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.

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…
Parity-Protected Superconducting Qubits at 4 K: A Reconciled Thermodynamic Error-Budget Analysis
Scalable superconducting quantum computing is conventionally operated at millikelvin temperatures, where the cooling power available from dilution refrigerators is severely limited. This paper tests the conjecture that a thermodynamic bottleneck at millikelvin temperatures could be relieved by…
Thermodynamic Bottlenecks on Floquet Driving of Superconducting Matter: Quasiparticle Poisoning, Heat Extraction, and Design Rules
Floquet engineering—periodic modulation of a Hamiltonian to synthesize effective dynamics—is attractive for superconducting circuits and materials, but a driven superconductor is an open system: every absorbed drive photon must be dissipated into a cryogenic bath, and above-gap absorption breaks…
Superconductivity Quadrangle
The engineering of robust, decoherence-resistant topological qubits is currently impeded by a fragmented approach to material design that often treats control parameters in isolation. This study introduces and computationally validates the “Superconductivity Quadrangle,” a unified framework…
Structural vs Driven Quantum Coherence
The pursuit of ambient superconductivity is hampered by a fundamental trade-off between active, energy-intensive control and passive, structural stability. Current literature lacks a unified framework that connects the thermodynamic costs of information, substrate complexity, and the disparate…
Twisted Cuprate Twistronics and the Thermodynamic Scaling of Topological Quantum Computation
The induction of a 25 meV chiral topological gap in 45-degree twisted Bi-2212 heterostructures enables intrinsically protected quantum computation at 4 Kelvin, effectively resolving the thermodynamic and input-output bottlenecks that constrain current millikelvin superconducting architectures.
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…
TOPOLOGICAL HYDRODYNAMICS AND THE SPECTRAL GAP
Standard quantum field theory conceptualizes the vacuum as a probabilistic void, yet phenomenological isomorphism with superfluid Helium-3 suggests a deeper hydrodynamic ontology. While this topological substrate theoretically supports analog computation via vorticity, the practical realization is…
