Struct roqoqo::operations::GivensRotation

pub struct GivensRotation {
    control: usize,
    target: usize,
    theta: CalculatorFloat,
    phi: CalculatorFloat,
}

Where X_c is the Pauli matrix σ^x acting on the control qubit, Y_t is the Pauli matrix σ^y acting on the target qubit, and Z_t is the Pauli matrix σ^z acting on the target qubit.

Fields

control: usize

The index of the most significant qubit in the unitary representation.

target: usize

theta: CalculatorFloat

The rotation angle θ.

phi: CalculatorFloat
