Holography-Inspired Teleportation

• Holography-inspired teleportation is a quantum protocol mapping teleportation circuits to traversable wormhole dynamics in holographic dualities such as AdS/CFT.
• It employs double-trace deformations and operator size dynamics to align phases (size winding) and achieve high-fidelity information transfer.
• Experimental implementations using Rydberg atoms, trapped ions, and superconducting qubits provide practical insights into quantum gravity and entanglement recovery.

Holography-inspired teleportation refers to a class of quantum information protocols in which the physics and mathematical structure of quantum teleportation circuits are mapped onto, or inspired by, the dynamics of traversable wormholes in holographic dualities such as AdS/CFT. These protocols utilize entanglement, scrambling, and engineered interactions—typically double-trace couplings or measurement-induced operations—so that quantum information injected on one side of an entangled system emerges on the other, mirroring the notion of information passing through a wormhole in dual gravitational language. Central to this approach is the ER=EPR paradigm, which equates Einstein–Rosen bridges (wormholes) in spacetime with quantum entanglement, enabling a geometric interpretation of teleportation as dynamical passage through spacetime (Susskind et al., 2017, Brown et al., 2019, Ahn et al., 2020, Vikram et al., 21 Jan 2026, Schuster et al., 2021, Antonini et al., 2022, Lykken et al., 2024).

1. Foundational Structure: Wormhole Traversability and Teleportation Circuit

The basic holography-inspired teleportation protocol uses two identical quantum systems—frequently modeled by conformal field theories or chaotic spin systems—each described by Hamiltonians $H_L$ and $H_R$. These are prepared in the thermofield double (TFD) state: $$|TFD\rangle = \frac{1}{\sqrt{Z}}\sum_n e^{-\beta E_n/2}\,|E_n\rangle_L\otimes|E_n\rangle_R^*$$ which is maximally entangled and, in AdS/CFT, dual to an eternal two-sided AdS black hole with an Einstein–Rosen bridge (ERB) connecting the two exteriors. In this geometry, absent any inter-system coupling, the bridge is non-traversable, and any information injected on one boundary remains inaccessible from the opposite side (Susskind et al., 2017).

Traversability arises when a double-trace deformation or equivalent coupling is turned on: $$H_{\text{int}} = g\,\delta(t)\,O_L(0)\,O_R(0)\qquad \Rightarrow \qquad U_{\mathrm{int}} = \exp\big[i\,g\,O_L(0)O_R(0)\big]$$ This engineered interaction injects negative null energy in the bulk, violating the average null energy condition (ANEC) and rendering the wormhole traversable for a finite time window. From the quantum circuit perspective, the protocol involves: (1) message insertion and scrambling; (2) measurement or coupling/gate; (3) classical information transfer (if needed); and (4) decoding on the recipient's side—mapping directly onto bulk events: wavepacket insertion, horizon crossing, shock wave (via double-trace), and emergence (Susskind et al., 2017, Bhattacharyya et al., 2021).

2. Operator Spreading, Size Winding, and Teleportation by Size

At the microscopic level, the success of teleportation depends on the dynamics of operator spreading and the specific structure of the interaction coupling. Time-evolved operators expand in the Pauli basis: $O(t) = 2^{-n/2}\sum_{P\in \text{Paulis}} c_P(t) P$ with the operator size distribution $P(s)$: $P(s) = \sum_{|P|=s} |c_P(t)|^2,$ and a complex winding component $$q(s) = \sum_{|P|=s} [c_P(t)]^2 = r_s e^{i\theta(s)}$$ (Brown et al., 2019).

In strongly chaotic or holographic models (e.g., SYK), the coupling $V$ acts as a "size" measurement, aligning or correcting size winding phases such that, at the correct coupling $g$, the two sides of the system realign, enabling high-fidelity teleportation. Perfect fidelity is achieved when all $\theta(s)$ align (phase cancellation), a phenomenon termed "teleportation by size" or "size winding." For a single qubit, the output state is a depolarizing mixture matched to the input at $g=\pi$ (Brown et al., 2019, Schuster et al., 2021, Lykken et al., 2024).

In more generic settings, where perfect size winding is absent, a variant—peaked-size teleportation—emerges, relying on sharp peaking of $P(s)$ and phase interference, but not on gravitational dynamics per se (Schuster et al., 2021). At high temperature or late times, non-holographic systems achieve only limited (single-qubit) capacity.

