Decoding Quantum Search Advantage: The Critical Role of State Properties in Random Walks
Si-Qi Zhou, Jin-Min Liang, Ziheng Ding +3
Quantum algorithms have demonstrated provable speedups over classical counterparts, yet establishing a comprehensive theoretical framework to understand the quantum advantage remai…
Static and dynamic coherence fraction in the Bernstein-Vazirani algorithm
Si-Qi Zhou, Jin-Min Liang, Jiayin Peng +3
Quantum entanglement and coherence are crucial resources in quantum information theory. In some scenarios, however, it is not necessary to directly estimate entanglement or coheren…
Coherence Fraction in Grover Search Algorithm
Si-Qi Zhou, Hai Jin, Jin-Min Liang +3
The question of which resources drive the advantages in quantum algorithms has long been a fundamental challenge. While entanglement and coherence are critical to many quantum algo…
Extreme Capacities in Generalized Direct Sum Channels
Zhen Wu, Si-Qi Zhou
Quantum channel capacities play a central role in quantum Shannon theory, a formalism built upon rigorous coding theorems for noisy channels. Evaluating exact capacity values for g…
