Geometric Phase as the Key to Interference in Phase Space : Integral Representations for States and Matrix Elements
Mayukh N. Khan, S. Chaturvedi, N. Mukunda +1
We apply geometric phase ideas to coherent states to shed light on interference phenomenon in the phase space description of continuous variable Cartesian quantum systems. In contr…
Divergence-free approach for obtaining decompositions of quantum-optical processes
K. K. Sabapathy, J. S. Ivan, R. García-Patrón +1
Operator-sum representations of quantum channels can be obtained by applying the channel to one subsystem of a maximally entangled state and deploying the channel-state isomorphism…
Strong subadditivity for log-determinant of covariance matrices and its applications
Gerardo Adesso, R. Simon
We prove that the log-determinant of the covariance matrix obeys the strong subadditivity inequality for arbitrary tripartite states of multimode continuous variable quantum system…
Classical Light Beams and Geometric Phases
N. Mukunda, S. Chaturvedi, R. Simon
We present a study of geometric phases in classical wave and polarisation optics using the basic mathematical framework of quantum mechanics. Important physical situations taken fr…
Quantum discord for two-qubit -states: A comprehensive approach inspired by classical polarization optics
Krishna Kumar Sabapathy, R. Simon
Classical correlation and quantum discord are computed for two-qubit -states. Our approach, which is inspired by the methods of classical polarization optics, is geometric in th…
Relative volume of separable bipartite states
Rajeev Singh, Ravi Kunjwal, R. Simon
Every choice of an orthonormal frame in the d-dimensional Hilbert space of a system corresponds to one set of all mutually commuting density matrices or, equivalently, a classical…
