- Abstract: In this paper we describe one of the most promising platforms for the
construction of a universal quantum computer, which consists of a chain of $N$
ions trapped in a harmonic potential, whose internal states work out as qubits,
and are coupled to collective vibrational modes of the chain. From such
coupling, it is possible to build interactions between different ions of the
chain, that is, qubit-qubit interactions that, together with individual
operations on the ions, allow building a quantum computer as first proposed by
Cirac and Zoller in the 1990s [Phys. Rev. Lett. 74, 4091 (1995)]. Here we
discuss from the physics involved in trapping ions in electromagnetic
potentials to the Hamiltonian engineering needed to generate a universal set of
logic gates, fundamental for the execution of more complex quantum algorithms.
Finally, we present the current state of the art of quantum computing in
trapped ion systems, highlighting recent advances made by companies and
government projects that use such architecture, such as IonQ and AQTION.
