qrisp.operators.fermionic.FermionicOperator.to_qubit_operator#

FermionicOperator.to_qubit_operator(mapping_type='jordan_wigner')[source]#

Transforms the FermionicOperator to a QubitOperator.

Parameters:

mappingstr, optional: The mapping to transform the Hamiltonian. Available is jordan_wigner. The default is jordan_wigner.

Returns:

Examples

We map a singular fermionic ladder operator to a QubitOperator to see the Jordan-Wigner embedding.

>>> from qrisp.operators import a
>>> O = a(4)
>>> print(O.to_qubit_operator())
