Spec. course "Quantum computing"
Lecturer: Prof. O.N.Granichin
Students: 5 year, computer science department
Summary:
"Computer science" will be
significantly changed because size of elementary units of modern computers
decrease on 10-30% per year. After several years we'll have elementary units of
computer device by 100-200 A (0,01-0.02 micron).
This kind of device will not be capable to operate with usual bits {0,1}.
Internal nature of information will be changed. The new devices will operate
with "wave function" instead "digit". The new point of view
on the process of calculation needs in new math basement. On the one hand, it causes the replacement basic classical
(not quantum) algorithms, and, on the other hand, enables closely to be risen
to the solution of problems of “artificial intelligence”.
Themes of the course:
- Perspectives of
development of computer facilities. Specialized devices for the fast
solution of many-dimensional problems.
- Model of quantum
calculations.
- Quantum
parallelism. Deutsch problem.
- Search in a data
base (Grover’s algorithm).
- P.Shor’s algorithm
of a factorization.
- Teleportation of
quantum bits.
- Randomized algorithms of
stochastic approximation for the solving of multidimensional optimization
problems.
