transformation can still be applied. It is only necessary to label the sites in an arbitrary way by a single index. Quantum computing The Jordan–Wigner transformation can be inverted to map a fermionic Hamiltonian into a spin Hamiltonian. A series of spins is equivalent to a chain of qubits for quantum computing. Some molecular potentials can be efficiently simulated by a quantum computer using this transformation.
