Description

This repository contains the the data presented the draft "Universal monitored dynamics in multimode bosonic systems" (arxiv:2603.13125).  The data shown here is divided into two types: the ideal dataset (fig. 2 and figures in SI section 1) and the noisy dataset (fig. 4 and SI figs 12, 13).

The ideal dataset may be found in the "boson-repo-zip.zip" file.  The "main" and "si" folders contain both data and plotting scripts, while the "scripts" directory provides some example code that was used to generate the dataset.

The noisy dataset may be found in the "Data_noise.zip" file.  A description of the data organization is provided in "Data_note.pdf", as is the plotting script "Plotting_clean.ipynb".

Abstract

We propose a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics. In this experimental setting, we construct several bosonic models comprising brickwork circuits built from beam-splitter gates, local parity measurements, and optional on-site Hubbard interactions, and diagnose their monitored dynamics via ancilla purification and a learnability-based probe. Under parity measurements, generic gate sets exhibit behavior that is largely consistent with a conventional measurement-induced phase transition, while a special class of beam-splitter circuits shows an apparent critical-like high-measurement regime in which purification times scale linearly with system size. We show that for realistic noise, gate, and measurement rates, these signatures are observable with near-term circuit QED hardware.
