We report enhanced interlayer tunneling with reduced linewidth at zero interlayer bias in a twist -controlled double monolayer graphene heterostructure in the quantum Hall regime, when the top (vT) and bottom (vB) layer filling factors are near vT = +/- 1/2, +/- 3/2 and vB = +/- 1/2, +/- 3/2, and the total filling factor v = +/- 1 or +/- 3. The zero-bias interlayer conductance peaks are stable against variations of layer filling factor, and signal the emergence of interlayer phase coherence. Our results highlight twist control as a key attribute in revealing interlayer coherence using tunneling.
