Gravitational Wave-Induced Scrambling Delay in SYK Wormhole Teleportation

TL;DR

This paper investigates how gravitational-wave-like perturbations affect the fidelity of traversable wormhole teleportation in the SYK model, revealing a delay in scrambling and channel robustness across system sizes.

Contribution

It introduces a GW-inspired Floquet deformation to the SYK model and demonstrates a genuine delay in quantum information scrambling, with detailed numerical analysis and implications for quantum technologies.

Findings

Fidelity suppression is frequency-selective and amplitude-dependent.

The SYK channel acts as a low-pass filter sensitive at low frequencies.

A chirp drive delays the scrambling peak, confirmed by OTOC measurements.

Abstract

Traversable wormhole teleportation in the Sachdev-Ye-Kitaev (SYK) model links quantum channel integrity to black hole interior dynamics, using teleportation fidelity to probe holographic scrambling. We subject the SYK boundary to a gravitational-wave (GW)-inspired periodic Floquet deformation, mimicking a leading-order metric-strain perturbation from the JT-gravity dictionary. We characterize the channel response via exact numerical time evolution with disorder averaging at $\beta J = 2$. The drive produces a coherent, frequency-selective fidelity suppression, yielding four main results: (i) two amplitude regimes separated near $\varepsilon \sim J$ (perturbative sensing vs.\ strong-drive); (ii) the channel acts as a low-pass filter, most sensitive at $\omega \lesssim \beta^{-1}$ with monotone recovery above the thermal scale; (iii) an inspiral chirp drive delays the fidelity peak by $\Delta t_{\rm scr}^{(\rm fid)} = +0.11\, J^{-1}$, corroborated by an out-of-time-order correlator (OTOC) diagnostic ($\Delta t_{\rm scr}^{(\rm OTOC)} = +0.20\, J^{-1}$), establishing a genuine scrambling delay; and (iv) the effects persist across $N \in \{10, 12, 14, 16\}$ Majorana modes, indicating no systematic finite-size suppression. These results establish that holographic teleportation channels degrade gracefully under GW-inspired boundary deformations, with direct implications for near-term quantum processor implementations of traversable wormholes.
