"WebOct 12, 2024 · The main advantage of the Jordan-Wigner representation is its simplicity. The Jordan-Wigner representation is straight forward to derive. Recall that a state 0 j 0 j implies that spin orbital j j is empty and 1 j 1 j implies that it is occupied. This means that qubits can naturally store the occupation of a given spin orbital.
