Quantum Search with Prior Knowledge
Xiaoyu He, Jialin Zhang, Xiaoming Sun
Search-base algorithms have widespread applications in different scenarios. Grover's quantum search algorithms and its generalization, amplitude amplification, provide a quadratic…
Discouraging Pool Block Withholding Attacks in Bitcoins
Zhihuai Chen, Bo Li, Xiaohan Shan +2
The arisen of Bitcoin has led to much enthusiasm for blockchain research and block mining, and the extensive existence of mining pools helps its participants (i.e., miners) gain re…
Optimization from Structured Samples for Coverage Functions
Wei Chen, Xiaoming Sun, Jialin Zhang +1
We revisit the optimization from samples (OPS) model, which studies the problem of optimizing objective functions directly from the sample data. Previous results showed that we can…
Quantum Algorithm for Online Convex Optimization
Jianhao He, Feidiao Yang, Jialin Zhang +1
We explore whether quantum advantages can be found for the zeroth-order online convex optimization problem, which is also known as bandit convex optimization with multi-point feedb…
General Quantum Bernoulli Factory: Framework Analysis and Experiments
Yong Liu, Jiaqing Jiang, Pingyu Zhu +13
The unremitting pursuit for quantum advantages gives rise to the discovery of a quantum-enhanced randomness processing named quantum Bernoulli factory (QBF). This quantum enhanced…
