  Superinsulators are dual superconductors, dissipationless magnetic monopole
condensates with infinite resistance. The long-distance field theory of such
states of matter is QED with dynamical matter coupled via a compact BF
topological interaction. We will quantize the 2D model in the functional
Schr\"odinger picture and show how strong entanglement of charges leads to a
phase which is a single-color, asymptotically free version of QCD in which the
infinite resistance is caused by the linear confinement of charges. This phase
has been experimentally detected in TiN, NbTiN and InO thin films, including
signatures of asymptotically free behaviour and of the dual, electric Meissner
effect. This makes superinsulators a ``toy realization" of QCD with Cooper
pairs playing the role of quarks.
