Phys 571.001  Quantum Computation Fall 2009 
Call No. 33784 (register for 3 credit hours)  
This course will cover a variety of topics related to quantum computation. The goal of the course is to master some of mathematical techniques and to convey some of the chief results of quantum computation theory. The topics to be covered are models of quantum computation, quantum algorithms, and quantum error correction.
This is the second semester of a twosemester sequence. The first semester focused on quantum information theory, covering the following topics: classical information, the Hilbertspace formulation of quantum mechanics, quantum states, quantum dynamics and measurements, quantum information, and quantum entanglement. It should be possible to take this course without having taken the first semester of the sequence. The course syllabus details the topics to be covered and provides a complete schedule for the course. It is also your gateway to the webbased material: lecture notes, special handouts, homework assignments, and solution sets, which are available as pdf files linked to the syllabus. The course assumes that you have a good background in linear algebra and some familiarity with the Hilbertspace formulation of quantum mechanics, including the description of quantum states as vectors in Hilbert space, observables as Hermitian operators, and time evolutions as unitary operators. The course is structured so that you could come up to speed on these things as the course progresses, but that would involve a bit of scrambling on your part to keep up. It will certainly be to your advantage if you have some familiarity with Dirac's braket notation for manipulating the linearalgebraic mathematical objects of quantum mechanics, and you are familiar with the Paulimatrix algebra for twostate quantum systems (qubits) and with the associated Blochsphere description of qubit quantum states. The course will be taught as a graduate specialty course; i.e., you are expected to be taking the course because you are interested in and want to learn the material. The course will be taught on two tracks, a graded track and an ungraded (credit/nocredit) track. There will not be any exams. Those registering for a letter grade will be expected to do the homework assignments. All students are welcome and encouraged to register for a grade. Students intending to do a PhD dissertation on quantum information are required to be on the graded track. (You should be familiar with the University deadlines for changing grading options.) Students who prefer the ungraded track should register for the CR/NC grading option. To receive a grade of CR, students need only to attend the lectures and show interest.

Office hours  Come see me. The semester is shaping up as one where although I will be very busy, I will be in the office Tuesday through Friday after about 10:00 am till perhaps 7:00 pm. I will try to stay at home on Mondays.
