Q-Code field experiments with zero installs: no Python, nothing to set up. Just open this page in Chrome or Edge on your laptop and tap the buttons.
Privacy: everything runs on your laptop. No audio, no scan data, and no result ever leaves this page — except what you choose to copy and paste to Quanta. The page makes exactly one kind of network request, and only when you press the quantum button: fetching public random numbers from the ANU quantum beacon. Nothing else ever phones home.
Honest limit, up front: browsers do not expose WiFi scans (privacy rule), so the WiFi part still needs the Python script. What works here: the acoustic field (speaker + mic, all browsers) and Bluetooth (Chrome/Edge). If the Bluetooth button says unavailable from a downloaded file, that is a browser security rule — the hosted version of this page fixes it.
The speaker plays tones, the mic hears the room answer. The room's response curve is its acoustic fingerprint. Move, rescan, and the field moves with you.
Scans nearby Bluetooth LE advertisements with signal strength — a second field fingerprint, from the laptop's own Bluetooth radio.
Browsers block WiFi scanning, so this part stays in
run_field.py (Windows built-in scan, zero installs beyond
Python itself). The acoustic + Bluetooth experiments above are the
no-install path.
Hold the quantum line: the acoustic and Bluetooth fields above are classical at room scale. This section is the genuinely quantum part, free, no install. The Australian National University runs a public quantum random-number beacon — vacuum fluctuations measured in a lab, streamed live. This button collapses a Q-Code field using those numbers: the outcome is decided by real quantum events, not your laptop's random-number generator.
Copy this JSON and paste it to Quanta — the loop continues: Quanta interprets the field and returns the next program.
