Quantum approximate algorithm for NP optimization problems with constraints
Yue Ruan, Samuel Marsh, Xilin Xue +3
The Quantum Approximate Optimization Algorithm (QAOA) is an algorithmic framework for finding approximate solutions to combinatorial optimization problems, derived from an approxim…
A Quantum-based Database Query Scheme for Privacy Preservation in Cloud Environment
Wenjie Liu, Peipei Gao, Zhihao Liu +2
Cloud computing is a powerful and popular information technology paradigm that enables data service outsourcing and provides higher-level services with minimal management effort. H…
Spatial search for a general multi-vertex state on graph by continuous-time quantum walks
Xi Li, Hanwu Chen, Yue Ruan +3
In this work, we consider the spatial search for a general marked state on graphs by continuous time quantum walks. As a simplest case, we compute the amplitude expression of the s…
The optimal search on graph by continuous-time quantum walks
Xi Li, Hanwu Chen, Yue Ruan +3
Chakraborty and Leonardo have shown that a spatial search by quantum walk is optimal for almost all graphs. However, we observed that on some graphs, certain states cannot be searc…
