Quantum information science is an interdisciplinary field of research concerned with the encoding and manipulation of information in the state of a quantum system. This course will provide an introduction to the field, including aspects of classical information theory; the physics of measurement and evolution of finite-dimensional quantum systems; entanglement; and elements of quantum computation.
Typically 2 lectures per week.
Description of Summative Assessment:
Assessment: Unseen examination, comprising compulsory short questions and a choice of 1 from 2 long questions.
Reassessment: Reassessment of the main diet examination is normally available for students on PGT degree programmes if they do not achieve an overall course grade of C3 at their first attempt. Reassessment of the main diet examination is not normally available for students on Honours degree programmes.
Main Assessment In: April/May
The aims of this course are:
To provide an introduction to quantum information theory, including the necessary background in classical information theory, and the physics of finite-dimensional quantum systems.
To describe how to encode, manipulate and read-out information in a quantum system, and to discuss the relationship between physics and information processing.
To introduce quantum protocols such as teleportation, quantum key distribution, the principles of quantum computation and some examples of quantum algorithms.
Intended Learning Outcomes of Course
By the end of this course students will be able to:
Explain the difference between a bit, the carrier of classical information, and a qubit, the carrier of quantum information.
Give an example of a generalized quantum measurement and evaluate the probabilities of measurement outcomes.
Evaluate the evolution of a pure or mixed quantum state under a given quantum operation, perhaps represented as a quantum circuit.
Determine whether a composite pure state is entangled.
Perform advanced calculations in quantum mechanics.
Understand and explain important examples of quantum protocols including dense coding, teleportation, quantum key distribution, Grover's algorithm and Shor's algorithm.
Minimum Requirement for Award of Credits
Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
