As demonstrated in a breakthrough experiment (Zhang et al., Nature 580, 345, 2020), microwave dressing of Rydberg states induces permanent rotating dipole moments leading to strong interactions between highly excited ions. Due to the separation of timescales, the fast electronic dynamics of Rydberg ions decouple from the slower motional modes of the linear Coulomb crystal, which typically mediate entangling gates in ground-state ion systems. Therefore, Rydberg ions enable significantly faster gate operations. In this talk, we will discuss how the unique features of trapped Rydberg ions can be used to realize fast and high-fidelity entangling gates, along with the associated challenges and strategies to address them. We will present different types of gate protocols for two- and multi-qubit entangling gates with trapped Rydberg ions, analyze sources of infidelity, and compare the performance with other platforms based on neutral atoms and ground-state ions. 001050047 536__ $$0G:(DE-HGF)POF4-5221$$a5221 - Advanced Solid-State Qubits and Qubit Systems (POF4-522)$$cPOF4-522$$fPOF IV$$x0 001050047 536__ $$0G:(EU-Grant)101046968$$aBRISQ - Brisk Rydberg Ions for Scalable Quantum Processors (101046968)$$c101046968$$fHORIZON-EIC-2021-PATHFINDEROPEN-01$$x1 001050047 909CO $$ooai:juser.fz-juelich.de:1050047$$popenaire$$pVDB$$pec_fundedresources 001050047 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)200181$$aForschungszentrum Jülich$$b0$$kFZJ 001050047 9131_ $$0G:(DE-HGF)POF4-522$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5221$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Computing$$x0 001050047 9141_ $$y2025 001050047 920__ $$lyes 001050047 9201_ $$0I:(DE-Juel1)PGI-2-20110106$$kPGI-2$$lTheoretische Nanoelektronik$$x0 001050047 980__ $$aconf 001050047 980__ $$aVDB 001050047 980__ $$aI:(DE-Juel1)PGI-2-20110106 001050047 980__ $$aUNRESTRICTED
