qoqo.operations.ComplexPMInteraction
- class qoqo.operations.ComplexPMInteraction
The complex hopping gate.
\(e^{-\mathrm{i} \left[ Re(\theta) \cdot (X_c X_t + Y_c Y_t) - Im(\theta) \cdot (X_c Y_t - Y_c X_t) \right] }\)
Where \(X_c\) is the Pauli matrix \(\sigma^x\) acting on the control qubit and \(Y_t\) is the Pauli matrix \(\sigma^y\) acting on the target qubit.
- Parameters:
control (int) – The index of the most significant qubit in the unitary representation.
target (int) –
t_real (CalculatorFloat) – The real part of the strength of the rotation \(Re(\theta)\).
t_imag (CalculatorFloat) – The imaginary part of the strength of the rotation \(Im(\theta)\).
