Enhanced energy-constrained quantum communication over bosonic Gaussian channels
The amount of information that a quantum channel can transmit is fundamentally bounded by the amount of noise in the channel. Here, the authors consider the realistic case with loss and thermal noise errors and prove that correlated multi-mode thermal states can achieve higher rates than single-mode...
