Exploring the foundation of quantum information in quantum optics
Abstract
Quantum information is promising in solving certain computational problems and information
security. The power of its speed up and privacy is based on one of the most
tested physical theory: quantum mechanics. Many of the promises of quantum information
has already been demonstrated in different implementations, which could also be viewed
as witness of quantum mechanics. As we progress further in quantum information, we find
that some of the aspects of quantum mechanics could be tested in a novel way. Performing
those tests may lead to new physical theory or at least reinforce our belief of the accuracy
of quantum mechanics. In this thesis, I report a few different approaches in testing the
foundation of quantum mechanics using results obtained from quantum optics. While developing
such test, quantum state tomography is heavily used to characterize our system.
I also report a simplified way of performing quantum state tomography for quantum state
that is close to pure state.
