  The Maldacena-Qi model describes two copies of the Sachdev-Ye-Kitaev model
coupled with an additional coupling, and is dual to the Jackiw-Teitelboim
gravity which exhibits an eternal traversable wormhole in the low-temperature
limit. In this work, we study an experimental consequence of the existence of
the traversable wormhole by considering the tunneling spectroscopy for the
Maldacena-Qi model. Comparing to the high-temperature black hole phase where
the bulk geometry is disconnected, we find that both the tunneling probability
and the differential conductance in the low-temperature wormhole phase show
non-trivial oscillation, which directly provides an unambiguous signature of
the underlying $\operatorname{SL}(2)$ symmetry of the bulk geometry. We also
perform bulk calculations in both high and low-temperature phases, which match
the results from the boundary quantum theory.
