On the quantum polarization and entanglement of superposition of two two-mode coherent states
Joao Batista Rosa Silva, Rubens Viana Ramos
This work discuss the entanglement and quantum polarization of superpositions of two-mode coherent states. We use the concurrence to measure their entanglements and the quantum Sto…

Implementation of non-local XOR function for coherent-state qubit
Joao Batista Rosa Silva, Rubens Viana Ramos
This work describes how to implement a non-local xor function for coherent-state qubit using only linear optics. The setup proposed does not use gates based on teleportation and it…

Implementations of quantum and classical gates with linear optical devices and photon number quantum non-demolition measurement for polarization encoded qubits
Joao Batista Rosa Silva, Rubens Viana Ramos
Aiming the construction of quantum computers and quantum communication systems based on optical devices, in this work we present possible implementations of quantum and classical C…
