Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
EntanglementenablesQubitEstablished
Entanglement links qubits.
Mechanism: Entangled qubits share one joint state, a correlation quantum algorithms exploit for speed.
Enables · leads to
Grover's algorithmdepends onQubitEstablished
It searches with qubits.
Mechanism: Grover's algorithm amplifies the right answer's amplitude for a quadratic search speedup.
Quantum advantagedepends onQubitEstablished
Enough good qubits beat classical.
Mechanism: Quantum advantage is reached when a device's qubits solve a task no classical computer feasibly can.
Shor's algorithmdepends onQubitEstablished
It runs on qubits.
Mechanism: Shor's speedup exploits quantum interference across many qubits.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 7 → 19 → 38 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 7 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
