Welcome to Quantum Mechanics I

Why are there intrinsic probabilities for quantum event and how we get them from the quantum formalism? How do we describe quantum systems and how do we deal with their physical properties?

Welcome to Quantum Mechanics II

In the second introductory course, we explore further two-qubit state space and entanglement. The concept of indistinguishability of fundamental particles are also discussed.

Intermediate

Impossible Machines in Quantum Mechanics

In this course, we talk about four quantum machines that are impossible to build. We give a simple proof to one of them and show how they other three can be proven by induction.

Uncertainty Relations

In this course, we give a more in-depth account of the uncertainty relations by discussing different types of uncertainties and how these uncertainty relations are related.

Introduction to Quantum Computing

In this course, we will introduce the basic notions of quantum computing. Single-qubit and two-qubit gates are studied in details. We will also discuss Deutsch algorithm and teleportation protocol.
