Quantum leakage detection using a model-independent dimension witness

Author(s): Armands Strikis, Animesh Datta, and George C. Knee
Users of quantum computers must be able to confirm they are functioning as intended, even when they are remotely accessed. In particular, if the Hilbert space dimension of the quantum computer components is not as advertised—for instance, if they suffer leakage—errors can ensue and protocols may be ...
