Quantum Aberrations: Entangling Photons with Zernike Polynomials
Hakob Avetisyan, Gor Nikoghosyan
We introduce Zernike polynomials as a novel degree of freedom for encoding quantum information in the spatial structure of photons. Building on their orthogonality and completeness…
Photon-number selective group delay in cavity induced transparency
Gor Nikoghosyan, Michael Fleischhauer
We show that the group velocity of a probe pulse in an ensemble of -type atoms driven by a quantized cavity mode depends on the quantum state of the input probe pulse. In the st…
Irreversible photon transfer in an ensemble of -type atoms and photon diode
Gor Nikoghosyan, Michael Fleischhauer
We show that a pair of quantized cavity modes interacting with a spectrally broadened ensemble of Lambda-type atoms is analogous to an ensemble of two level systems coupled to a bo…
Frequency matching in light storage spectroscopy of atomic Raman transitions
Leon Karpa, Gor Nikoghosyan, Frank Vewinger +2
We investigate the storage of light in an atomic sample with a lambda-type coupling scheme driven by optical fields at variable two-photon detuning. In the presence of electromagne…
Stationary light in cold atomic gases
Gor Nikoghosyan, Michael Fleischhauer
We discuss stationary light created by a pair of counter-propagating control fields in Lambda-type atomic gases with electromagnetically induced transparency for the case of neglig…
Influence of relaxation on propagation, storage and retrieving of light pulses in electromagnetically induced transparency medium
Gor Nikoghosyan, Gayane Grigoryan
By solving the self-consistent system of Maxwell and density matrix equations to the first order with respect to nonadiabaticity, we obtain an analytical solution for the probe pul…
Storage and perpendicular retrieving of two-dimensional pulses in electromagnetically induced transparency media
Gor Nikoghosyan
Propagation of two dimensional pulses in electromagnetically induced tranparency media in the case of perpendicular storing and retrieving pulses has been analyzed. It has been sho…
