402-0448-00L | Quantum Information Processing | 10 credits | 3V + 2U | J. Home, R. Renner | |
Abstract | The course is an introduction to quantum information processing. It covers the basic theory of quantum information and quantum computation as well as experimental aspects. | ||||
Objective | The goal is to acquire a good understanding of the ideas underlying quantum information processing. The course is also a preparation for subsequent more specialised courses in the area of quantum information science. | ||||
Content | The course starts with a treatment of key features of quantum theory that are relevant for information processing (such as quantum entanglement and non-locality). It covers basic communication tasks (quantum teleportation, entanglement swapping, key distribution, and distributed computation) as well as models of computation (e.g., the gate model) and algorithms (Deutsch-Jozsa and Shor). Further core topics are decoherence, quantum error correction, and fault tolerant quantum computation. | ||||

402-0492-00L | Experimental Techniques in Quantum and Electro-Optics Does not take place this semester. | 6 credits | 2V + 1U | J. Home | |
Abstract | We will cover experimental issues in making measurements in modern physics experiments. The primary challenge in any measurement is achieving good signal to noise. We will cover areas such as optical propagation, electronics, noise limits and feedback control. Methods for stabilizing frequencies and intensities of laser systems will also be described. | ||||
Objective | I aim to give an in depth understanding of experimental issues for students wishing to work on experimental science. The methods covered are widely applicable in modern physics, since light and electronics are the primary methods by which measurements are made across the field. | ||||
Content | The course will cover a number of different areas of experimental physics, including Optical elements and propagation Electronics and Electronic Noise Optical Detection Control Theory Examples from a modern quantum information laboratory will be discussed and illustrated through active devices in the lecture. | ||||
402-0498-00L | Cavity QED and Ion Trap Physics Does not take place this semester. | 6 credits | 2V + 1U | J. Home | |
Abstract | This course covers the physics of systems where harmonic oscillators are coupled to spin systems, for which the 2012 Nobel prize was awarded. Experimental realizations include photons trapped in high-finesse cavities and ions trapped by electro-magnetic fields. These approaches have achieved an extraordinary level of control and provide leading technologies for quantum information processing. | ||||
Objective | The objective is to provide a basis for understanding the wide range of research currently being performed on fundamental quantum mechanics with spin-spring systems, including cavity-QED and ion traps. During the course students would expect to gain an understanding of the current frontier of research in these areas, and the challenges which must be overcome to make further advances. This should provide a solid background for tackling recently published research in these fields, including experimental realisations of quantum information processing. | ||||
Content | This course will cover cavity-QED and ion trap physics, providing links and differences between the two. It aims to cover both theoretical and experimental aspects. In all experimental settings the role of decoherence and the quantum-classical transition is of great importance, and this will therefore form one of the key components of the course. The topics of the course were cited in the Nobel prize which was awarded to Serge Haroche and David Wineland in 2012. Topics which will be covered include: Cavity QED (atoms/spins coupled to a quantized field mode) Ion trap (charged atoms coupled to a quantized motional mode) Quantum state engineering: Coherent and squeezed states Entangled states Schrodinger's cat states Decoherence: The quantum optical master equation Monte-Carlo wavefunction Quantum measurements Entanglement and decoherence Applications: Quantum information processing Quantum sensing | ||||
