Introductory description

Quantum computing is an interdisciplinary field that lies at the intersection of computer science, mathematics, and physics. This computational paradigm relies on principles of quantum mechanics, such as superposition and entanglement, to obtain powerful algorithms.

Module aims

This module aims to provide a self-contained, comprehensive introduction to quantum computing, focusing on the design and analysis of quantum algorithms, as well as covering topics in quantum information and quantum cryptography, such as: quantum teleportation, quantum money, and post-quantum cryptography.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Quantum computing — motivation, foundations, and prominent applications.
Review of linear algebra in the context of quantum information, Dirac’s bracket notation, limitation of classical algorithms.
The four postulates of quantum mechanics, qubits, quantum gates and circuits.
Basic quantum algorithms I — Deutsch’s algorithm, analysing quantum algorithms, and implementing quantum circuits via QISKIT.
Basic quantum algorithms II — Simon’s problem and the Bernstein -V-azirani algorithm.
Grover’s quantum search algorithm, the BBBV Theorem, and applications of Grover’s algorithm.
RSA, and Shor’s integer factorisation algorithm.
Introduction to quantum cryptography (post-quantum security, quantum key distribution).
Introduction to quantum information (superdense coding, nocloning theorem, quantum teleportation) Applications (quantum money, the Elitzur-Vaidman bomb).

  • State the four postulates of quantum mechanics and their application to computation:- Design and analyse quantum algorithms.- Grasp the notions of quantum states, unitary evolution, measurements, andcomposite systems.- Restate the postulates in terms of density matrices.
  • Understand the principles of quantum information andquantum communication:- Understand quantum teleportation and its limits.- Describe the framework of quantum error-correcting codes.- Discuss Everett’s many worlds interpretation.
  • Analyse fundamental quantum algorithms:- Shor’s algorithm.- Grover’s search.- The Berstein-Vazirani algorithm.- Simon’s problem.- The Deutsch-Jozsa paradigm.
