Entanglement is a physical phenomenon described by the quantum theory. When the system is composed by two or more entangled particles, their quantum state must be understood as a whole, not as independent quantum states, ...

The common threads of my work in the Ph.D. was entanglement sources and the work and the works that served as an experimental basis are [20, 47]. Here, prove partially entangled state (PES) in quantum information protocols ...

Over two decades, it has been discussing whether the entanglement can bring advan- tages to the capacity of classical communication over a quantum channel. Today it is already known that some improvement in the capacity ...

Em considerando-se dois subsistemas A e B com espaço de estados HA e HB e com o espaço do sistema total ( A+B ) associado ao produto tensorial HA ? HB, alguns vetores desse sistema total podem ser decompostos em um produto ...

This thesis consists of three studies in the context of cavity quantum electrodynam- ics. Firstly, we investigate the quantum-to-classical transition of a dissipative cavity .eld by measuring the correlations between two ...
