Spec 013 - Eigenbasis carrier of timeless QD records: simulation preregistration

Tristen Pierson

Published Oct 2, 2026• 0 citations
Publisher

Abstract

Preregistration of a simulation study: does the timeless quantum-Darwinism record texture of a central-spin model depend on the energy eigenbasis at exactly fixed spectrum? The Hamiltonian is conjugated by environment-only on-site unitaries (spectrum preserved, eigenbasis rotated) and paired texture statistics are compared under frozen verdict criteria. Protocol and code hash-pinned at freeze before the campaign; this registration precedes all campaign computation.

Spec 014 - NV-D3 physical leg: preregistered experimental protocol (base spec)

Tristen Pierson

Preregistration of the base spec for a two-stage experimental test: whether records in an NV central-spin system are of broadcast (population-encoded) or transversal (phase-encoded) form, tested via fragment-resolved tomography of the evolved state and its time-averaged (diagonal) ensemble. Stage A (device characterization + frozen predictions/thresholds) precedes any Stage-B data. Base spec frozen 2026-10-02 (hash-pinned in the program repo); this registration precedes any Stage-A data request.

Preregistered studies of record formation: quantum toy models, causal sets, and near-threshold perception

Tristen Pierson

A collection of preregistered studies on how records form and persist: simulation studies of redundant information records in quantum toy models (central-spin and spin-chain systems) and of counting laws in causal sets, together with secondary-data reanalyses of human experiments on cooperation and on near-threshold visual perception. Each linked project carries its own preregistration; the registration of record for every study is the time-stamped, DOI-bearing registration linked from its project page. All study designs and analysis criteria were frozen before analysis.

What carries the quantum Darwinism record texture’s robustness to spin-flip coupling strength? Edge-level interventions on the flip couplings in a central-spin model

Tristen Pierson

Preregistered simulation study. An earlier study in this series found the redundant record plateau in a central-spin model robust to rescaling the spin-flip coupling amplitudes, but that sweep preserved the coupling graph. This study discriminates three candidate carriers of the robustness — the specific coupling pattern, the coupling graph’s connectivity alone, or generic mixing strength — by interventions that delete, reduce, permute, or remove flip couplings at matched total strength.
