Gaussian quantum information over general quantum kinematical systems I: Gaussian states
Cedric Beny, Jason Crann, Hun Hee Lee +2
We develop a theory of Gaussian states over general quantum kinematical systems with finitely many degrees of freedom. The underlying phase space is described by a locally compact…

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…
