Special announcements
No prerequisites in quantum mechanics and/or information theory are needed.
A draft of course notes will be updated weekly here draftDec14.pdf.
This is a 4 credit course. Exam form is oral.
Objectives
The support of information is material. Today one is able to manipulate matter at the nanoscale were quantum behavior becomes important. It is possible that ultimately information processing will have to take into account the laws of quantum physics. This course introduces the theoretical concepts and methods that have been developed in the last 25 years to take advantage of guenuine quantum resources. We will see how the concepts of bit, entropy, and Shannon’s theory are extended to the quantum domain. We will emphasize the role of entanglement which is a distinctly quantum feature. We will also see how useful quantum parallelism can be in the theory of quantum computation.
Outline: the course is divided in three parts
