QUANTUM INFORMATION/QUANTUM COMPUTING
The teaching will be centred on hand-in exercises done by you, and detailed comments on the same
made by me. This means that we revert to pedagogy as it stood a century ago, when "Hermods" was around.
It will be possible to follow the course at-a-distance. In fact there will not be any lectures in the usual
sense, although there are complete lecture notes. There will however be discussion meetings at Albanova
twice a week, according to the schedule. You are STRONGLY encouraged to attend those if you can.
Good physics rests on talking to others.
The introductory meeting, on March 22, was on zoom.
A course program is here:
There will be question sessions at Albanova (FB:41) on Wednesdays and Fridays (13:15 until you run out of questions).
Lecture notes are here:
Notes for the course
(Updated, May 8.)
There will be "lab"-sessions on May 5, 10, and 12, at 9:30 in A4:3001. Please read the manual
Some extra remarks from last year include an
for the early pages of the notes, some remarks about how to handle tensor products
, and some remarks on notation .
There is a book, S. Stenholm and K.-A. Suominen: Quantum
Approach to Informatics, Wiley 2005, which presents things somewhat differently from the lecture
notes. I recommend you to have a thoughtful look at it.
For supplementary reading at an easy-to-follow level see for instance J. R. Price: An Introduction
to Information Theory, Dover 1980 (for classical information theory) and S. Aaronson: Quantum
Computing since Democritus, Cambridge UP 2013. There are many textbooks, including B.
Schumacher and M. Westmoreland: Quantum Processes, Systems and Information, Cambridge UP 2010
(introductory), D. Mermin: Quantum Computer Science, Cambridge UP 2007 (very clear-headed),
M. M. Wilde: Quantum Information Theory, Cambridge UP 2013 (advanced), and
M. A. Nielsen and I. L. Chuang: Quantum Computation and Quantum Information, Cambridge 2000
(advanced). If you feel a need to read up on classical probability, try H. Cramer:
Sannolikhetskalkylen och några av dess användningar (many editions, some in
For geometrical things, look at R. Penrose: The Emperor's New Mind (Oxford UP 1989) and
R. Penrose: Shadows of the Mind (Oxford UP 1994). Especially Chapter 6 of the former and
Chapter 5 of the latter. Chapter 2 of the former is a very good introduction to Turing
The manual for the lab session --- I think it should be called that --- is here:
Finally, a few more suggestions for reading:
paper" for the connection between the Fisher-Rao distance and quantum mechanics is
W. K. Wootters, Phys Rev D23 (1981) 357. Have a look (and when you read it, remember
that this had not been explained before).
A long story about "distinguishability measures", mostly in quantum theory, can be found in
PhD thesis. A more geometric way of looking at things can be found in a book
I coauthored, but that's even longer.
An interesting account of the Bell inequalities is I. Pitowsky, George Boole's 'Conditions of
possible experience' and the quantum puzzle, Brit. J. Phi. Sci 45 (1994) 95. I also very much
recommend the "invitation" to quantum information theory by Reinhard Werner
For the discovery of how partial transposition helps us to recognize entangled states, see
, and for the observation that this is really about positive
maps that are not completely positive see Horodeccy
. ("Horodeccy" is "Horodecki" in Polish plural form.)
It is interesting to read
own account of his algorithm, since it introduces a lot of perspectives.
