Contrasting Effects of Control on Fidelity and Fidelity Deviation in Controlled Teleportation
Jeonghyeon Shin, Minjin Choi
Teleportation performance is commonly characterized by the average teleportation fidelity, while its variation over input states provides additional information captured by the fid…
Locally Acting Grover Mixers for Constraint-Preserving QAOA
Minjin Choi, Dongkeun Lee, Junghee Ryu
The Grover mixer quantum alternating operator ansatz (GM-QAOA) employs the Grover mixer to confine the quantum evolution to the feasible subspace defined by the problem. Its mixing…
Reducing Circuit Resources in Grover's Algorithm via Constraint-Aware Initialization
Eunok Bae, Jeonghyeon Shin, Minjin Choi
Grover's search algorithm provides a quadratic speedup over classical brute-force search in terms of query complexity and is widely used as a versatile subroutine in numerous quant…
Two Variations of Quantum Phase Estimation for Reducing Circuit Error Rates: Application to the Harrow--Hassidim--Lloyd Algorithm
Yonghae Lee, Minjin Choi, Youngho Min +2
We introduce two variations of the quantum phase estimation algorithm: quantum shifted phase estimation and quantum punctured phase estimation. The shifted method employs a bit-str…
A variational quantum algorithm for tackling multi-dimensional Poisson equations with inhomogeneous boundary conditions
Minjin Choi, Hoon Ryu
We design a variational quantum algorithm to solve multi-dimensional Poisson equations with mixed boundary conditions that are typically required in various fields of computational…
Investigating controlled teleportation capability of quantum states with respect to -separability
Minjin Choi, Jeonghyeon Shin, Gunho Lee +1
Quantum teleportation is an essential application of quantum entanglement. The examination of teleportation fidelity in two-party standard teleportation schemes reveals a critical…
