Struct roqoqo::operations::Fsim
source · [−]pub struct Fsim {
control: usize,
target: usize,
t: CalculatorFloat,
u: CalculatorFloat,
delta: CalculatorFloat,
}
Expand description
The fermionic qubit simulation (Fsim) gate.
$$ U = \begin{pmatrix} \cos(\Delta) & 0 & 0 & i \sin(\Delta) \\ 0 & -i \sin(t) & \cos(t) & 0 \\ 0 & \cos(t) & -i \sin(t) & 0 \\ -\sin(\Delta) \cdot e^{-i U} & 0 & 0 & -\cos(\Delta) \cdot e^{-i U} \end{pmatrix} $$
Note
The qubits have to be adjacent, i.e., :math:|i-j|=1
has to hold. This is the only case
in which the gate is valid as a two-qubit gate (due to the Jordan-Wigner transformation).
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.
t: CalculatorFloat
The hopping strength.
u: CalculatorFloat
The interaction strength.
delta: CalculatorFloat
The Bogoliubov interaction strength $\Delta$.
