The delayed-choice eraser thought experiment poses the following dilemma: it seems that the choice we make now about whether or not to erase a particle's information somehow affects its past behavior.

In this video, Oxford PhD researcher Maria Violaris resolves the quantum eraser paradox — showing that we can fully understand the eraser without any backwards-in-time influence. Maria explains how to implement the thought experiment yourself on a quantum computer with Qiskit, revealing that the real origin of the delayed-choice eraser phenomenon is in quantum entanglement.
