Introduction

  • 1 minute

Quantum entanglement is a quantum phenomenon where two or more qubits are sharing information about their states, in such a way that qubits can't be described as individual subsystems. Quantum entanglement is a fundamental concept in quantum computing and it can be also a powerful tool.

In this module, you transfer the state of a qubit from one location to another without physically moving the qubit itself. This process, known as quantum teleportation, relies heavily on the principles of quantum entanglement. You'll use Q# and the Azure Quantum Development Kit to create and manipulate entangled qubits. To perform the teleportation, you use operations like Controlled-NOT (CNOT), Hadamard (H), and Pauli X and Z to create Bell states.

By the end of this module, you'll be able to:

  • Describe the concept of quantum entanglement.
  • Understand the quantum teleportation protocol.
  • Apply single-qubit and multi-qubit operations using Q#.
  • Create and manipulate entangled qubits using Q#.

Prerequisites

  • Basic understanding of quantum computing concepts.
  • Advanced knowledge of linear algebra and Dirac notation.
  • The latest version of Visual Studio Code.
  • The latest version of the Quantum Development Kit extension.
    • You can also open VS Code on the Web, which already includes the Quantum Development Kit extension.

To get the most out of this module, it's recommended to have the Explore quantum superposition with Q# module completed. This module introduces the basic concepts of Dirac notation, qubit states, and quantum gates.
