Prequisites: Familiarity with basic Linear algebra and Probability
Course Objective:
The course aims to serve as an introduction to the quantum computational model with the goal of understanding basic quantum algorithms and analyzing them. The course also addresses limitations of quantum algorithms and introduces the necessary tools and techniques to prove the same.
Course Content:
Brief review of linear algebra and probability preliminaries. (1 lecture)
Basic notions: Qubits, Diracâ€™s notation, operations on qubits, unitary operators and matrix representations. Single qubit gates - Hadamard, Rotation, NOT and Phase gates. Multi-qubit gates â€“ CNOT, Toffoli. SWAP test. (3 lectures)
Quantum circuits, Church-Turing hypothesis and extensions, Universality of quantum circuits (1 lecture)
No cloning theorem, Relation to probabilistic computation, Bell pair, EPR paradox (5 lectures)
Quantum Oracles, Quantum algorithms for promise problems: Deutsch-Jozsa, Bernstein-Vazirani and Simon (4 lectures)
Phase estimation, Eigenvalue estimation and Quantum Fourier Transforms. (6 lectures)
Searching in an unstructured database: Grover search â€“ geometric and diffusion views. Quantum walks. Optimality of Grover search. (4 lectures)
Shorâ€™s algorithm for factoring. Order finding, Period finding, Reductions. (7 lectures)
Quantum algorithms for hidden subgroup, element distinctness, collision detection and triangle counting problems. (4 lectures)
Lower bounds. Adversary method, polynomial method, quantum query complexity (3 lectures)
Quantum Complexity Theory. Complexity class BQP and its connections to classical computation. (2 lectures)
Advanced topics in quantum computation (if time permits) like Noisy intermediate scale quantum models, quantum error correction and quantum proofs for classical theorems (2 lectures)
Learning Outcomes:
- Being able to analyze simple quantum algorithms and argue optimality.
- Familiarity with 1-qubit / 2-qubit gate operators and ability to design simple quantum circuits.
- Ability to read and understand recent results as well as research papers on quantum algorithms
