Quantum secure learning with classical samples
Wooyeong Song, Youngrong Lim, Hyukjoon Kwon +5
Studies addressing the question "Can a learner complete the learning securely?" have recently been spurred from the standpoints of fundamental theory and potential applications. In…
Quantum solvability of noisy linear problems by divide-and-conquer strategy
Wooyeong Song, Youngrong Lim, Kabgyun Jeong +5
Noisy linear problems have been studied in various science and engineering disciplines. A class of "hard" noisy linear problems can be formulated as follows: Given a matrix $\hat{A…
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…
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…
