The Grover operator G is composed of the n-fold Hadamard transformation and of the conditional phase change and a renewed H transformation. If I have a unitary matrix, eg. the one for the phase shift in the Grover operator, how can I convict ... WebThe conditional phase shift gate introduces a phase shift only if a predetermined condition is satisfied. In one qubit system, the conditional phase shift gate is an unitary transform of the form [8]; C1(φ) = 1 0 0 eiφ! or C0(φ) = eiφ 0 0 1! (1) The C1(φ) introduces a phase shift if the qubit is in state 1i and C0(φ) introduces a phase ...
