- Abstract
- In this master thesis, a broad theoretical description is done of a novel
quantum state tomography protocol called KRAKEN. This protocol is
meant for the determination of the density matrix of an electronic state
created by absorption of XUV radiation in the vicinity of a Fano resonance. At first, a description of the KRAKEN protocol is provided.
Then, the theory of Fano resonances is discussed. After that, the physics
of two-photon transitions is presented. Finally, possible expansions of
KRAKEN using chirped or broadband IR probe pulses, are examined. - Popular Abstract
- In this master thesis, what is described is a way of performing measurements on electrons in a gas. When high-intensity light such as from a laser interacts with atoms electrons can be knocked off and ejected into the vacuum. This new method of performing measurements on the electrons is called KRAKEN and allows us to analyze more complex cases than with previous methods. In particular, cases where the electron and ion exhibit so-called entanglement requires something like KRAKEN. In fact, KRAKEN provides the first-ever theoretical protocol for quantifying entanglement in free electrons. The physics behind this process is explained and simulations are presented to demonstrate aspects and limitations of KRAKEN. Possible extensions of the... (More)

The physics behind this process is explained and simulations are presented to demonstrate aspects and limitations of KRAKEN. Possible extensions of the protocol are also discussed to hopefully make it much faster to perform. (Less)
