What is a random quantum walk and how are they used with quantum gates?

TL;DR

explanation of a random quantum walk with regards to quantum logical gates

I am an undergraduate doing research on QC/QI. My current topic to learn is continuous-time quantum walks, but first I must learn the random quantum walk. That being said, I was wondering if someone could simply explain what a random quantum walk is and then explain how they could be useful with quantum logical gates. I am familiar with the classical random walk already.

have you googled, this is not a PF type question, and seems impractical for undergrad generally. But who knows what your profs have in mind.
