Introductory lectures present some key features motivating the construction of quantum cryptosystems and computers. They also explain some major limitations due to error and decoherence. Even for the popular physical platforms based on super- conducting qubits (illustrated by the above photo of a quantum circuit from Martinis group at UCSB/Google) the development of quantum error correction schemes adapted to the physical contraints remains an open issue.

Lecture 1. Quantum cryptography and computation motivated by classical cryptography schemes.

Lecture 2. Quantum error correction with a quantum feedback perspective. Firstly, we present the three-qubit bit-flip and phase-flip codes and explain
