Qubit Zoo Index MOC

Top-level navigation for the Qubit Zoo by technology family.

Family MOCs

Start with a family MOC when you want modality-local comparisons.
Jump to Evergreen notes when you want mechanism-level synthesis that cuts across families.
Treat Reference notes as evidence nodes, not the main conceptual layer.

Start in color-center-moc for the benchmark room-temperature defect-spin story centered on nv-center-qubit.
Move to spin-photon-moc when the real comparison is remote entanglement, photon indistinguishability, or telecom-native links via siv-color-center-qubit and t-center-qubit.
Use divincenzo-criteria as the common scorecard, then coherence-time-hierarchy to track where each platform parks the cost: local coherence, cryogenic overhead, or photonic interface quality.

Use super-semi-moc when the same InAs/Al or Josephson-weak-link hardware is being used for tunable circuit physics, Andreev-spin control, or protected-circuit variants like ferbo-qubit.
Switch to topological-moc when the decisive claim is nonlocal parity encoding or a topological superconducting channel, as in majorana-topological-qubit, planar-josephson-junction-qubit, and tetron-qubit.
Keep josephson-junction-as-nonlinear-element and spin-orbit-coupling-for-qubit-control as the shared mechanism notes, then use threshold-theorem to judge whether the topological branch actually earns its overhead-reduction promise.

Start in superconducting-moc when the win is being claimed at the device layer: bosonic encodings, protected circuits, cat-bias engineering, or erasure-converting superconducting encodings all live there first.
Move to cross-platform-moc when the real comparison becomes logical-overhead strategy, decoder assumptions, or systems architecture via erasure-qubit, surface-code-logical-qubit, color-code-logical-qubit, and classical-control.
Use bosonic-code-hierarchy, noise-bias-and-asymmetric-error-channels, erasure-error-vs-pauli-error, and threshold-theorem as the four-note bridge from hardware mechanism to architectural consequence.

Preserve full Zoo → Evergreen coverage as new entries land, rather than treating coverage itself as an open cleanup target.
Prefer curated cross-family routes when the reviewer is already clean: navigation quality now matters more than raw metric movement.
Keep family MOCs lightweight above the marker, but preserve real synthesis below it.
