    "abstract": "The corrected capacity of a quantum channel is defined as the best one-shot\ncapacity that can be obtained by measuring the environment and using the result\nto correct the output of the channel. It is shown that (i) all qubit channels\nhave corrected capacity log 2, (ii) a product of N qubit channels has corrected\ncapacity N log 2, and (iii) all channels have corrected capacity at least log\n2. The question is posed of finding the channel with smallest corrected\ncapacity in any dimension d.",
