Beyond approximately twenty qubits, preparing ground states with adiabatic evolution outperforms conventional methods on Quantinuum’s hardware despite utilising potentially deeper circuits. This reversal occurs because higher precision approaches propagate errors faster as system size increases, while coarser resolution techniques maintain signal integrity. Trading accuracy for resilience represents a new direction in optimising near-term quantum computation.
