  A fundamental ingredient in wormhole physics is the presence of exotic
matter, which involves the violation of the null energy condition. In this
context, we investigate the possibility that wormholes could be supported by
quark matter at extreme densities. Theoretical and experimental investigations
of the structure of baryons show that strange quark matter, consisting of the
u, d and s quarks, is the most energetically favorable state of baryonic
matter. Moreover, at ultra-high densities, quark matter may exist in a variety
of superconducting states, namely, the Color-Flavor-Locked (CFL) phase.
Motivated by these theoretical models, we explore the conditions under which
wormhole geometries may be supported by the equations of state considered in
the theoretical investigations of quark-gluon interactions. For the description
of the normal quark matter we adopt the Massachusetts Institute of Technology
(MIT) bag model equation of state, while the color superconducting quark phases
are described by a first order approximation of the free energy. By assuming
specific forms for the bag and gap functions, several wormhole models are
obtained for both normal and superconducting quark matter. The effects of the
presence of an electrical charge are also taken into account.
