Response to `Comment on "Experimental demonstration of a universally valid error-disturbance uncertainty relation in spin measurements" '

TL;DR

This paper refutes a previous comment on a quantum uncertainty relation experiment, clarifying that the comment's argument is based on an improper basis and is therefore incorrect.

Contribution

It provides a rebuttal to a critique of a quantum measurement uncertainty relation, reaffirming the validity of the original experimental results.

Findings

The comment's argument is based on an improper basis.

The original uncertainty relation experiment remains valid.

The authors disagree with the critique's conclusion.

Abstract

Here, we reply to the comment by Y. Kurihara. We show that the argument by the author is on an improper basis and thus disagree with his opinion.
