The purpose of this article is to review two complementary schemes for quantum computation with trapped ions. We initially discuss the first proposal of quantum computations with cold trapped ions (J. I. Cirac and P. Zoller ; Phys. Rev. Lett. 74 , 4091, 1995) which requires, prior to any computation, laser cooling to the motional ground state. This proposal is closely related to the physics of generating and manipulating N‐particles entangled states in both ion traps and high‐Q cavities (cavity quantum electrodynamics). The second scheme is that of quantum computations with hot trapped ions (J.F. Poyatos , J.I. Cirac and P. Zoller ; Phys. Rev. Lett. 81 , 1322, 1998) which works at finite temperature and resembles physical ideas found in atom interferometry.
