Geometry of the adiabatic theorem
A. C. Lobo, R. A. Ribeiro, P. R. Dieguez +1
We present a simple and pedagogical derivation of the quantum adiabatic theorem for two level systems (a single qubit) based on geometrical structures of quantum mechanics develope…
Tests of Bell inequality with arbitrarily low photodetection efficiency and homodyne measurements
Mateus Araújo, Marco Túlio Quintino, Daniel Cavalcanti +3
We show that hybrid local measurements combining homodyne measurements and photodetection provide violations of a Bell inequality with arbitrarily low photodetection efficiency. Th…
Mining Biclusters of Similar Values with Triadic Concept Analysis
Mehdi Kaytoue, Sergei O. Kuznetsov, Juraj Macko +2
Biclustering numerical data became a popular data-mining task in the beginning of 2000's, especially for analysing gene expression data. A bicluster reflects a strong association b…
Quantum computing with incoherent resources and quantum jumps
Marcelo F. Santos, Marcelo Terra Cunha, Rafael Chaves +1
Spontaneous emission and the inelastic scattering of photons are two natural processes usually associated with decoherence and the reduction in the capacity to process quantum info…
The Resource Theory of Quantum States Out of Thermal Equilibrium
Fernando G. S. L. Brandão, Michał Horodecki, Jonathan Oppenheim +2
The ideas of thermodynamics have proved fruitful in the setting of quantum information theory, in particular the notion that when the allowed transformations of a system are restri…
Continuous Monitoring of Dynamical Systems and Master Equations
L. F. Lopes Oliveira, R. Rossi, A. R. Bosco de Magalhaes +2
We illustrate the equivalence between the non-unitary evolution of an open quantum system governed by a Markovian master equation and a process of continuous measurements involving…
