Measuring the Quantum Polarization State of Lightents using dual-polarization balanced homodyne detection is shown to be . with respect to the statistics of the SU(2) Stokes operators on the Poincaré sphere. Complete reconstruction of the polarization sector of the density matrix of a partially polarized optical field can be achieved while randomi

Group Covariant Signals in Quantum Information Theoryals.” We show by applying this condition that many signals, such as arbitrary binary signals, PPM, FSK, and PSK coherent-state signals, equidistant codes, and binary linear codes, are all group covariant.

Entanglement of Formationthe entanglement of formation, as well as a related quantity called the tangle. The tangle can be used to express a simple law of entanglement, limiting the extent to which a single qubit may be simultaneously entangled with each of two other qubits.

Optimal Signal-to-Quantum Noise Ratio in Squeezed Displaced Number States . has the value 4. .(. .+1), attainable by the squeezed coherent vacuum. The question arises as to what ρ is attainable when the vacuum is imperfect, and there are . photons present. We show that in such a situation the attainable signal-to-quantum noise ratio ρ is reduced by a factor (2.+1)..

On Quantum Channel Capacity for Squeezed StatesThis paper presents the classical capacities of quantum Gaussian channels using squeezed states. The calculation is based on a general formula for the entropy of quantum Gaussian state.
