The Landau-Feynman transiently open quantum system: entanglement and density operators
Alain Deville, Yannick Deville
Users of quantum mechanics, both in physics and in the field of quantum information, are familiar with the concept of a statistical mixture as introduced by von Neumann, and with t…
Multi-stage tomography based on eigenanalysis for high-dimensional dense unitary processes in gate-based quantum computers
Yannick Deville, Alain Deville
Quantum Process Tomography (QPT) methods aim at identifying, i.e. estimating, a quantum process. QPT is a major quantum information processing tool, since it especially allows one…
Solving the Zeh problem about the density operator with higher-order statistics
Alain Deville, Yannick Deville
Since a 1932 work from von Neumann, it is generally considered that if two statistical mixtures are represented by the same density operator \r{ho}, they should in fact be consider…
Beyond the density operator and Tr(ρA): Exploiting the higher-order statistics of random-coefficient pure states for quantum information processing
Yannick Deville, Alain Deville
Two types of states are widely used in quantum mechanics, namely (deterministic-coefficient) pure states and statistical mixtures. A density operator can be associated with each of…
Random-coefficient pure states, the density operator formalism and the Zeh problem
Alain Deville, Yannick Deville
Quantum electronics is significantly involved in the development of the field of quantum information processing. In this domain, the growth of Blind Quantum Source Separation and B…
Statistical intrusion detection and eavesdropping in quantum channels with coupling: Multiple-preparation and single-preparation methods
Yannick Deville, Alain Deville, Ali Mansour +2
Classical, i.e. non-quantum, communications include configurations with multiple-input multiple-output (MIMO) channels. Some associated signal processing tasks consider these chann…
