Abstract: This paper deals with the modeling of an optimum quantum receiver for pulse amplitude modulator (PAM) communication systems. The information bearing sequence $$\{I_k\}_{k=0}^{N-1}$${Ik}k=0N-1 is estimated using the maximum likelihood (ML) method. The ML method is… read more here.

Abstract: We experimentally demonstrate a quantum receiver based on Kennedy scheme for discrimination between two phase-modulated weak coherent states. The receiver is assembled entirely from the standard fiber-optic elements and operates at the conventional telecom wavelength… read more here.
