Understanding of collective atom phase control in modified photon echoes for a near perfect, storage time extended quantum memory
Rahmatullah, B. S. Ham
A near perfect, storage time-extended photon echo-based quantum memory protocol has been analyzed by solving the Maxwell-Bloch equations for a backward scheme in a three-level syst…
Gaussian pulse-induced imperfect rephasing in coherent transients
B. S. Ham
A double-rephasing photon-echo (DRPE) scheme inherently satisfies no-population inversion condition for quantum memory applications, while the resultant absorptive coherence prohib…
Coherent control of collective atom phase for ultralong, inversion-free photon echoes
B. S. Ham
To overcome fundamental limitations of the πoptical pulse-induced population inversion and optical decay-caused short storage time in conventional photon echoes, a coherent control…
Collective atom phase-controlled noise-free photon echoes using double rephasing and optical locking
B. S. Ham
Using collective atom phase control a population inversion-free photon echo scheme has been studied for quantum memory applications. For the inversion-free photon echoes a double r…
Phase Locked Photon Echoes for Near-Perfect Retrieval Efficiency and Extended Storage Time
B. S. Ham, J. Hahn
Quantum storage of light in a collective ensemble of atoms plays an important role in quantum information processing. Consisting of a quantum repeater together with quantum entangl…
Quantum control and manipulations with stationary three-color lights
S. A. Moiseev, B. S. Ham
A dynamic quantum control of three-color lights in an optically dense medium is presented. We discuss how effectively to stop traveling three-color light pulses in the medium by us…
Quantum manipulation of two-color stationary light: Quantum wavelength conversion
S. A. Moiseev, B. S. Ham
We present a quantum manipulation of a traveling light pulse using double atomic coherence for two-color stationary light and quantum frequency conversion. The quantum frequency co…
Perspectives for quantum state engineering via high non-linearity in a double-EIT regime
M. Paternostro, M. S. Kim, B. S. Ham
We analyse the possibilities for quantum state engineering offered by a model for Kerr-type non-linearity enhanced by electromagnetically induced transparency (EIT), which was rece…
