Lorentz covariant reduced - density - operator theory for relativistic quantum information processing
In this paper, we derived Lorentz covariant quantum Liouville equation for the density operator which describes the relativistic quantum information processing from Tomonaga-Schwinger equation and an exact formal solution for the reduced-density-operator is obtained using the projector operator technique and the functional calculus. When all the members of the family of the hypersurfaces become...

متن کاملTime-convolutionless reduced-density-operator theory of a noisy quantum channel: a two-bit quantum gate for quantum information processing
An exact reduced-density-operator for the output quantum states in timeconvolutionless form was derived by solving the quantum Liouville equation which governs the dynamics of a noisy quantum channel by using a projection operator method and both advanced and retarded propagators in time. The formalism developed in this work is general enough to model a noisy quantum channel provided specific f...
متن کاملQuantum Information Processing Theory
Definition Quantum information processing theory is an alternative mathematical approach for generating theories of how an observer processes information. Typically, quantum information processing models are derived from the axiomatic principles of quantum probability theory. This probability theory may be viewed as a generalization of classic probability. Quantum information processing models ...
متن کاملOperator structures in quantum information theory
Physicists have long recognized that the appropriate framework for quantum theory is that of a Hilbert space H and in the simplest case the algebra of observables is contained in B(H). This motivated von Neumann to develop the more general framework of operator algebras and, in particular C∗algebras and W ∗algebras (with the latter also known as von Neumann algebras). In the 1970’s these were u...
