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…
