Abstract

Traversable wormhole teleportation in the Sachdev-Ye-Kitaev (SYK) model links quantum channel integrity directly to black hole interior dynamics: The teleportation fidelity is a boundary-accessible probe of the many-body scrambling that underlies the holographic wormhole. We subject the SYK boundary to a gravitational-wave (GW)-inspired periodic Floquet deformation, constructed from the lowest-dimension bilinear sector of the SYK4 interaction and motivated by the Jackiw-Teitelboim-gravity holographic dictionary, and characterize the channel response via exact numerical time evolution with disorder averaging at βJ=2. The drive produces a coherent, frequency-selective fidelity suppression, validated by reoptimization under drive to separate genuine effects from calibration mismatch with four main results: (1) two distinct amplitude regimes separated near ɛ∼J, a perturbative sensing regime and a nonperturbative strong-drive regime; (2) the channel acts as a natural low-pass filter, most sensitive at ω≲β−1 with monotone recovery above the thermal scale; (3) an inspiral chirp drive displaces the fidelity peak to later readout times (by Δtscr(fid)=+0.11J−1, a subgrid displacement), and an out-of-time-order correlator (OTOC) diagnostic under a monochromatic drive independently resolves a scrambling delay of the same sign (Δtscr(OTOC)=+0.20J−1 at ɛ=0.20J, +0.85J−1 at ɛ=0.50J), with the delay growing monotonically with drive amplitude; (4) the drive-induced fidelity suppression is nonzero and shows no systematic decrease across N∈{10,12,14,16} Majorana modes, and is resolved above the disorder noise at three of the four system sizes. These results establish that holographic teleportation channels degrade gracefully and can be diagnosed via GW-inspired metriclike boundary deformations, with direct implications for near-term quantum-processor implementations of traversable wormhole protocols.
