Indiscernibility of quantum states
Jan van Neerven, Marijn Waaijer
This paper provides a systematic study of the operational idea that a quantum ``state'' is only defined up to what can be distinguished by a chosen family of observables. Concretel…

A relational critique of Bell locality
Jan van Neerven, Marijn Waaijer
This paper provides a systematic analysis of Bell experiments from the relational perspective, demonstrating that the apparent ``nonlocality'' of quantum mechanics stems from a pro…

Delayed choice experiments: An analysis in forward time
Marijn Waaijer, Jan van Neerven
In this article, we present a detailed analysis of two famous delayed choice experiments: Wheeler's classic gedanken-experiment and the delayed quantum eraser. Our analysis shows t…
