Abstract.
I will present a simple discussion on the mathematical formalism of Quantum Operations. These are key tools used to describe the dynamics of open quantum systems and are rather different than traditional methods.
No systems are perfectly closed and especially not Quantum Computers. The Quantum Operations formalism simultaneously addresses a wide range of physical scenarios. It can describe closed systems weakly coupled to their environment, systems which are strongly coupled to their environment and closed systems that open suddenly when subjected to measurement. We will see that the discrete nature of this formalism gives much insight into the world of Quantum Computation and Quantum Information. I will also discuss the advantages and limitations of this formalism approach.
Everyone welcome!
