Multimarked Spatial Search by Continuous-Time Quantum Walk
Pedro H. G. Lugão, Renato Portugal, Mohamed Sabri +1
The quantum-walk-based spatial search problem aims to find a marked vertex using a quantum walk on a graph with marked vertices. We describe a framework for determining the computa…
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…
Comments on "Best conventional solutions to the King's problem"
Gen Kimura, Hajime Tanaka, Masanao Ozawa
Conventional solutions to the (Mean) King's problem without using entanglement have been investigated by Aravind [P. K. Aravind, ``Best conventional solutions to the King's problem…
Solution to the Mean King's problem with mutually unbiased bases for arbitrary levels
Gen Kimura, Hajime Tanaka, Masanao Ozawa
The Mean King's problem with mutually unbiased bases is reconsidered for arbitrary d-level systems. Hayashi, Horibe and Hashimoto [Phys. Rev. A 71, 052331 (2005)] related the probl…
