Coherence generation and population transfer by stimulated Raman adiabatic passage and π pulse in a four-level ladder system
TLDR
A new scheme for achieving the complete population transfer and the optimal coherence generation between the ground state and the Rydberg state in a four-level ladder system by combining the STirAP or fractional STIRAP technique and the π pulse technique is proposed.Abstract:
We propose a new scheme for achieving the complete population transfer and the optimal coherence generation between the ground state and the Rydberg state in a four-level ladder system by combining the STIRAP or fractional STIRAP technique and the π pulse technique. We consider, in particular, two different situations where spontaneous emission from the two highest states are neglected or not. Our numerical calculations show that the time width and the delay time of the π pulse are two critical parameters for attaining the maximal population transfer and coherence generation in this scheme.read more

Quantum information with Rydberg atoms
TL;DR: Rydberg atoms with principal quantum number $n⪢1$ have exaggerated atomic properties including dipole-dipole interactions that scale as ${n}^{4}$ and radiative lifetimes that scale at least{n}−3}$ as mentioned in this paper, and it was proposed a decade ago to implement quantum gates between neutral atom qubits.

Observation of electromagnetically induced transparency
TL;DR: The first demonstration of a technique by which an optically thick medium may be rendered transparent is reported, which results from a destructive interference of two dressed states created by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.

Coherent population transfer among quantum states of atoms and molecules
TL;DR: In this paper, the authors discuss the technique of stimulated Raman adiabatic passage (STIRAP), a method of using partially overlapping pulses (from pump and Stokes lasers) to produce complete population transfer between two quantum states of an atom or molecule.

Coherent trapping of atomic populations.
TL;DR: A form of coherent trapping that occurs when multiple resonant laser beams are used to couple the various ground states to a common upper level is described, which prevents the extraction of the entire population.
