... hold almost every ion, only a few ions are suitable for quantum computation. The following requirements should be met: • The electronic level structure should be simple to allow the realization of a closed two level system without the need of too many lasers. • The levels used for the qubit transiti ...

Quantum mechanics tells us, however, that we must think of a quantum system of n qubits as having a distinct probability of “being in” (that is, “being found in upon measurement”) each of the 2n classical states at a ...

By regarding perfect state discrimination as (k − 1)-state conclusive exclusion, we rederive this result. As an ap ...
