General theory of measurement with two copies of a quantum state
(American Physical Society, 2009-07)
We analyze the results of the most general measurement on two copies of a quantum state. We show that by using two copies of a quantum state it is possible to achieve an exponential improvement with respect to known methods ...
Simulação de algoritmos quânticos considerando a teoria quântica modal em Haskell
(Universidade Federal de Santa MariaBrasilCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Ciência da ComputaçãoCentro de Tecnologia, 2014-08-29)
The development of quantum algorithms faces some difficulties such as the lack of a
general-purpose quantum computer, a language or a specific formalism, or high consumption
of computational resources when it is simulation ...
Enhanced multiqubit phase estimation in noisy environments by local encoding

Parameters analysis of QIEA-R in convergence quality
(Institute of Electrical and Electronics Engineers Inc., 2017)
QIEA-R (Quantum Inspired Evolutionary Algorithm with Real Codification) was proposed for solving numerical problems obtaining better results when compared with traditional EAs, DE and PSO algorithms. It is inspired on the ...
Multiple classical limits in relativistic and nonrelativistic quantum mechanics
(AMER INST PHYSICS, 2009)
The existence of a classical limit describing the interacting particles in a second-quantized theory of identical particles with bosonic symmetry is proved. This limit exists in addition to the previously established ...
Entropic relations for retrodicted quantum measurements
(American Physical Society, 2018-01)
Given an arbitrary measurement over a system of interest, the outcome of a posterior measurement can be used for improving the statistical estimation of the system state after the former measurement. Here, we realize an ...
