Quantum algorithm to distinguish Boolean functions of different weights
Samuel L. Braunstein, Byung-Soo Choi, Subhamoy Maitra +3
We exploit Grover operator of database search algorithm for weight decision algorithm. In this research, weight decision problem is to find an exact weight w from given two weights…

Generalized protocol for distribution and concentration of Quantum information
Partha Mukhopadhyay
Alice can distribute a quantum state to spatially separated parties(say Bobs) by telecloning. It is possible for Charlie to reconstruct the quantum state to him if he sha…
