Quark flavour physics is an essential part of particle physics, which has produced ground-breaking results throughout its history. Precision measurements of decays of heavy hadrons provide stringent tests of the theory of particle physics. These tests are sensitive to scales of the interacting particles that lie beyond the reach of direct searches. Measurements with data of the LHC so far have provided a breadth of results, which advanced the field of flavour physics significantly. The talk will cover the current highlights of quark flavour physics, focusing on measurements of the LHCb experiment, ranging from strange to top quarks. Several unexpected results have emerged and will be discussed in detail. This is complemented by a range of measurements demonstrating the variety of activities in flavour physics based on experiments worldwide. Finally, an outlook onto the medium and long-term future of LHCb is given.
