The Puzzle of Empty Bottle in Quantum Theory

TL;DR

This paper explores how the mere presence of a measuring device can alter quantum state evolution without actual measurement, raising questions about the completeness of quantum theory.

Contribution

It introduces the concept of 'shadowing' effect, showing that measurement apparatus can influence quantum states even without measurement, challenging traditional views.

Findings

Measurement apparatus affects quantum states without measurement

Shadowing effect demonstrates deformation of quantum evolution

Raises doubts about quantum theory completeness

Abstract

We discuss an extremely simple effect of 'shadowing' where the very existence of the measuring apparatus deforms the evolution of quantum states even if the measurement is never preformed. In spite of strange intuitive aspects, it might be related to some recent doubts about the completeness of quantum theories.
