Quantum information theory is a new branch of physics and mathematics that studies the properties of quantum systems from an information-theoretic point of view.
It has been developed in the last few decades and has already produced some remarkable results, such as Shor's algorithm for integer factorisation or Grover's algorithm for database searching.
In this talk we will present some basic concepts and results in this field: qubits, entanglement, teleportation, no-cloning theorem, etc.
