Query: How to Make Traversable Wormholes: Eternal AdS$_4$ Wormholes from
  Coupled CFT's   We construct an eternal traversable wormhole connecting two asymptotically
$\text{AdS}_4$ regions. The wormhole is dual to the ground state of a system of
two identical holographic CFT's coupled via a single low-dimension operator.
The coupling between the two CFT's leads to negative null energy in the bulk,
which supports a static traversable wormhole. As the ground state of a simple
Hamiltonian, it may be possible to make these wormholes in the lab or on a
quantum computer.
