No-splitting Theorem: Principles of Quantum Information
In the context of quantum information there arise a number of interesting questions regarding the domains of operations which are feasible in classical context to be applicable in quantum information domain or not. The criterion of feasibility and non feasibility of various physical processes in quantum regime creates a set of impossible operations[1-6]. This may be probably due to the linear s...
متن کاملQuantum information splitting using a pair of GHZ states
We describe a protocol for quantum information splitting (QIS) of a restricted class of three-qubit states among three parties Alice, Bob and Charlie, using a pair of GHZ states as the quantum channel. There are two different forms of this three-qubit state that is used for QIS depending on the distribution of the particles among the three parties. There is also a special type of four-qubit sta...
متن کاملQuantum Teleportation and Beam Splitting
Following the previous paper in which quantum teleportation is rigorously discussed with coherent entangled states given by beam splittings, we further discuss two types of models, perfect teleportation model and non-perfect teleportation model, in general scheme. Then the difference among several models, i.e., the perfect models and the non-perfect models, is studied. Our teleportation models ...
متن کاملBrane Splitting via Quantum Tunneling
We study the two-centred AdS7×S solution of eleven-dimensional supergravity using the Euclidean path-integral approach, and find that it can be interpreted as an instanton, signalling the splitting of the throat of the M5 brane. The instanton is interpreted as indicating a coherent superposition of the quantum states corresponding to classically distinct solutions. We discuss the potential impl...
متن کاملLarge Vacuum Rabi Splitting in a Single Nitride-Based Quantum WellMicrocavity
Here, we report a theoretical detailed study of Vacuum Rabi Splitting (VRS) in the system of Nitride Single Quantum Well (SQW) within a semiconductor microcavity. Distributed Bragg Reflectors (DBRs) containing ZnTe/ZnSe multilayers including GaAs microcavity and ( SQW at the center of microcavity, has been considered. Upper and lower exciton-polariton branches obtaine...
