## Superposition

Superposition is a fundamental principle in quantum mechanics that describes the ability of quantum systems to exist in multiple states simultaneously until they are measured. In other words, a quantum system can be in a combination, or superposition, of different states at the same time. This concept contrasts with classical physics, where an object typically… Continue reading Superposition

## The Mathematics of Quantum Mechanics (Concepts of Physics)

In this book we expose the mathematics for quantum mechanics. The main topics are: vectors, ket and bra space, properties and operations, product for a scalar, internal product between ket and bra, norm and Schwarz inequality, orthogonality, operators and their operations, operator acting on kets as a measure of an observable for a physical state,… Continue reading The Mathematics of Quantum Mechanics (Concepts of Physics)
