...h are manipulatable by the existing technologies ... PhD Thesis in Gaussian and non-Gaussian resources in ... ... . So far, most of the important quantum information experiments are done with such states, including bright Gaussian light and weak Gaussian light. Our approach to quantum Gaussian states is based on the characteristic function of the state which closely parallels classical probability [11], [12], and is perhaps the simplest and most ... I know what is a Gaussian function and Gaussian distribution, but I don't know how to respond to other when they ask me to provide the definition of a Gaussian state.

Thank you. quantum-mechanics quantum-information quantum-optics quantum-states Quantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. So far, most of the important quantum information experiments are done with such states, including bright Gaussian light and weak Gaussian light. Advanced quantum technologies require scalable and controllable quantum resources1,2. Gaussian states of multimode light, such as squeezed states and cluster states, are scalable quantum systems3 ... It was realized later on that using continuous-variable quantum information carriers, instead of qubits, constitutes an extremely powerful alternative approach to quantum information processing. This review focuses on continuous-variable quantum information processes that rely on any combination of Gaussian states, Gaussian operations, and Gaussian measurements. Quantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. So far, most of the important quantum information experiments are done with such states, including bright Gaussian light and weak Gaussian light. Extending the existing results of quantum information with discrete quantum states to the case of continuous variable ... It is well known in the literature of quantum information, e.g., see [46] [47] [48], that Gaussian states can be decomposed in terms of standard operators defined using these creation and ... Quantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. So far, most of the important quantum information experiments are done with such states, including bright Gaussian light and weak Gaussian light. Extending the existing results of quantum information with discrete quantum states to the case of continuous variable ... The subject of this Thesis is quantum information with fermions in the Gaussian setting. We study finite-dimensional fermionic Gaussian quantum states and channels. We show that Gaussian states are extremal with respect to a certain class of functionals among all states with the same second moments. This result can be used to bound certain entanglement-like quantities as well as to compute the ... Gaussian States In Quantum Information è un libro di Ferraro A. (Curatore), Olivares S.

Preparationofquantumstates. −The quantum states represent the essential ingredient of each protocol. There are two important distinct classes: Gaussian and non-Gaussian states. The Gaussian states are described by a Gaussian characteristic function, all other states are non-Gaussian. Both the A quite broad set of issues are covered, ranging from elementary concepts to current research topics, and from fundamental concepts to applications. A special emphasis has been given to the phase space analysis of quantum dynamics and to the role of Gaussian states in continuous variable quantum information. Gaussian States in Quantum Information. Collana: Napoli series on Physics and Astrophysics. Categoria: FISICA, fisica. €20.00 ... In physics and computer science, quantum information is the information of the state of a quantum system.It is the basic entity of study in quantum information theory, and can be manipulated using quantum information processing techniques. Quantum information refers to both the technical definition in terms of Von Neumann entropy and the general computational term.
