantum
technologies present new opportunities stemming from many-body effects. At the
same time, they pose new challenges related to many-body physics. In this short
review we discuss some of the recent developments on technologies based on
many-body quantum systems. We mainly focus on many-body effects in quantum
thermal machines. We also briefly address the role played by many-body systems
in the development of quantum batteries and quantum probes.
