Lectures on Quantum Computation by David Deutsch

• Lecture I - The QuBit
  Introducing quantum theory, the quantum theory of computation, physical systems, observations, and the simplest quantum physical system, the qubit.
  
  
• Lecture II - Interference
  Performing and analysing a single-photon interference experiment.
  


• Lecture III - Measurement
  How to analyse pairs of interacting quantum systems.
  


• Lecture IV - The Schroedinger Picture
  Introducing the Schroedinger Picture, density matrices, state vectors, pure states and the Schroedinger equation.
  


• Lecture V - A Quantum Algorithm
  The Deutsch Algorithm and how it works.
  


• Lecture V - Grover's Search Algorithm
  How to use quantum computation to search through N possibilities in a time proportional to the square root of N.
