Quantum Information & the Fabric of Spacetime

This handout by Matthew J. Hall, created with assistance from GPT-5 Thinking, explores how spacetime itself may emerge from patterns of quantum entanglement.
Written in a teen-friendly, step-by-step format, it connects superposition, entanglement entropy, and holography to geometry and time. Each section pairs equations with plain-English explanations and “why it matters” insights.
Topics include mutual information, tensor networks, the Ryu–Takayanagi relation, bit-thread models, and modular Hamiltonians—culminating in a Chronos tie-in that interprets time as regulated correlation flow.
Part of Hall’s educational series linking time, gravity, and information through the Chronos framework.
