We present some generalizations of quantum information inequalities involving tracial positive linear maps between 6230&_mathId=si1.gif&_user=111111111&_pii=S0022247X16306230&_rdoc=1&_issn=0022247X&md5=f9007b104c3add9b55801c7ca7f6e76d" title="Click to view the MathML source">C⁎-algebras. Among several results, we establish a noncommutative Heisenberg uncertainty relation.
