Struct roqoqo::operations::GivensRotation
source · [−]pub struct GivensRotation {
control: usize,
target: usize,
theta: CalculatorFloat,
phi: CalculatorFloat,
}
Expand description
The Givens rotation interaction gate in big endian notation: $e^{-\mathrm{i} \theta (X_c Y_t - Y_c X_t)}\cdot e^{-i \phi Z_t/2}$.
Where $X_c$ is the Pauli matrix $\sigma^x$ acting on the control qubit, $Y_t$ is the Pauli matrix $\sigma^y$ acting on the target qubit, and $Z_t$ is the Pauli matrix $\sigma^z$ acting on the target qubit.
The unitary matrix representation is: $$ U = \begin{pmatrix} 1 & 0 & 0 & 0 \\ 0 & \cos(\theta) \cdot e^{i \phi} & \sin(\theta) & 0 \\ 0 & -\sin(\theta) \cdot e^{i \phi} & \cos(\theta) & 0 \\ 0 & 0 & 0 & e^{i \phi} \end{pmatrix} $$
Fields
control: usize
The index of the most significant qubit in the unitary representation.
target: usize
The index of the least significant qubit in the unitary representation.
theta: CalculatorFloat
The rotation angle $\theta$.
phi: CalculatorFloat
The phase $\phi$ of the rotation.
