Quantum Information
This is an optional course taken from the final year Physics Undergraduate course. A summary is given in the current MSc Handbook. Other documents for this course (example sheets etc) are stored on Blackboard. The list below is indicative of the type of material covered in this course (taken from the 2015-16 course).
Mathematical foundations of QI
No cloning theorem, pure states, mixed states etc, generalized measurements, general evolution under completely positive maps.
Quantum communication
Teleportation/dense coding, Bell inequalities, generic properties of two-party pure state entanglement, entanglement as a powerful and interesting resource, elements of classical information theory, von Neumann entropy, Schumacher coding, information transmission channels
Entanglement Theory
Basic properties of entanglement: characterization/verification, manipulation (mixed state entanglement, distillation) and quantification
Quantum computer science
Notions of computational efficiency, classical and quantum gates and circuits, Examples of quantum gate implementations in ion traps, cavity QED, photons. Quantum algorithms: Deutsch/Jozsa algorithm, Grover's algorithm
Building a quantum computer
Di Vincenzo criteria and critical analysis of the general requirements for the realization of QIP, Analysis of 2 promising architectures (e.g: ion traps, linear optics, superconducting qubits, quantum dots, spin chains,…)
Quantum Error Correction
Error correcting codes, how finite fault tolerant thresholds arise
