Photon Quantum Deterministic Simulation API is one of 9 APIs that [Photon Engine](https://apis.io/providers/photonengine/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Quantum, ECS, Deterministic, and Lockstep. The published artifact set on APIs.io includes API documentation.

Photon's deterministic, ECS-based simulation framework that ships player inputs (not state) across all clients in lockstep, re-simulating identically on every machine. Transport is the shared Photon Realtime protocol (UDP/TCP/WebSocket); Quantum also supports the same Room Lifecycle WebHooks as Realtime/Fusion.
