Quantum Computing – Theory and Practice: The Qubit and Quantum computation

This is part of the short course ‘Quantum Computing – Theory and Practice’, http://talks.cam.ac.uk/show/index/86491

This course covers fundamental theoretical concepts of quantum computation and quantum information will be covered. In addition, hands-on experimentation of quantum algorithms will be demonstrated on actual quantum devices. Special consideration will be given to realization of limitations of current, non-fault tolerant quantum systems, as well as means to mitigate them when possible.

Specifically, lecture 2 covers:
a. The qubit – Bloch sphere, basis state, superposition, entanglement (Bell state example)
b. Quantum computation – single qubit and controlled operations, universality, quantum circuits (super-dense coding and teleporation examples)
c. Hands-on experimentation of quantum algorithms on a quantum system via the IBM (Quantum Experience http://research.ibm.com/ibm-q/)

There will be a 15 minute break in the middle of the lecture.

It is useful for students to have a laptop/tablet (or even a smartphone) for some of the more practical examples, but this is not necessary. Those without computer access can follow a demo shown by the instructor.
