This paper critiques Weber et al.'s claim that Ohm's law persists at the atomic scale, highlighting issues in data interpretation and questioning the relevance for quantum computing applications.

Contribution

It provides a critical analysis of the experimental interpretation and implications of atomic-scale conductance studies, emphasizing the need for rigorous data analysis.

Findings

Identifies deficiencies in conductance data interpretation

Questions the relevance of metallic structures for quantum computing

Highlights the importance of systematic analysis in atomic-scale transport

Abstract

The recent article "Ohm's Law Survives to the Atomic Scale" by Weber et al. [Science 335, 64 (1021)] reveals ohmic transport in quantized P-in-Si wires. We argue that their results have two main deficiencies: (a) the interpretation of conductance data is inadequate for serious systematics; (b) metallic-like structures hold few implications for quantum computing.
