Spatial Search on Johnson Graphs by Discrete-Time Quantum Walk

Hajime Tanaka, Mohamed Sabri, Renato Portugal

The spatial search problem aims to find a marked vertex of a finite graph using a dynamic with two constraints: (1) The walker has no compass and (2) the walker can check whether a…

Spatial Search on Johnson Graphs by Continuous-Time Quantum Walk

Hajime Tanaka, Mohamed Sabri, Renato Portugal

Spatial search on graphs is one of the most important algorithmic applications of quantum walks. To show that a quantum-walk-based search is more efficient than a random-walk-based…
