Introduction to concept of error correction; motivation; differences between classical and quantum error correction; bit and phase flip errors; discussion of decoherence; notion of physical vs logical c/q-bits; repetition code; probability of bit flip errors in repetition code; quantum 3-qubit code for encoding one logical qubit and the circuit for generating the same from the physical qubit we want to encode
