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 CFTs coupled via a single low-dimension operator. The coupling between the two CFTs 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.
