We determine the secrecy capacity of the compound channel with quantumwiretapper and channel state information at the transmitter. Moreover, wederive a lower bound on the secrecy capacity of this channel without channelstate information and determine the secrecy capacity of the compoundclassical-quantum wiretap channel with channel state information at thetransmitter. We use this result to derive a new proof for a lower bound on theentanglement generating capacity of compound quantum channel. We also derive anew proof for the entanglement generating capacity of compound quantum channelwith channel state information at the encoder.
