This course covers the basic (i.e., easiest) quantum algorithms.

After a review of quantum mechanics to the extent that is necessary for quantum algorithms, we will discuss the quantum circuit model for universal (fault-tolerant) quantum computing. From there, we will venture to increasingly complex quantum algorithms. We start with the Fourier transform based algorithms (Deutsch-Josza, and Simon’s algorithms, Quantum Fourier Transform, Fourier Sampling, Quantum Phase Estimation) which allows us to discuss Shor’s algorithm. We then proceed to amplitude amplification (Grover’s algorithm) and amplitude estimation. The course concludes with an outlook where we apply all the techniques learned in the semester to discuss a baby-version of the quantum linear system solver.

There will be two lecture classes per week, so that there’s sufficient time to work out lots of example quantum calculations in class.
