FRXGate

class FRXGate(phi, label=None)

X-rotation between the spin-up and spin-down state at one tweezer site.

The generating Hamiltonian of the FermionRx gate is

\(H = \phi (f^\dagger_{x,\uparrow} f_{x,\downarrow} + f^\dagger_{x,\downarrow} f_{x,\uparrow})\)

where \(x\) is the index of the mode and \(\phi\) is the free gate parameter

Initialize a FermionRX gate

Parameters:

• phi (float) – angle of the rotation

• label – optional
