Quantum Communication

By IntroBooks Team

Quantum communication is an aspect of quantum information
science, which is a study based on the fact that information
sciences depend mainly on quantum effects in physics. It
involves several experimental topics in quantum physics
including computational models. It also covers areas of quantum
physics that can be carried out using quantum information and
those that cannot. In this script, you will learn about the
various subfields that can be found under quantum
communication. You will equally learn about the several
applications of quantum communication to the day to day
activities of humans. Also in this script, we will review the
present state of quantum communication research and what the
future direction is in this field of science. We are equally going
to place special emphasis on quantum network as well as
quantum key distribution.

PREFACE

Quantum communication is an aspect of quantum information science, which is a study based on the fact that information sciences depend mainly on quantum effects in physics. It involves several experimental topics in quantum physics including computational models. It also covers areas of quantum physics that can be carried out using quantum information and those that cannot. In this script, you will learn about the various subfields that can be found under quantum communication. You will equally learn about the several applications of quantum communication to the day to day activities of humans. Also in this script, we will review the present state of quantum communication research and what the future direction is in this field of science. We are equally going to place special emphasis on quantum network as well as quantum key distribution.

INTRODUCTION

Quantum Communication is the act of conveying a quantum state from one location to another. The traditional name of the receiver is Bob, while that of the sender is Alice; it is another way of saying the quantum state is transferred from point A to B. Basically, quantum state is used in coding quantum information and the codes are referred to as qubits; this is in agreement with the 2D Hilbert Spaces. If certain tasks are carried out using classical information, the outcome may be far from being efficient compared to when such tasks are carried out using quantum information. The best form of quantum state is called Quantum Key Distribution (QKD).

Quantum communication has completely changed the way humans think as regards quantum physics. The very first protocol for quantum communication was established in 1984 and 1991. It generated interest from researchers from various fields of experimental and theoretical physics. Researchers in the fields of computer sciences
