Query: Leggett-Garg inequality with a kicked quantum pump   A kicked quantum nondemolition measurement is introduced, where a qubit is
weakly measured by pumping current. Measurement statistics are derived for weak
measurements combined with single qubit unitary operations. These results are
applied to violate a generalization of Leggett and Garg's inequality. The
violation is related to the failure of the noninvasive detector assumption, and
may be interpreted as either intrinsic detector backaction, or the qubit
entangling the microscopic detector excitations. The results are discussed in
terms of a quantum point contact kicked by a pulse generator, measuring a
double quantum dot.
