This data repository contains the information necessary to reproduce the main results of the paper “Quantum computational displacement sensing”. The repository contains both the data required to generate the figures of the main manuscript and the supplemental material, as well as source code for running the experiments and simulations presented in the paper. There are two main folders: code_simulation (which consists of the training code and the baseline simulations) and code_experiment (which covers the experimental code). The corresponding requirements for running them are in the zipped folder. The data folder contains all simulation and experimental raw and processed data generated. The figures folder contains all the plots presented in the manuscript.
A theoretical and computational framework separating accepted protocol support, record-quality diagnostics, replicated entropy moments and implementation-level bookkeeping. A bounded positive effect induces a completed quotient Hilbert space; integer density-matrix moments are calculated through permutations on identical product copies; signed entropy increments telescope along a fixed reduction. Version 3.2 clarifies support versus distinguishability, finite-dimensional assumptions, higher-order observables, finite-copy uncertainty, numerical rank, logarithm units, additive ledgers and the limits of return diagnostics. A failed chosen inverse does not alone establish irreversible dynamics, and zero entropy residual does not establish state or apparatus return. The companion provides new reproducible central-spin and 500-state SWAP checks, an explicitly defined dephasing control, the recovered historical ledger script and its rerun, editable equations and manuscript sources. Missing historical central-spin and entropy-fit generators are disclosed. The associated Finite Record Protocol Calculator v0.3.0 supplies instrument/record diagnostics, Python and JavaScript parity checks, strict validation and a reduced-state entropy-path interface. This is the first deposit of this manuscript series, superseding working drafts v1.0 through v3.1. All examples are analytic or simulated; no laboratory measurements, empirical anchor, independent Born-rule derivation, emergent geometry or thermodynamic cost inferred from the accepted effect alone are claimed. The manuscript uses CC BY 4.0. Executable software and source code in the companion retain separate rights; see LICENSE_SCOPE.txt and software_dependency/RIGHTS.txt.
This repository contains the computational data and source code required to reproduce the numerical validations and figures presented in the manuscript "Exact Microcanonical Density of States and Fibonacci Convolutions in the 1D Ising Model" and its accompanying Supplemental Material. The dataset includes the following files: Numerical Validation.nb: This Wolfram Mathematica notebook contains the complete numerical verification of the exact combinatorial degeneracy formulas derived in the study. It implements three independent computational approaches—brute-force enumeration via the full Ising Hamiltonian, analytical combinatorial formulas based on Fibonacci/Lucas convolutions, and the algebraic transfer-matrix formalism. The code validates the exact macroscopic degeneracies across the full excitation spectrum for both open-chain and closed-ring topologies. Thermodynamic Quantities.nb: This Wolfram Mathematica notebook contains the numerical routines used to compute and generate the plots of the thermodynamic quantities presented in the appendix of the main manuscript. Software Requirements: To execute and modify the provided .nb files, Wolfram Mathematica is required.
