Scalar Rains invariants of degree k are k-copy observables for quantum-code projectors, yet the copy order required for local differential separation is poorly understood. We construct an explicit eight-dimensional family of rank-two four-qubit code project...
Garbati, SamueleWe prove a finite-depth access-threshold separation theorem for public quantum records. In a single four-branch many-body environment, one label is encoded in a positive-rate, positive-distance quantum code while a second label is redundantly broadcast in l...
Garbati, SamueleThis record contains the preprint, supplemental material, source files, figures, and numerical data archive for the manuscript “Finite-time branch-record accumulation in one-dimensional baths: independent baselines, amplification, and nonredundant records”....

Garbati, SamueleQuantum Darwinism and related objectivity frameworks study how information about a quantum system is redundantly recorded in its environment. This preprint studies a downstream selection problem: when several candidate records coexist, which one is public u...
Garbati, SamueleThis record contains the supporting data, figures, research logs, metadata, and manifest files for the working paper “Access-scale selection of public quantum records in critical and gapped environments”. The central dataset documents the semi-analytic crit...
Garbati, Samuele, Garbati, SimonaThis record contains the post-PRA rebuilt preprint and source package for the working paper “Access-scale selection of public quantum records in critical and gapped environments”. The manuscript introduces a context-indexed selector for finite public quantu...
