## Key points

- Antoine Suarez argues that the three main interpretations of quantum mechanics support the Principle Q (Quantum)
- Principle Q states that not all factors relevant to physical phenomena are contained within space-time
- Born's rule is underpinned by Principle Q
- Suarez suggests that Principle Q may be the best way to define quantum mechanics from more fundamental principles
- Quantum mechanics has unique features such as superposition and entanglement
- Different interpretations of quantum mechanics have attempted to make sense of these features, ultimately leading to the emergence of Principle Q
- While Principle Q has been supported by various interpretations of quantum mechanics, it remains controversial among physicists who adhere to a more traditional view of physics as being solely concerned with space-time phenomena
- Suarez argues that this view may be too narrow and limiting when it comes to understanding the true nature of reality
- Further research into exploring how Principle Q can provide a better understanding of physical phenomena beyond those limited by space-time constraints is suggested.

## Summary

In his paper "Defining what is Quantum: Not all what matters for physical phenomena is contained in space-time," author Antoine Suarez argues that the three main interpretations of quantum mechanics - Copenhagen, de Broglie-Bohm, and Many-Worlds - support the Principle Q (Quantum), which states that not all factors relevant to physical phenomena are contained within space-time. This principle underpins Born's rule as well. Suarez suggests that Principle Q may be the best way to define quantum mechanics from more fundamental principles. Suarez delves into the history and development of quantum mechanics, highlighting its unique features such as superposition and entanglement. He then explores how different interpretations of quantum mechanics have attempted to make sense of these features, ultimately leading to the emergence of Principle Q. The author notes that while Principle Q has been supported by various interpretations of quantum mechanics, it remains controversial among physicists who adhere to a more traditional view of physics as being solely concerned with space-time phenomena. Suarez argues that this view may be too narrow and limiting when it comes to understanding the true nature of reality. He concludes by suggesting further research into exploring how Principle Q can provide a better understanding of physical phenomena beyond those limited by space-time constraints.
