Comparing Quantum Annealing and BF-DCQO
The study compared a quantum-classical hybrid algorithm called Bias-Field Digitized Counterdiabatic Quantum Optimization (BF-DCQO) against D-Wave's quantum annealers for optimization problems. The results showed that D-Wave's annealers consistently found solutions of much higher quality than claimed by BF-DCQO, using significantly less computation time. This suggests the quantum component in the hybrid approach offers minimal benefit to solution accuracy.
