Photon Quantum is a high-performance deterministic ECS (Entity Component System) framework for online multiplayer games made with Unity.

It uses a method called predict/rollback, which is ideal for latency-sensitive online games like action RPGs, sports games, fighting games, FPS and more.

Quantum helps developers write clean code. It decouples simulation logic (Quantum ECS) from the view/presentation (Unity), and takes care of the network implementations specifics (internal predict/rollback + transport layer + game agnostic server logic).
