Introduction

In our current digital world, everything, from computing devices to communication channels, is represented as 0s and 1s. The “information” that these bits can present has been well studied in the field of classical information theory. For example, we know the capacity and limits of data compression and the rate of reliable communication over noisy channels. Recently, perhaps due to the excitement of quantum computation, these ideas in information theory have been extended to the quantum world, leading to the field of quantum information theory.

In this paper, we would like to introduce the quantum counterparts of some of the key ideas we studied in the course, including the quantum entropy measure, quantum source encoding, and touch briefly on quantum channels.

Outreach

Our outreach project is called “QUTE” (“Q” for quantum / qubits, “U” for uncertainty / unitary, “T” for tensor / teleportation, and “E” for entropy and entanglement). The technality of quantum information theory was hidden, and the project instead focused on highlighting the difference between the quantum and classical setting.
