Foundational — QCore 6: Pre-Binary Sign Net Worker Beyond Quantum A-to-B, With SCADA Release — This article presents QCore 6 as the successor architecture to QCore V, preserving the pre-binary local worker while adding Sign Net custody, SCADA release, read-through M witness measurement, Sadovskii Spin First, upstream lattice carry, double-detour return, and endpoint verification into one runtime order. The central claim is that QCore remains outside the native Quantum A-to-B corridor: A-to-B, Bob verification, midpoint witness drains, binary handling, and SCADA command flow become client or bridge uses of a worker result rather than the original storytelling layer. QCore 6 classifies the richer object before ordinary binary, public-row, command-client, or endpoint authority becomes live. The worker freezes the run, declares custody, preserves typed-zero pressure, separates recognition from enforcement through SEB and MAP, releases only bounded survivors, and verifies exported endpoints through sealed capsules. The article also supplies a JSON-style replay template and falsifiable tests for SCADA custody, stored-anchor separation, 2.75 continuity, Sadovskii Spin First, lattice forecast, read-only M witness use, double-detour return, and full QCore 6 replay.

Critical — Quantum Read-Through Measurement. This article defines a transitional read-through measurement architecture in which midpoint M samples an A-to-B route without becoming the endpoint measurement authority. M is treated as a read-only witness surface: it may export a copied witness row, but it may not own the payload, repair the payload, rewrite branch identity, or decide Bob-side truth. The central contribution is the authority separation between witness sampling and endpoint certification. Multi produces raw partial reads, STLF writes the visible sign-or-zero ledger, SEB recognizes the row, and MAP enforces the permitted grade. This prevents a weak or partial read from being promoted by narrative repair. The paper also separates M as a useful stopgap bridge from Pre-Binary Sign Net as the stronger architecture. M can reduce B-side validation burden by catching route-side or A-side failures early, while Pre-Binary moves Sign Net classification to the front end before ordinary binary handling or late qudit-cell validation becomes authoritative. The included synthetic result supports the staged grammar by showing clean separation among Strong, Strong-to-Weak, Weaker, Hold, 0S continuity, and Refuse outcomes under fixed rules.
Critical — ZnO Triple Quantum Dots As Pre-Binary Qudit Custody. This article develops a qudit-first certification reading of a ZnO triple quantum dot platform before qubit read-down. The source reports few-electron triple quantum dots in ZnO heterostructures, gate-controlled interdot coupling, a two-dimensional electron gas interface, charge-sensing readout, and a QCA correlated-motion witness. The present framework treats QD1-QD2-QD3 as one pre-binary qudit capsule rather than as three immediate qubit endpoints. The article introduces an around-the-individual-dot-anchor route that preserves dot-facing charge evidence, interdot coupling, QCA middle behavior, lattice-facing ZnO interface support, sensor witness, and typed-zero custody as one carried triangulation. Materials-Qudit PTT, Dot-To-Lattice Detour, Read-Through Measurement, Spin First, three-frame return, Hilbert/TWA+ payback, and Second-Generation Hilbert typed-zero discipline are used to certify the richer triple-dot relation before any binary endpoint read consumes the result. The article is Critical because it blocks premature flattening of a multi-dot qudit object into qubit language and supplies a stricter route for preserving carrier relation, support, witness, and read-down custody.
Critical -- From Photon Cavity To Check-Branch Custody: Passive QEC, Metadata Repair, And Early Read-Only Certification This article uses passive quantum error correction of photon loss at breakeven as a source foothold for a broader certification problem. The source demonstrates a superconducting cavity system in which photon loss changes parity and engineered dissipation supports passive replacement, reaching a reported break-even point for the encoded qubit lifetime. The article then asks whether the middle of the correction process should be treated only as a hardware-repair problem or also as a custody and metadata-certification problem. The central contribution is the separation of live quantum payload from encoded metadata. The photon/cavity state remains the live carrier of the quantum data, while a check branch carries only parity, syndrome, address, time window, branch identity, support markers, custody hash, and repair rule. This metadata branch cannot recreate destroyed quantum data, but it may make partial degradation actionable while the encoded carrier remains recoverable. The article develops this into a cavity-side read-only architecture. Instead of waiting for Bob-side endpoint validation, the first witness surface is moved to the cavity, where the encoded object is formed and where degradation begins. Multi-zone witness reads, STLF token writing, SEB recognition, MAP enforcement, typed-zero returns, and QCore-style worker custody are used to classify repair, hold, release, downgrade, refusal, 0S continuity, or 0T blockage before endpoint validation becomes the main burden. The result is not a replacement for physical quantum error correction. It is a proposed software-governed metadata-custody overlay that may reduce unnecessary middle hardware burden, improve early refusal, preserve audit visibility, and move the architecture toward local cavity-side worker certification before photon-loss timeout.
