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…
Genuine multipartite entanglement measures based on multi-party teleportation capability
Minjin Choi, Eunok Bae, Soojoon Lee
Quantifying entanglement is vital to understand entanglement as a resource in quantum information processing, and many entanglement measures have been suggested for this purpose. W…
Quantum advantage through the magic pentagram problem
Haesol Han, Jeonghyeon Shin, Minjin Choi +2
Through the two specific problems, the 2D hidden linear function problem and the 1D magic square problem, Bravyi et al. have recently shown that there exists a separation between $…
Quantum cryptographic resource distillation and entanglement
Minjin Choi, Soojoon Lee
We look into multipartite quantum states on which quantum cryptographic protocols including quantum key distribution and quantum secret sharing can be perfectly performed, and defi…
Genuine Secret-Sharing States
Minjin Choi, Soojoon Lee
Quantum secret sharing allows each player to have classical information for secret sharing in quantum mechanical ways. In this work, we construct a class of quantum states on which…
Quantum secret sharing and Mermin operator
Minjin Choi, Yonghae Lee, Soojoon Lee
Quantum secret sharing is well known as a method for players to share a classical secret for secret sharing in quantum mechanical ways. Most of the results associated with quantum…
