Josephson-junction nonlinearity

The nonlinear circuit element that makes distinguishable superconducting-qubit transitions possible. This candidate isolates the cited result from broader claims about scaling, fault tolerance, manufacturability, economics, and useful computational advantage.

Bounded definition

The nonlinear circuit element that makes distinguishable superconducting-qubit transitions possible.

What the cited work establishes

The paper proposes and analyses strong coupling between superconducting qubits and microwave transmission-line resonators, including dispersive measurement and mediated interaction mechanisms.

The models, apparatus, protocols, datasets, and comparisons reported in Cavity quantum electrodynamics for superconducting electrical circuits: An architecture for quantum computation.

Claims: urn:maha:claim:josephson-junction-nonlinearity

What remains a separate question

Circuit nonlinearity does not establish low loss, stable fabrication, or a scalable control window.

It is an architecture and modelling paper; it does not establish yield, processor-scale control, fault tolerance, or a universal performance level.

Connected domain graph

Typed dependencies preserve publication state.

Only independently canonical records receive public links and relation statements. Draft graph topology remains private.

Scope
The models, apparatus, protocols, datasets, and comparisons reported in Cavity quantum electrodynamics for superconducting electrical circuits: An architecture for quantum computation.
Boundary
Circuit nonlinearity does not establish low loss, stable fabrication, or a scalable control window.
Uncertainty
No platform-independent uncertainty interval exists; numerical values remain attached to the source experiment or model and its stated assumptions.
Replication
This candidate records one bounded source package. Independent replications and contradictory measurements must be compiled as separate records before maturity is upgraded.
