Time Dilation in Quantum Systems and Decoherence: Questions and Answers

Understand

Recent work has shown that relativistic time dilation results in correlations between a particle's internal and external degrees of freedom, leading to decoherence of the latter.

• In this note, we briefly summarize the results and address the comments and concerns that have been raised towards these findings.
• In addition to brief replies to the comments, we provide a pedagogical discussion of some of the underlying principles of the work.
• This note serves to clarify some of the counterintuitive aspects arising when the two theories are jointly considered.
