You should state the name of the topic or project in your first sentence so the reader will know what you are referring to. The word "the" should not be in front of " quantum in the first sentence, both instances.,Shor's",or information.
Your Abstract should read like the one below.
ABSTRACT: It (what?) shows superficially the principles of quantum mechanics that are used in quantum information treatment and quantum computation research. It also makes an introduction to Shor’s quantum algorithm (Factorization and Order Determination) and analyses the effects of quantum computation in the information security.
KEYWORDS: Quantum Computing. Information Security.
