Single photons from single ions: quantum interference and distant ion interaction Dissertation
... In analogy to the classical computer, the quantum computer uses gates to process quantum information. There is a finite set of quantum gates that are called universal, such that an arbitrary quantum computation on any number of qubits can be generated [4]. Single qubit gates (e.g. NOT gate, Hadamard ...
