On the frustrated Ising ring, parity-encoded QAOA prepares the exact ground state with a system-size-independent number of layers when local fields are distinct, while parity quantum annealing only halves the exponential gap closing exponent under realistic ancilla constraints.
The alternating unitary operators are defined using the driving Hamiltonian and the target Hamiltonian, respectively

Parity Mapping for Quantum Optimization on Frustrated Ising Rings
On the frustrated Ising ring, parity-encoded QAOA prepares the exact ground state with a system-size-independent number of layers when local fields are distinct, while parity quantum annealing only halves the exponential gap closing exponent under realistic ancilla constraints.
