Title: My Adventures in Quantumland
Abstract: This is an expository talk about the mathematical picture language of quantum channels. In 1970, I started off my adventure in the mathematical wonderland of completely positive linear maps. Now, I am  fully awakened to the new  era of  quantum computers, with all sorts of information processes in the setting of non-commutative analysis. As the time runs backwards in an alternating world through the looking glass, I have to come back to the same old scene to release myself from quantum entanglements. In particular, I shall give a MODERN report in FUTURE perspective, on my 1975 paper (Completely positive linear maps on complex matrices, Linear Algebra Appl. 10 (1975), pp. 285-290) which has been cited in about 2000 recent research articles.
