Quantum circuit for three-qubit random states

Olivier Giraud, Marko Znidaric, Bertrand Georgeot

par Bertrand Georgeot - 30 mars 2009

We explicitly construct a quantum circuit which exactly generates random three-qubit states. The optimal circuit consists of three CNOT gates and fifteen single qubit elementary rotations, parametrized by fourteen independent angles. The explicit distribution of these angles is derived, showing that the joint distribution is a product of independent distributions of individual angles apart from four angles.
