Using Disentangled States and Algorithmic Information Theory to Construct a Not P Problem
Rubens Viana Ramos
In this work, are used Chaitin number Omega and the fact that the general decomposition of an N-way disentangled state is an irreducible sentence whose number of coefficients grows…
The Relation between Disentangled States and Algorithmic Information Theory
Rubens Viana Ramos
In this short communication it is proposed the general form of a n-qubit disentangled state as a irreducible sentence, in the sense explained by the algorithmic information theory,…
Simple setups for quantum games in optical networks
Rubens Viana Ramos, Paulo Benicio Melo de Sousa
In this work, we propose two optical setups for two-players, non-zero and zero sum, quantum games in optical networks using light polarization of single-photon pulses, single-photo…
Hybrid Parallel Quantum Key Distribution Protocol
Fabio Alencar Mendonca, Rubens Viana Ramos
The practical realizations of BB84 quantum key distribution protocol using single-photon or weak coherent states have normally presented low efficiency, in the meaning that most bi…
Linear optical setups for active and passive quantum error correction in polarization encoded qubits
Jose Claudio do Nascimento, Fabio Alencar Mendonca, Rubens Viana Ramos
In this work, we present active and passive linear optical setups for error correction in quantum communication systems that employ polarization of single-photon and mesoscopic coh…
Contract Signature Using Quantum Information
Paulo Benicio Melo de Sousa, Rubens Viana Ramos
This paper describes how to perform contract signature in a fair way using quantum information. The protocol proposed permits two partners, users of a communication network, to per…
