Papers you can read, cite and question
609 papers from the QNFO program, filed on nine shelves by the reader each one is written for: energy per answer, error correction, physics, numbers and p-adics, logic and formalism, AI and knowledge, autonomous systems, assessments, and cross-cutting essays. Every page renders its mathematics and can be questioned in place. How a living paper works.

Passive Error Rejection via Cryo-Fluidic Topological Phases: A Feasibility Analysis of the Topological Matter Engine
Active quantum error correction imposes a large and growing overhead of physical qubits, control electronics, and entropy-exporting measurement cycles on every scalable quantum processor. This paper examines a proposed alternative: a "Topological Matter Engine" in which errors are rejected…
Computation as Hamiltonian Isomorphism: A Mode-Based Taxonomy of Physical Computing Substrates
Special-purpose accelerators, neuromorphic chips, and optical processors are today evaluated by qubit or transistor counts, yet the machines that deliver the largest effective speedups are those whose physical dynamics directly embodies the target problem. This paper addresses a specific gap: no…
Actual Demand of a Computational Substrate: A Reconciled Demand-Side and Allocation Framework for Physical Computing Platforms
Debates about novel computational substrates—reservoir systems, post-qubit quantum architectures, thermodynamically bounded devices—are usually conducted from the supply side: what can a given physical system compute? This paper asks the complementary question posed by the QNFO programme: what is…
The Switching Economics of Hamiltonian Re-Entry Computation: A Cost-Model Comparison with Stored-Program Architectures
Stored-program (von Neumann) architectures pay a per-operation switching cost for instruction fetch, decode, and memory traffic, while a proposed Hamiltonian-computation paradigm identifies computation with continuous dynamical trajectories that re-enter a designated operating region of phase space.…
Planar Bosonic Error Correction with Heavy Fluxonium: A Quantitative Reassessment of Hardware-Efficient GKP Stabilization
Bosonic quantum error correction (QEC) encodes one logical qubit into an oscillator mode, promising fault tolerance with far fewer physical components than qubit-based surface codes. Until recently, however, all superconducting demonstrations of bosonic QEC relied on centimeter-scale…
TETRIS-Q: Tiling-based Effective Transient-fault Reduction and Parallelism Optimizations for Quantum Circuit Mapping
Quantum circuit mapping on Noisy Intermediate-Scale Quantum (NISQ) devices must satisfy physical connectivity constraints while minimizing both SWAP overhead and exposure to transient faults like decoherence. Existing compilers typically optimize qubit routing and noise-aware placement…
Locale Framework Applied to Quantum Computing Innovations & Practical Applications
Quantum computing is often presented through a small set of recurring claims: continuous-variable systems are naturally advantaged, more modes means more power, quantum advantage has been demonstrated at device level, statistics could in principle be non-standard, complex amplitudes are essential,…
JPCUB Competitive Landscape v2.0: System-Level Joules-per-Solution Estimates for 17 Quantum Computing Platforms from Published Specifications
The JPCUB P0 protocol (https://papers.qnfo.org/papers/joules-per-solution-metric/) defines the joules-per-solution metric — total system energy per correct answer — as a universal, physics-grounded benchmark for computational platforms. The qwav.tech competitive landscape displays six platforms with…
Topological Signal Processing
The inherent limitations of conventional digital signal processing—specifically the latency and energy bottlenecks imposed by analog-to-digital conversion—represent a critical barrier for next-generation systems like 6G networks. This paper introduces a novel physical computing paradigm that…
Stabilization of Gottesman-Kitaev-Preskill States
Harmonic oscillators enable hardware-efficient quantum error correction through the redundancy of infinite-dimensional Hilbert spaces. Conventional stabilization relies on measurement-based feedback, which is limited by detection latency and recoil heating in trapped ion systems. We propose an…
Thermodynamic Scaling of 4-Kelvin Topological Processors
Standard superconducting quantum processors are currently constrained by the thermodynamic bottleneck of millikelvin dilution refrigeration, which precludes the integration of high-speed control logic and limits scalability. This reliance on the 20 mK regime creates a “mainframe constraint” where…
Glossary
Acoustic/Phononic Systems: Systems that manipulate material vibrations (phonons) to encode information in collective modes and perform computation via controlled phonon-phonon interactions. Acoustic Transducers: Devices that convert electrical signals into sound waves and vice versa, used in QRC to…
