Merged summary
TL;DR - A Nature Photonics study experimentally shows that adaptive boson sampling with limited measurement-driven feedback can produce nonlinear photonic dynamics beyond passive linear optics. This helps bridge restricted boson-sampling systems and universal photonic quantum computers.
- Introduces nonlinear witnesses based on state-fidelity distances and Lie-algebra invariants.
- Demonstrates real-time feed-forward in a two-photon, two-mode setup using an integrated multiphoton platform.
- Uses post-selection to emulate more complex adaptive protocols with up to four input photons and multiple adaptation stages.
- Finds output states containing resources that cannot be deterministically prepared through equivalent linear-optical evolution alone.
