    "abstract": "This report surveys quantum error-correcting codes. As Preskill claimed, 21st\ncentury would be the golden age of quantum error correction. Quantum channels\nbehave differently from classical channels, so researchers face difficulties in\ndeveloping robust quantum codes. Fortunately, the classical error control\nmethods have been well developed. If we can learn many lessons from classical\ncoding theory, we can expedite the development of quantum codes. Scientists\nhave discovered that quantum error correction shares many concepts with\nclassical counterpart. Both quantum and classical coding schemes add redundancy\nto information to protect against noises. They also have similar conditions for\nerror detectability and correctability.",
