Unconditional quantum advantage from a two-round CHSH problem in one dimension
Yonghae Lee, Jeonghyeon Shin, Soojoon Lee
We introduce a relation problem constructed from the Clauser--Horne--Shimony--Holt (CHSH) game, which we call the two-round one-dimensional CHSH problem. Its two-round structure en…
Improved bounds on quantum uncommon information
Yonghae Lee, Joonwoo Bae, Hayata Yamasaki +1
In classical information theory, channel capacity quantifies the maximum number of messages that can be reliably transmitted using shared information. An equivalent concept, termed…
The necessary and sufficient conditions when global and local fidelities are equal
Seong-Kun Kim, Yonghae Lee
In the field of quantum information theory, the concept of quantum fidelity is employed to quantify the similarity between two quantum states. It has been observed that the fidelit…
Quantum state rotation: Circularly transferring quantum states of multiple users
Yonghae Lee, Hayata Yamasaki, Soojoon Lee
Quantum state exchange is a quantum communication task for two users in which the users faithfully exchange their respective parts of an initial state under the asymptotic scenario…
One-shot quantum state exchange
Yonghae Lee, Hayata Yamasaki, Gerardo Adesso +1
The quantum state exchange is a quantum communication task in which two users exchange their respective quantum information in the asymptotic setting. In this work, we consider a o…
State exchange with quantum side information
Yonghae Lee, Ryuji Takagi, Hayata Yamasaki +2
We consider a quantum communication task between two users Alice and Bob, in which Alice and Bob exchange their respective quantum information by means of local operations and clas…
Hybrid quantum linear equation algorithm and its experimental test on IBM Quantum Experience
Yonghae Lee, Jaewoo Joo, Soojoon Lee
We propose a hybrid quantum algorithm based on the Harrow-Hassidim-Lloyd (HHL) algorithm for solving a system of linear equations. In our hybrid scheme, a classical information fee…
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…
State transfer with quantum side information
Yonghae Lee, Soojoon Lee
We first consider quantum communication protocols between a sender Alice and a receiver Bob, which transfer Alice's quantum information to Bob by means of non-local resources, such…
