Z6 Topological Shielding
Passive Decoherence-Free Subspaces — Live on ibm_fez
A unified system for passive preservation of quantum information. Empirically validated on commercial superconducting architecture (ibm_fez Heron r2). 95.2% average GHZ fidelity across 57,344 physical shots, utilizing 1D Z6 alternating parity invariants to bypass active QEC overhead entirely.
Topological Z6 Parity Shield
Initializes linear chain into alternating mathematical invariant. Entanglement established exclusively through nearest-neighbor CX, enforcing strict compliance with IBM heavy-hex and preventing routing SWAP gates.
Thermodynamic "Dark" Memory
Reverses symmetric storage vulnerabilities by mapping data such that majority of physical qubits remain in ground state |0⟩. Thermal relaxation from dilution refrigerator actively preserves, rather than degrades, lattice baseline — observed as >80% ground-state bias in prior crucible tests.
Zero-SWAP Parity Compression
Validates macroscopic state integrity via linear nearest-neighbor cascade. Global parity checksum compressed into single terminal anchor qubit, bypassing compounding ~1.5% SPAM limits. Empirical static error boundary ~24.4% isolated in earlier 3µs tests; current GHZ runs show dynamic decoherence halted.
