help with an article

Hi everybody!
I'm writing an article in portuguese, but the abstract must be in English too.
Can someone help me? I want to know if it's right.

ABSTRACT: It shows superficially the principles of quantum mechanics that are used in the quantum information treatment and in the quantum computation research. It also makes an introduction to the Shor’s quantum algorithm (Factorization and Order Determination) and analyses the effects of quantum computation in the information security.
KEYWORDS: Quantum Computing. Information Security.

I will be grateful for any help. Thanks!

Everything looks good minus using "the" a lot. Unlike in Portugese, in English, the definite article "the" isn't used all of the time. It can be tricky to figure out when to use it and when not to for those with native languages that use it in front of most every noun - and even as a native English speaker, I can't fully explain why it's not "the information security" as opposed to "information security." (And the other two places I nixed.) Though I believe that it's probably having to do with how "information security" in general is fairly abstract. "The" usually refers to things that are very specific, such as "the book," or "the table." But if you are trying to say "the information security" it needs to be something that is definite. The way you are trying to use it isn't definite - it's a concept that doesn't have form yet.
