Toward a full reconstruction of density matrix by on/off measurements / G. Brida, M. Genovese, M. Gramegna, P. Traina, E. Predazzi, S. Olivares, M. Paris. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 7:suppl.(2009), pp. 27-32.
Abstract:
The knowledge of density matrix is fundamental for several applications, ranging from
quantum information to the foundations of quantum mechanics and quantum optics.
Nevertheless, quantum tomography based on homodyne detection is a rather complicated
technique when applied to short pulses in photocounting regime. In this paper, we present
an experimental work addressed to test an innovative scheme for a full reconstruction
of the density matrix by using on/off detection coupled to phase measurements respect to a local oscillator.
