| Learning Outcomes: |
After taking the section on networks, the student should be able to:
芒锟铰escribe uses of networks in at least 2 different areas of science and technology;
芒锟铰efine, quantify and interpret some simple measures of network structure;
芒锟铰xplain methods for calculating more complex measures of network structure;
芒锟铰erive and interpret structural measures for simple model networks;
芒锟铰utline the key features of illustrative dynamic network models.
After taking the section on quantum information the student should be able to:
芒锟铰xplain that information is physical, and critically appraise how this alters from the classical to quantum domain;
芒锟铰xplain in detail the concept of quantum entanglement, the EPR paradox, experimental tests of Bell's inequalities;
芒锟铰llustrate uses of entanglement in quantum information protocols, such as quantum cryptography, dense coding and teleportation.
|
| Synopsis: | You will be introduced to two major topics in 21st century science: networks and quantum information. You will see how a wide range of systems of interacting objects, from insect colonies to the internet, can be analysed and modelled as a network of nodes connected by edges. Your mind will be boggled by quantum entanglement, the EPR paradox and Bells inequalities, and you will discover what Alice, Bob and Eve have been getting up to!
