A single measurement of a quantum many-body system of bosons

TL;DR

This paper proposes an approximate method for simulating the results of a single-experiment density measurement on a bosonic many-body quantum state, effective when modes are macroscopically occupied.

Contribution

It introduces a novel approximation technique for simulating measurement outcomes in bosonic systems, applicable under specific occupation conditions.

Findings

The method accurately predicts measurement results in macroscopic occupation regimes.

It simplifies the simulation process for complex many-body bosonic states.

Abstract

Here I propose an approximate way of simulating the outcomes of a single-experiment density measurement that is performed on a state of N bosons. The approximation is accurate if occupation of single-particle modes is macroscopic.
