Start Your Engines: From Quantum Random Numbers to Teleportation and Super Dense Coding

This chapter takes you on a journey about three remarkable information processing capabilities of quantum systems. We start with one of the simplest procedures by exploring the fundamentally random nature of quantum mechanics as a source of true randomness. Next, the chapter looks at perhaps two exuberant but related procedures called super dense coding and quantum teleportation. In super dense coding, you will learn how it is possible to send two classical bits of information using a single qubit. In quantum teleportation you will learn how the quantum state of a qubit can be recreated by a hybrid classical-quantum information transfer procedure. All algorithms include circuit design for the IBM Quantum Composer as well as Python and QASM code. Results will be gathered for display and analysis, so let’s get started.
