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…
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…
Universal upper bounds for Gaussian information capacity
Kabgyun Jeong, Hun Hee Lee, Youngrong Lim
The most natural way to describe an information-carrying system containing a specific noise is an additive white Gaussian-noise (AWGN) channel. In bosonic quantum systems (especial…
Activation of quantum capacity of Gaussian channels
Youngrong Lim, Soojoon Lee
Quantum channels can be activated by a kind of channels whose quantum capacity is zero. This activation effect might be useful to overcome noise of channels by attaching other chan…
Correspondence between maximally entangled states in discrete and Gaussian regimes
Youngrong Lim, Jaewan Kim, Soojoon Lee +1
We study a general corresponding principle between discrete-variable quantum states and continuous-variable (especially, restricted on Gaussian) states via quantum purification met…
