 6. 초록 :  The goal of this series of lectures is to present some recent results in QIT which make use of
             random matrices. After an introduction to random matrix theory, I will present the method of moments,
             one of the most successful methods used to study the spectra of large random matrices. This will be
             the occasion to discuss integration over Gaussian spaces and over unitary groups. On the QIT side,
             I will focus on two main topics, random quantum states and random quantum channels. I will then
             prove two recent results, one on the asymptotic eigenvalue distribution of the partial transposition of
             random quantum states, and another on the output set of random quantum channels. Both will
             require some terminology and results from free probability, which will also be discussed in detail.
