Entanglement and Applications of Pure Fourpartite of Qubit States
David Sena Oliveira, Rubens Viana Ramos
In this work we study the entanglement of pure fourpartite of qubit states. The analysis is realized through the comparison between two different entanglement measures: the Groveri…
Asymptotic Quantum Search and a Quantum Algorithm for Calculation of a Lower Bound of the Probability of Finding a Diophantine Equation That Accepts Integer Solutions
R. V. Ramos, J. L. de Oliveira
Several mathematical problems can be modeled as a search in a database. An example is the problem of finding the minimum of a function. Quantum algorithms for solving this problem…
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…
Multiplayer Quantum Games and its Application as Access Controller in Architecture of Quantum Computers
Paulo Benicio, Melo de Sousa, Rubens Viana Ramos
One of the basics tasks in computer systems is the control of access of resources. Basically, there is a finite amount of resources that can be, for example, the CPU, memory or I/O…
Quantum Zero-Knowledge Protocol Using Quantum Bit Commitment without Quantum Memory
Rubens Viana Ramos, Jose Claudio do Nascimento
Zero-knowledge proof system is an important protocol that can be used as a basic block for construction of other more complex cryptographic protocols. Quantum zero-knowledge protoc…
Quantum bit commitment protocol without quantum memory
Rubens Viana Ramos, Fabio Alencar Mendonca
Quantum protocols for bit commitment have been proposed and it is largely accepted that unconditionally secure quantum bit commitment is not possible; however, it can be more secur…
