RESUMO
Quantum error correction codes have been developed to enhance the reliability of the quantum hardware. The majority of the known quantum codes belong to the class of block codes, while quantum convolutional codes have been recently proposed. The class of unequal error protection (UEP) codes, well known in the theory of classical codes, has not been studied in the context of quantum codes. This study is the main objective of this dissertation. The concept of quantum separation vector is introduced as well as a technique to analyze the UEP property of quantum block codes for two classes of channels: bit flip and phase flip
