Generalized tomographic maps and star-product formalism
M. Asorey, P. Facchi, V. I. Man'ko +3
We elaborate on the notion of generalized tomograms, both in the classical and quantum domains. We construct a scheme of star-products of thick tomographic symbols and obtain in ex…
Derivation of the TCP Theorem using Action Principles
Mark Selover, E. C. G. Sudarshan
We present a new derivation of the proof for the TCP/CPT Theorem using the Dynamical Principle and Variation of Action methods first defined by Schwinger in 1951. This new proof wi…
Generalized quantum tomographic maps
M. Asorey, P. Facchi, V. I. Man'ko +3
Some non-linear generalizations of classical Radon tomography were recently introduced by M. Asorey et al [Phys. Rev. A 77, 042115 (2008), where the straight lines of the standard…
On the tomographic description of classical fields
A. Ibort, A. Lopez-Yela, V. I. Man'ko +4
After a general description of the tomographic picture for classical systems, a tomographic description of free classical scalar fields is proposed both in a finite cavity and the…
Extremal Channels for a genaral Quantum system
Kuldeep Dixit, E. C. G. Sudarshan
Quantum channels can be mathematically represented as completely positive trace-preserving maps that act on a density matrix. A general quantum channel can be written as a convex s…
The role of preparation in quantum process tomography
Kavan Modi, E. C. G. Sudarshan
In a recent letter one of us pointed out how differences in preparation procedures for quantum experiments can lead to non-trivial differences in the results of the experiment. The…
