dc.description.abstract |
The currently ongoing dawn of quantum technologies, such as quantum information
and quantum metrology, leaves some to speak of a quantum revolution.
The development of the required physical "hardware" goes hand-in-hand with
quantum state engineering, i.e., the design of quantum protocols that prepare
the quantum states required as resources for these technologies. Concentrated
efforts have produced a plethora of potential schemes for this purpose. However,
trying to improve on and optimise these is vital and thus a main drive of
the field. The topic of this thesis is precisely that, the search for novel generation
schemes that are potentially easier, more high yield or more "quantum".
Common issues within this topic are the susceptibility of these states to fall
victim to decoherence, and the probabilistic nature of certain techniques. The
"hardware" considered here are cavity quantum electrodynamics systems, i.e.,
optical cavities in which atom-light interactions are enhanced. The parameter
regimes made accessible by state-of-the-art optical cavities open up new roads
for investigations when it comes to protocols, and a variety of them are therefore
considered here. A central aspect of this thesis is also further inspection of
the recently experimentally-implemented Dicke model in integer-spin atoms.
Even though it is one of the fundamental models of quantum optics, it does
not arise naturally and can thus only be studied in engineered systems like
this one. The quantum states we target to engineer within this thesis are,
firstly, light pulses containing Fock states, 0N-states, binomial-code-states,
and Greenberger-Horne-Zeilinger states. Additionally, we also aim to produce
two-mode (or two-colour) light with quantum-correlated photon statistics. Secondly,
in ensembles of atoms, we propose to create entangled spin states such
as Schrödinger’s cat states and Dicke states. Among these, the states of light would mainly find application and lead to further developments in quantum
information, while the atomic states would find a use in quantum metrology. |
