Quantum holography and multiparticle entanglement using ground-state coherences
G. S. Agarwal, P. Lougovski, H. Walther
A method of storing and retrieving quantum states of radiation fields using the ground-state coherences is discussed. We demonstrate the generation of multiparticle entangled state…
Microscopic Origin of Spatial Coherence and Wolf Shifts
Girish S. Agarwal
We show that the vacuum of electromagnetic field has intrinsic partial spatial coherence in frequency domain which effectively extends over regions of the order of wavelength .…
Slow Light in Doppler Broadened Two level Systems
G. S. Agarwal, Tarak Nath Dey
We show that the propagation of light in a Doppler broadened medium can be slowed down considerably eventhough such medium exhibits very flat dispersion. The slowing down is achiev…
From Storage and Retrieval of Pulses to Adiabatons
Tarak Nath Dey, G. S. Agarwal
We investigate whether it is possible to store and retrieve the intense probe pulse from a -type homogeneous medium of cold atoms. Through numerical simulations we show that it…
Arbitrary qubit rotation through nonadiabatic evolution
Asoka Biswas, G. S. Agarwal
We show how one can perform arbitrary rotation of any qubit, using delayed laser pulses through nonadiabatic evolution, i.e., via transitions among the adiabatic states. We use a d…
Giant Radiative Interactions Among Distant Atoms
G. S. Agarwal, S. Dutta Gupta
We examine the feasibility of enhancing the fundamental radiative interactions between distant atoms. We present general arguments for producing enhancement. In particular, we show…
