• Authors: Jonas Hawellek, Athin Mohan, Hadi Aghaee, Christian Deppe,
• Abstract summary: It explores communication over a two-sender, two-receiver classical interference channel, enhanced by the availability of entanglement resources between transmitters. It addresses the persistent challenge of the lack of a general capacity formula, even in the purely classical case, and highlights the striking similarities in achievable rate expressions when assessing quantum advantages.

• Abstract: This paper explores communication over a two-sender, two-receiver classical interference channel, enhanced by the availability of entanglement resources between transmitters. The central contribution are an inner and outer bound on the capacity region for a general interference channel with entangled transmitters. It addresses the persistent challenge of the lack of a general capacity formula, even in the purely classical case, and highlights the striking similarities in achievable rate expressions when assessing quantum advantages. Through a concrete example, it is shown that entanglement can significantly boost performance in certain types of channels.

• Detecting positive quantum capacities of quantum channels [9.054540533394926]
  A noisy quantum channel can be used to reliably transmit quantum information at a non-zero rate. This is because it requires computation of the channel's coherent information for an unbounded number of copies of the channel. We show that a channel's ability to transmit information is intimately connected to the relative sizes of its input, output, and environment spaces.
