Quantum key distribution between two groups using secret sharing
Sora Choi, Jinsoo Kim, Dong Pyo Chi
In this paper, we investigate properties of some multi-particle entangled states and, from the properties applying the secret sharing present a new type of quantum key distribution…
Function-dependent Phase Transform in Quantum Computing
Dong Pyo Chi, Jinsoo Kim, Soojoon Lee
We construct a quantum algorithm that performs function-dependent phase transform and requires no initialization of an ancillary register. The algorithm recovers the initial state…
Quantum Algorithm for Generalized Deutsch-Jozsa Problem
Dong Pyo Chi, Jinsoo Kim, Soojoon Lee
We generalize the Deutsch-Jozsa problem and present a quantum algorithm that can solve the generalized Deutsch-Jozsa problem by a single evaluation of a given function. We discuss…
The f-conditioned Phase Transform
Dong Pyo Chi, Jinsoo Kim, Soojoon Lee
We present a quantum algorithm for the f-conditioned phase transform which does not require any initialization of ancillary register. We also develop a quantum algorithm that can s…
Quantum Database Searching by a Single Query
Dong Pyo Chi, Jinsoo Kim
In this paper we give a quantum mechanical algorithm that can search a database by a single query, when the number of solutions is more than a quarter. It utilizes modified Grover…
A Polynomial-Time Quantum Algorithm for Collision Problem
Dong Pyo Chi, Jinsoo Kim
In this paper, we give a quantum algorithm which solves collision problem in an expected polynomial time. Especially, when the function is two-to-one, we present a quantum algorith…
