The quantum eraser does not always erase

TL;DR

This paper offers a nonlinear perspective on quantum eraser experiments, challenging orthodox views by explaining why some experiments do not erase interference patterns, thus providing a new interpretation of quantum phenomena.

Contribution

It introduces a complex nonlinear approach to quantum eraser experiments, offering an alternative explanation that does not rely on traditional quantum mechanics concepts like complementarity or entanglement.

Findings

Nonlinear approach explains quantum eraser results intuitively.

Some experiments do not erase interference patterns despite which-path info.

Contradicts orthodox quantum mechanics but aligns with nonlinear quantum physics.

Abstract

In this paper we will first look at a particular quantum eraser setup to show that this type of experiments can be understood in an intuitive manner if we are willing to take a complex nonlinear approach, without the need to invoke Niels Bohr's complementarity or quantum entanglement between two particles. We will then discuss a recent experiment of the same type that does not erase the interference pattern when which-path information is available, and argue that this result is in clear contradiction with the orthodox interpretation of quantum mechanics but perfectly understandable in the framework of nonlinear quantum physics.
