Quantum measurement with chaotic apparatus

TL;DR

This paper presents a quantum measurement model where a chaotic-like dissipative oscillator simulates the collapse of a qubit state, linking chaotic dynamics with quantum measurement.

Contribution

It introduces a dissipative quantum model that connects chaotic oscillator behavior with the quantum measurement process, offering new insights into measurement dynamics.

Findings

Chaotic-like trajectories emerge during qubit measurement.

The model links classical chaos with quantum state projection.

Damped quantum oscillators can simulate measurement outcomes.

Abstract

We study a dissipative quantum mechanical model of the projective measurement of a qubit. We demonstrate how a correspondence limit, damped quantum oscillator can realise chaotic-like or periodic trajectories that emerge in sympathy with the projection of the qubit state, providing a model of the measurement process.
