Abstract

This doctoral thesis focuses on the issue of phase matching in a quantum memory operating on a cold cloud of $^{87}$Rb atoms, where non-resonant Raman scattering is used as an interface between light and atoms. Experimental results and considerations for controlling the memory readout process by using the Zeeman effect, ac-Stark effect, controlling the laser beam geometry, or using an optical ring cavity are presented.