3. Bulk-Shockwave Geometry and Capacity Limitations

The gravitational dual provides a precise bulk interpretation: the double-trace coupling creates a negative energy shock along the horizon, imparting a shift in Kruskal coordinates ($v\to v+\alpha$), effectively "opening" a causal window through which injected signals can traverse. The required backreaction and window width are set by the scrambling time $t_*\sim (\beta/2\pi)\ln N$ and the coupling strength $g$. The capacity per use is

$C \sim 1 \;\text{qubit}$

with $g n \lesssim 1$ for $n$ qubits. The earliest emergence time is set by

$t_R \sim t_* + \frac{\beta}{2\pi}\ln\frac{1}{g}$

where larger $g$ enables larger messages at the cost of more challenging interaction engineering (Susskind et al., 2017, Ahn et al., 2020, Lykken et al., 2024). Capacity in higher-dimensional analogs is further suppressed with spacetime dimension.

4. Protocol Variants: Measurement-Induced, Bidirectional, and Symmetry-Deformed Constructions

Holography-inspired teleportation admits substantial generalization:

• Measurement-induced teleportation: Local projective measurements (LPMs) on a boundary region $A$ can "cut" the bulk dual geometry, deleting part of the original entanglement wedge, and "teleport" quantum information formerly encoded in $A$ into its complement $A^c$. The bulk dual involves entanglement wedge reconstruction, quantum extremal surfaces, and end-of-the-world branes, especially in tensor-network and finite-$N$ settings (Antonini et al., 2022, Antonini et al., 2022).
• Bidirectional and SWAP-by-scrambling: By mixing Hayden–Preskill-type recovery and traversable wormhole circuits, it is possible to implement bidirectional SWAP gates between collective degrees of freedom using only global scrambling interactions and postselection—enabling exchange of arbitrary quantum states probabilistically (Vikram et al., 21 Jan 2026).
• Non-Hermitian and PT-symmetric deformations: Introducing balanced non-Hermitian gain/loss terms (PT symmetry) in boundary Hamiltonians causes exceptional-point transitions. The PT-broken phase amplifies and purifies teleported signals without altering the causal traversability window, effectively turning the wormhole into an entanglement distiller (Joshi et al., 25 Jan 2026).

5. Laboratory Implementations and Diagnostics

The essential ingredients for experimental realization are: (1) two many-body entangled registers; (2) programmable scrambling dynamics; (3) two-body (or many-body) couplings across subsystems; (4) local or collective measurements for decoding. Specific platforms include:

• Rydberg atom arrays: Coherent manipulation of effective spin Hamiltonians, with forward/backward time evolution via echo protocols and global unitary couplings (Brown et al., 2019).
• Trapped ions: Both digital and analog simulation of Ising- or SYK-like models, TFD-state preparation by variational or adiabatic methods, and measurement/readout with fluorescence detection (Brown et al., 2019, Bhattacharyya et al., 2021).
• Superconducting qubits and quantum photonics: Proof-of-principle, small-$N$ demonstration of traversable wormhole circuits with high-fidelity control (Lykken et al., 2024).
• Measurement-induced protocols: Implementation of LPMs with local product basis measurements, enforcing brane-like boundary conditions in random tensor networks or code-based analogs (Antonini et al., 2022, Antonini et al., 2022).

Key diagnostics include the two-point or out-of-time-ordered correlators (OTOC) quantifying operator spreading, teleportation fidelity (entanglement fidelity of the output), and the retrieval of "memory" imprints reflecting in-bulk scattering events (Susskind et al., 2017, Brown et al., 2019).

6. Extensions: Higher Dimensions, Cosmological Contexts, and Information Bounds

Holography-inspired teleportation protocols generalize to hyperbolic (Rindler-AdS) slicing and higher dimensions, using double-trace deformations to open wormholes between dual CFTs on hyperbolic space. The bounds on transmitted information are set by the (bulk) area of the wormhole throat, scaling with the Bekenstein–Hawking entropy and decreasing with higher dimension (Ahn et al., 2020).

In Schwarzschild–de Sitter backgrounds, analogous traversable channels can be established by harvesting cosmological Hawking radiation into black-hole reservoirs and using negative-energy shockwaves to activate transmission. The maximum transferable information is set by extremal throat area or the location of the quantum extremal surface/island region (Aguilar-Gutierrez et al., 2023).

7. Theoretical and Practical Impact

Holography-inspired teleportation presents a unifying framework at the interface of quantum information theory and quantum gravity, recasting teleportation as the passage of information through dynamically emergent spacetime geometries. It establishes precise correspondences between entangling gates, scrambling, measurement-induced transitions, and bulk geometric phenomena such as traversable wormholes, entanglement wedges, and quantum extremal surfaces. These protocols not only offer insights into black hole information recovery and the nature of entanglement in gravity, but also drive advances in experimental simulation and quantum technology by exploiting the deep structure of duality (Susskind et al., 2017, Brown et al., 2019, Lykken et al., 2024, Antonini et al., 2022, Antonini et al., 2022).

Emerging directions include the exploration of teleportation in symmetry-rich or non-Hermitian systems, the systematic study of multipartite/multichannel generalizations, and the probing of quantum information/geometry duality with ever-larger and more complex quantum simulators.
