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…
Differential Einthoven‑Inspired Readout for Superconducting Qubit Measurement: Theory and Projected Fidelity Gains
Readout error dominates the overhead of quantum error correction in superconducting processors, limiting logical error rates and scaling prospects. Existing dispersive readout chains suffer from common‑mode disturbances such as amplifier drift, thermal fluctuations, and stray coupling, which add…
Planar Fluxonium‑Controlled Bosonic Error Correction: A Quantitative Error‑Budget Reassessment (Corrected Version)
Bosonic quantum error correction (QEC) encodes a logical qubit in a single harmonic oscillator, promising fault tolerance with far fewer physical components than qubit‑based surface codes. Recent planar demonstrations using a heavy fluxonium ancilla report a bit‑flip lifetime of…
Continuous Signal Processing for Josephson Junction Readout
The prevailing architecture of superconducting quantum information processing relies heavily on the Josephson junction, yet its dual role as both a qubit-defining non-linear inductor and a latching readout element creates a fundamental tension in measurement dynamics. While the former enables the…
