Papers you can read, cite and question
728 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.

CEI Invariance: Architectures as Equivalence Classes of Causal Density and Energy Fidelity
Computational architectures are today chosen for a substrate by benchmarking, an expensive process that must be repeated for every substrate-architecture pair and gives no guidance before hardware exists. No existing framework predicts, from thermodynamics alone, which architecture classes a…
Thermodynamic Feedback Limits on the Scalability of Surface‑Code Quantum Error Correction
Quantum error correction (QEC) is essential for fault‑tolerant quantum computation, yet the control electronics, wiring, and cryogenic heat load required for each correction cycle generate heat that raises the qubit temperature and thereby increases the intrinsic physical error rate. This creates a…
Thermodynamic Feasibility of Tubulin Conformational Switching as a Heat‑Free Parallel Computation Substrate
Cellular information processing is limited by the heat generated during molecular state changes, which constrains the scalability of intracellular computing architectures. The hypothesis that tubulin dimers in microtubules can act as binary switches with near‑Landauer‑limited energy consumption has…
Thermodynamic Scaling Limit of Active Quantum Error Correction
Active quantum error correction (QEC) underpins fault‑tolerant quantum computation, yet its control circuitry dissipates heat that must be removed by cryogenic infrastructure. A hard scalability limit arises when the localized power density generated by control pulses exceeds the Kapitza thermal…
THz-Driven Synthetic-Dimension Lattices in Thin-Film Lithium Niobate: Thermal-Photon Occupation Limits and the Operating-Point Criterion at 3.5 THz
Synthetic-dimension photonics uses the frequency modes of a single optical waveguide as the sites of an artificial lattice, promising high-dimensional photonic circuits without three-dimensional fabrication. Progress toward interaction-capable synthetic lattices in thin-film lithium niobate (TFLN)…
Thermodynamic Divergence of Active Quantum Error Correction Overhead: A Kapitza-Limited Feasibility Threshold for Gate-Based Architectures
Active quantum error correction (QEC) is conventionally analyzed as an algorithmic resource problem: how many physical qubits and gate cycles are needed per logical qubit. We propose a complementary thermodynamic feasibility criterion. In a gate-based architecture, every QEC cycle is driven by…
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? Far less attention is paid to the complementary question of what demand is…
Thermodynamic Budgeting for Hybrid Quantum-Classical Computing: A Three-Layer Energy Model with Explicit Arithmetic and a 15-Month Validation Roadmap
Hybrid quantum-classical (HQC) computing is the dominant near-term paradigm, yet its energy accounting is rarely made explicit: the classical control, readout, cryogenic, and orchestration hardware surrounding the quantum processing unit (QPU) can dominate the total power budget, eroding any…
Thermodynamic Trade-off Frontiers for Neuromorphic Processors: A Quantum-Inspired Non-Equilibrium Model of the Energy–Speed Boundary
Neuromorphic processors promise order-of-magnitude gains in energy efficiency, but no predictive framework currently connects device-level dissipation to system-level computational throughput. We develop a non-equilibrium thermodynamic model in which a neuromorphic processor is treated as a driven,…
Landauer-Limit Energy Floor and JPCUB Normalization for Cryogenic Quantum Control Electronics
Cryogenic quantum control electronics dissipate energy many orders of magnitude above the thermodynamic minimum implied by Landauer's principle, and the gap matters for the joules-per-compute economics of fault-tolerant machines. This paper computes the Landauer floor for a rotated surface-code…
A Lower Bound on Energy Cost per Logical-Qubit Operation in Surface-Code Quantum Error Correction
Surface-code quantum error correction translates one logical qubit into a two-dimensional array of physical qubits, and the energy cost of that translation is rarely quantified at the level of a logical operation. This paper specifies a minimal, convention-explicit energy model for a rotated…
Error Correction Is a Landauer Machine: The Thermodynamic Floor of Quantum Error-Correction Overhead
Quantum error correction is priced almost exclusively in combinatorial currency: rate, distance, threshold. The physical bill — the energy paid for performing the correction itself — goes unpriced by the field's headline metrics. This paper prices it. Every cycle of active (measurement-based) error…
The Physics of Computation: Fundamental Limits and the Honest Boundaries of Post-Classical Computing
Phase III of the Qubit Delusion series. Examines fundamental physical limits on computation: Landauer bound, Margolus-Levitin theorem, Bremermann limit, Bekenstein bound. Shows that quantum error-correction overhead (1e2-1e3 physical operations per logical operation) multiplies thermodynamic cost…
Alpha Pi Project
The Alpha Pi project begins with a practical engineering challenge: quantum states are exquisitely fragile, decohering rapidly due to environmental noise. This fragility stems not merely from technical limitations but from a deeper mathematical vulnerability: the continuous real‑number field that…
Quantum Abacus
The scalability of active, gate-based quantum computers is fundamentally challenged by the “Thermodynamic Wall,” where the heat from control electronics becomes prohibitive. This study computationally investigates the “Quantum Abacus,” a passive quantum computing architecture that circumvents this…
Adaptive Thick Skin
Standard approaches to robustness in open systems rely on static topological protection, maintaining a constant energy bias to enforce non-reciprocity. However, this strategy incurs a prohibitive thermodynamic cost, or “quiet tax,” during benign environmental conditions. Here, the “Adaptive Thick…
Thermodynamic and Informational Bottlenecks of Scalable Fault-Tolerant Quantum Computation
The promise of fault-tolerant quantum computation rests on its ability to solve certain intractable problems exponentially faster than classical computers. However, this theoretical promise is challenged by a cascade of interconnected physical bottlenecks, where the act of scaling quantum resources…
Thermodynamic and Quantum Constraints on Scalable Quantum Computing
The central tension in scalable quantum computing lies between the exponential growth of quantum information density and the polynomial limits of cryogenic heat extraction. This thermodynamic bottleneck motivates an architectural inversion, where high-power control and readout electronics are…
Thermodynamic Imperative
Standard quantum computing paradigms assume that minimizing temperature is the primary pathway to coherence, driving massive investment in millikelvin dilution refrigeration. However, a fundamental thermodynamic paradox remains unsolved: cooling capacity scales superlinearly with temperature…
THERMODYNAMIC STABILITY OF A FILAMENTARY VACUUM
The theoretical program of analogue gravity has established a robust kinematic correspondence between the propagation of excitations in condensed matter systems and the behavior of quantum fields in curved spacetime. This framework, developed over decades of research, posits that the geometric…
Thermodynamic Veto
The realization of commercially viable, fault-tolerant quantum computing is precluded not by engineering immaturity but by a fundamental percolation phase transition driven by correlated noise and thermodynamic constraints, which render the required system scales physically uncorrectable. The status…
