One quote:
"We’ll use special mathematics – complex numbers and linear algebra (vectors and matrices). Unfortunately, most high school mathematics curricula around the world do not teach linear algebra. It’s not very complicated. It’s really just a different and clever way to add and multiply numbers together, but it’s a very powerful tool."
"The Quantum Cryptography School for Young Students (QCSYS) is a unique, eight-day enrichment program for students hosted by the Institute for Quantum Computing (IQC) at the University of Waterloo. QCSYS will run August 10-17, 2018 with students arriving August 9 and departing August 18.
The school offers an interesting blend of lectures, hands-on experiments and group work focused on quantum cryptography"

>Can I still apply if I am currently in grade 12?
>Yes. If you are currently in grade 12 and you are attending university or college in the fall 2018 you are still eligible to attend the Quantum Cryptography School for Young Students (QCSYS).
So, high school students. Material looks accessible enough and well presented.

If you don't know what quantum computation is or why it's important, then you have a lot of catching up to do.
