AbstractThe course will cover the key concepts and ideas of quantum information processing, including descriptions of quantum algorithms which give the quantum computer the power to compute problems outside the reach of any classical supercomputer. Key concepts such as quantum error correction will be described. These ideas provide fundamental insights into the nature of quantum states and measurement.
ObjectiveWe aim to provide an overview of the central concepts in Quantum Information Processing, including insights into the advantages to be gained from using quantum mechanics and the range of techniques based on quantum error correction which enable the elimination of noise.
ContentThe topics covered in the course will include
1. Entanglement
2. Circuits, circuit elements, universality
3. Efficiency ideas, Gottesmann Knill

AbstractIntroduction to experimental systems for quantum information processing (QIP). Quantum bits. Coherent Control. Measurement. Decoherence. Microscopic and macroscopic quantum systems. Nuclear magnetic resonance (NMR). Photons. Ions and neutral atoms in electromagnetic traps. Charges and spins in quantum dots and NV centers. Charges and flux quanta in superconducting circuits. Novel hybrid systems.
ObjectiveThroughout the past 20 years the realm of quantum physics has entered the domain of information technology in more and more prominent ways. Enormous progress in the physical sciences and in engineering and technology has allowed us to build novel types of information processors based on the concepts of quantum physics. In these processors information is stored in the quantum state of physical systems forming quantum bits (qubits). The interaction between qubits is controlled and the resulting states are read out on the level of single quanta in order to process information. Realizing such challenging tasks is believed to allow constructing an information processor much more powerful than a classical computer. This task is taken on by academic labs, startups and major industry. The aim of this class is to give a thorough introduction to physical implementations pursued in current research for realizing quantum information processors. The field of quantum information science is one of the fastest growing and most active domains of research in modern physics.

AbstractWe 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.
ObjectiveI 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.
ContentThe 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.
402-0498-00LCavity QED and Ion Trap Physics Information 6 credits2V + 1UJ. Alonso Otamendi, J. Home
AbstractThis 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.
ObjectiveThe 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.
ContentThis 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

The quantum optical master equation
Monte-Carlo wavefunction
Quantum measurements
Entanglement and decoherence

Quantum information processing
Quantum sensing
