A model for quantum BER estimation in polarization encoded quantum key distribution
systems is presented. Both TDM and WDM based polarization control schemes are …

In this paper we present results from the study of optical signal amplification using Raman
assisted fiber optical parametric amplifier with considerable benefits for S-band …

We present a two-state practical quantum bit commitment protocol, the security of which is
based on the current technological limitations, namely the nonexistence of either stable long …

We investigate the effects of waveguide loss and nonlinearities on the generation of
polarization entangled photon-pairs through spontaneous four-wave mixing (FWM) in X (3) …

The impact of fiber absorption on the generation rate of quantum-correlated photon pairs
through spontaneous four-wave mixing in optical fibers is studied theoretically. We quantify …

We reconstruct the photon statistics of a single-photon source based on the stimulated four-
wave mixing (FWM) process. We find that the statistics of the source goes from thermal, at a …

The second-order coherence function for idler photons generated through stimulated four-
wave mixing (FWM) is theoretically derived, considering both spontaneous and stimulated …

A single-photon source based on the stimulated four-wave mixing (SFWM) process in optical
fibers is presented. At the output of the source, the state of polarization (SOP) of the photons …

In this paper, nonlinear nature of three different optical fibers: Corning SMF-28 ultra optical
fiber, Draka enhanced single-mode optical fiber and highly nonlinear fiber has been studied …

Quantum laws can be used to implement secure communication channels; this has been
named quantum cryptography. In quantum cryptography the security does not depend of …