Significant — This article, Logical Error Attribution to Sign-First Custody: Typed-Zero Control for Dual-Rail Superconducting Qubits, uses a significant and serious dual-rail erasure-qubit hardware result as the occasion to unify a sign-first chain built from Contain And Continue, Randomness, Rethinking Noise, Sign Net Detour, and Fingerprints in 3D. The paper argues that the key missing object is not another late logical-pathology story but a smaller post-gate control row written as committed sign, front-end 0T, or back-end 0S under frozen recognition, fixed enforcement, stored-anchor custody, and no-backflow. It then shows how bounded detour work in Richardson Subspace, typed-zero accounting, 3D protection, and QCore’s corridor-first horizon together provide a more portable and contract-grade answer than late diagnostic narration alone.
Foundational — Gate-On First: A Bidirectional Sign-Net Protocol for Controlled-Z Gate Certification with Typed-Zero, Mapped Support Matching, and D4 Custody. This article should be read as a reusable external-certification architecture for connecting device-independent quantum-gate evidence to Sign-Net decision custody. The protocol records the gate-on block first as a frozen, ungraded candidate while preserving the source-compatible certification order in which the identity-setting correlations establish the upstream reference structure before the unitary-setting evidence receives authority. Full device-independent and almost device-independent operation remain separate report classes, and the Sign-Net engine receives only committed external settings, outcomes, source and repeater records, isolation evidence, confidence intervals, and frozen reference definitions rather than hidden information from inside the tested gate. The article replaces literal Local-inside-Universal language with mapped support matching across distinct observations. A Local record containing four mapped items and a gate-on record containing ten items can establish four shared matches and six active-only items without treating the two physical conditions as simultaneously nested. A two-knob measurement then reads bottom-up Local somethingness represented in the gate-on candidate and top-down gate-on nothingness relative to the Local demand. These quantities use separate denominators and remain distinct from physical emptiness, unresolved missingness, (0T), and inherited (0S) custody. Cross-Chain Closure compares the opposed Local/identity records at the fixed (S=0) address and separately compares the returned gate-on block with the frozen first observation. D4 retains candidate evaluation, typed-zero review, mapped matching, final grading, and all onward promotion authority. D5 provides bounded recovery and Strong-to-Weak witness return, while D6 receives only D4-authored full-sign or Strong-to-Weak (0S) promotion. A fourteen-scenario Monte Carlo grammar test produces fifteen thousand baseline D6 promotions with zero false-physical certifications, zero unsafe promotions, and zero missed-certifiable outcomes inside the declared synthetic suite. A separate Weaker-to-D6 countertest produces five thousand false and unsafe promotions, directly fixing the promotion boundary while leaving Bell self-testing and physical device-independent implementation to upstream experimental work.
Scalable quantum processors require control, readout, feedback, calibration, and error correction to coexist under bounded latency and shared-resource constraints, whereas existing platforms typically optimize only a subset of these capabilities. This article presents QCORE (Quantum-Control-Oriented Real-Time Execution), a QPU-side digital control reference architecture positioned between the Host and a platform-specific analog/mixed-signal front end. QCORE separates task management, shared resources, hard-real-time execution, and long-timescale services into four hardware partitions. A fast-result sideband closes same-round feedback, a Measurement Packet provides a traceable measurement and service interface, and a common service-control skeleton, Tile-local QEC, and versioned safe-point commit organize calibration, error correction, and long-term state updates. Transaction-level, event-driven, and quantum-behavioral models are used for evaluation. At a background load of 0.8, the P99 latency of the shared Measurement Packet/Event feedback path is (1.984±0.004)Lmax. Closed-loop operation reduces the mean frequency error by 83.2%±0.8% and lowers the state-assignment error at maximum readout drift from 10.39%±0.54% to 5.37%±0.29%. No unsafe acceptance or mixed-version observation is observed in 100,000 configuration transactions, and Tile-local QEC reduces modeled global-boundary demand and yields a 2.08× capacity-normalized scaling estimate.
