Answer:
Edge computing is processing the data close to the origin. You can refer my other answer here for more detail Chetan Kumar's answer to Why has edge computing become so popular? What are the merits and demerits of edge computing as compared to cloud computing? .
Quantum computing is using quantum phenomena to do computing. Just like the gates maintain state (0/1), superposition and entanglement phenomena of quantum mechanics can be used to maintain states and perform computing.
