<p dir="ltr">This thesis explores the intersection of quantum interference, entanglement, and quantum
algorithms in the context of chemical reactions. The initial exploration delves into the
constructive quantum interference in the photoassociation reaction of a 87Rb Bose Einstein
condensate (BEC), where a coherent superposition of multiple bare spin states is achieved
and it’s impact on photo-association (PA) was studied. Employing a quantum processor, the
study illustrates that interferences can function as a resource for coherent control in photochemical
reactions, presenting a universally applicable framework relevant to a spectrum of
ultracold chemical reactions. The subsequent inquiry scrutinizes the entanglement dynamics
between the spin and momentum degrees of freedom in an optically confined BEC of 87Rb
atoms, induced by Raman and RF fields. Significantly, this study unveils substantial spin momentum
entanglement under specific experimental conditions, indicating potential applications
in the realm of quantum information processing. Finally, the third study advances a
quantum algorithm for the computation of scattering matrix elements in chemical reactions,
adeptly navigating the complexities of quantum interactions. This algorithm, rooted in the
time-dependent method and Möller operator formulation, is applied to scenarios such as 1D
semi-infinite square well potentials and co-linear hydrogen exchange reactions, showcasing
its potential to enhance our comprehension of intricate quantum interactions within chemical
systems.</p>
