Toward Prediction of Financial Crashes with a D-Wave Quantum Annealer
Entropy, 2023 The prediction of financial crashes in a complex financial network is known to be an NP-hard problem, which means that no known algorithm can efficiently find optimal solutions. We experimentally explore a novel approach to this problem by using a D-Wave
