Analysis of a Quantum Error Correcting Code using Quantum
... Our model of a quantum error correction system consists of three processes: Alice, Bob and Noise. Alice wants to send a qubit to Bob over a noisy channel, represented by Noise. She uses a simple error correcting code based on threefold repetition [13, Chapter 10]. This code is able to correct a sing ...
