I will give introduction to quantum error correction. I will describe stabilizer formalism and show how to construct topological error correction codes. Then I will present a procedure which enables encoding of qubits in them. I will describe holographic error correction codes and their relation to absolutely maximally entangled states. Finally I will show how one can find stabilizers for concatenated codes with the use of entanglement swapping.
