Quantum computers are based on a completely different principle than classical computers. The aim of this course is to explain this difference by showing how basic quantum computing algorithms work in practice. It is focused on the theoretical foundations, mathematical description, and practical testing of the resulting quantum circuits on real quantum computers and their simulators in the Qiskit environment.
As this field has been undergoing hectic progress recently, new research results are constantly being published. It is impossible to cover all these new developments in a short-term course, so this course contains just the fundamentals.
On the first day, there will be a brief introduction and clarification of quantum entanglement along with examples of its applications (e.g. quantum teleportation).
The second day will include an explanation of the principle of quantum superposition and its implementation in several quantum algorithms (Bernstein-Vazirani, Deutsch-Jozsa, Simon's, and Grover's).
Finally, on the third day, the quantum Fourier transform and practical examples of its use will be presented (quantum phase estimation, Shor's algorithm).
By the end of this course, participants should understand:
Basic knowledge of linear algebra, complex numbers, Python programming basics, Qiskit account, and (last but not least) a great imagination, because in the quantum world, many things are very different.
