Quantum Error Correction: Introduction and [[2,1,1]] detection code

In this video, I discuss the classical repetition code and majority voting. Following this I talk about basic problems faced while performing quantum error correction. Then I discuss a simple code that takes two qubits into the encoder and performs a single syndrome measurement of one stabilizer. I show the syndrome extraction steps and motivate the idea of a stabilizer. #quantuminformation #quantumcomputing #quantumphysics
