Noise in existing quantum processors only enables an approximation to ideal quantum computation. However, for the computation of expectation values, these approximations can be improved by error mitigation. This has been experimentally demonstrated in small systems but the scaling of these methods to lar...

The expectation value of an operator in quantum mechanics is the expected value of the operator, and can be considered to be a type of average value of the operator. It is not necessarily the most probable value. For example, in the case of a particle in a 1-D box. The ...
It seems fair to say that such an all-encompassing understanding of quantum mechanics does not exist yet. For instance, the categorical analysis in [1], [2] describes some of the basic underlying structure in terms of monoidal categories, daggers, and compact closure. However, an integrated ...

We studied the challenges students face with time dependence in quantum mechanics, specifically in the context of Larmor precession of spin. This research informed the creation and evaluation of a learning tutorial aimed at helping students grasp these concepts using a two-state system. The tutorial...
