0.5 - Quantum States

The lecture slides are available here Download here.

Explore the world of quantum states in our video presentation, where we delve into two simple examples to grasp their essence: a quantum particle confined to specific positions on a line and a single-particle spin system. Follow along as we introduce the concept of particle states represented by complex column vectors, explaining how they relate to physical locations. Understand the intriguing idea of quantum superposition, where particles exist in a blend of basic states with complex amplitudes. We also break down the role of complex numbers in determining probabilities in quantum states. Moving on, we examine spin systems through the lens of the Stern-Gerlach experiment, exploring how particles behave in magnetic fields. By the end of the presentation, you'll have a solid understanding of quantum states and their significance in quantum computing.
