  We study the effects of conservation laws on wormholes that are made
traversable by a double trace deformation. After coupling the two asymptotic
boundaries of a maximally extended $(d+1)$ dimensional black brane geometry
with $U(1)$ conserved current operators, we find that the quantum matter
stress-energy tensor of the corresponding bulk gauge fields in the hydrodynamic
limit violates the averaged null energy condition (ANEC), rendering the
wormhole traversable. Applying our results to axionic two-sided black hole
solutions, we discuss how the wormhole opening depends on the charge diffusion
constant, how this affects the amount of information that can be sent through
the wormhole, and possible implications for many-body quantum teleportation
protocols involving conserved current operators.
