qbraid_algorithms.evolution.HeisenbergXYZ

class qbraid_algorithms.evolution.HeisenbergXYZ(reg=3, j_x=1.0, j_y=1.0, j_z=1.0, *args, **kwargs)

Heisenberg XYZ Model: H = Jx[XX + Jy[YY + Jz[ZZ

Implements all three Pauli interactions between neighboring qubits. Highly non-commuting due to different Pauli matrices on same qubits.

__init__(reg=3, j_x=1.0, j_y=1.0, j_z=1.0, *args, **kwargs)

Initialize the gate library with necessary components.

Parameters:

  • gate_import – List of imported gate libraries

  • gate_ref – List of available gate names

  • gate_defs – Dictionary of gate definitions

  • program_append – Function to append code to the program

  • builder – Reference to the circuit builder

  • annotated – Whether to use annotated syntax
