Comment on "Towards universal quantum computation through relativistic motion"

TL;DR

This paper critiques a previous proposal claiming to generate useful continuous-variable cluster states via relativistic cavity motion, clarifying that the actual states produced are not suitable for measurement-based quantum computation.

Contribution

It provides a critical analysis showing that the states produced in the original proposal are not the claimed cluster states and are not useful for quantum computation.

Findings

The proposed method does not generate the claimed cluster states.

The actual states produced are generally not useful for measurement-based quantum computation.

The critique clarifies the limitations of the original proposal.

Abstract

The work reported in arXiv:1311.5619v1 proposes to produce continuous-variable cluster states through relativistic motion of cavities. This proposal does not produce the states claimed by the authors. The states actually produced are in general not known to be useful for measurement-based quantum computation.
