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…
Upper bounds on the quantum capacity for general attenuator and amplifier
Youngrong Lim, Soojoon Lee, Jaewan Kim +1
There have been several upper bounds on the quantum capacity of the single-mode Gaussian channels with thermal noise, such as thermal attenuator and amplifier. We consider a class…
Quantum algorithm based on the -random linear disequations for the continuous hidden shift problem
Eunok Bae, Soojoon Lee
There have been several research works on the hidden shift problem, quantum algorithms for the problem, and their applications. However, all the results have focused on discrete gr…
Activation and superactivation of single-mode Gaussian quantum channels
Youngrong Lim, Ryuji Takagi, Gerardo Adesso +1
Activation of quantum capacity is a surprising phenomenon according to which the quantum capacity of a certain channel may increase by combining it with another channel with zero q…
