Query: Quantum tomography of noisy ion-based qudits   Quantum tomography makes it possible to obtain comprehensive information
about certain logical elements of a quantum computer. In this regard, it is a
promising tool for debugging quantum computers. The practical application of
tomography, however, is still limited by systematic measurement errors. Their
main source are errors in the quantum state preparation and measurement
procedures. In this work, we investigate the possibility of suppressing these
errors in the case of ion-based qudits. First, we will show that one can
construct a quantum measurement protocol that contains no more than a single
quantum operation in each measurement circuit. Such a protocol is more robust
to errors than the measurements in mutually unbiased bases, where the number of
operations increases in proportion to the square of the qudit dimension. After
that, we will demonstrate the possibility of determining and accounting for the
state initialization and readout errors. Together, the measures described can
significantly improve the accuracy of quantum tomography of real ion-based
qudits.
