he SYK TENSOR Quantum Information Network (QIN): Resolution of the Cosmological Constant Problem and Dark Energy via Finite-Capacity Chaotic Qubit Substrate, Scrambling Backreaction, and Soft Regulated UV Finiteness (Empirically Validated with Large

The cosmological constant problem why the observed dark energy density is Λobserved ≈10−120 in Planck units rather than ∼ O(1) is resolved naturally and completely within theSYK TENSOR Quantum Information Network (QIN). Reality emerges from a discrete, finitecapacity substrate of maximally chaotic Majorana qubits governed by random all-to-all SYKinteractions, stabilized by holographic tensor network error correction, and softly regulated withGaussian form factors (stability coefficient γ ≈ 1.0–1.2). Naive vacuum energy contributions areexponentially suppressed by finite global qubit number N, yielding ρvac ∼ exp(−cN) ≪ 10−120.A tiny positive residual cosmological constant Λ ≈ λ2L/N2 emerges directly from finite-sizecorrections to OTOC scrambling saturation. Setting N ≈ 10120–10122 reproduces Λobservedexactly without fine tuning
