Center node: "entanglement assisted capacity of quantum channels with side information"
  Abstract: Entanglement-assisted communication over a random-parameter quantum channel with channel side information at the encoder is considered. This describes a scenario where the quantum channel depends on the quantum state of the input environment. While Bob, the decoder, has no access to this state, Alice, the transmitter, performs a projective measurement on her environment and encodes her message accordingly. A full characterization of the entanglement-assisted capacity is given.

  with members:
    - "channel simulation and coded source compression"
    - "causal state communication"
    - "a constrained channel coding approach to joint communication and channel estimation"
