Abstract
The rank-k numerical range has a close connection
to the construction of quantum error correction code for a noisy
quantum channel. For a noisy quantum channel, a quantum error
correcting code of dimension k exists, if and only if the associated
joint rank-k numerical range is non-empty. In this paper, the no-
tion of joint rank-k numerical range is generalized, and some state-
ments of [2011, Generalized numerical ranges and quantum error
correction, J. Operator Theory, 66: 2, 335-351.] are extended.
