The Projection Postulate of Quantum Mechanics on the Lightcone

TL;DR

This paper explores a novel interpretation of the quantum projection postulate, proposing that wavefunction collapse occurs along the lightcone, which could impact our understanding of quantum measurement and causality.

Contribution

It introduces a lightcone-based collapse interpretation of the projection postulate, offering a new perspective on wavefunction collapse in quantum mechanics.

Findings

Wavefunction collapse can be modeled along the lightcone.

The lightcone interpretation aligns with relativistic causality.

Potential implications for quantum measurement theory.

Abstract

We discuss an interpretation of the projection postulate that implies collapse of the wavefunction along the lightcone.
