Entropic Inequalities and Marginal Problems
Tobias Fritz, Rafael Chaves
A marginal problem asks whether a given family of marginal distributions for some set of random variables arises from some joint distribution of these variables. Here we point out…
Robust multipartite quantum correlations without complex encodings
Rafael Chaves, Leandro Aolita, Antonio Acín
One of the main challenges for the manipulation and storage of multipartite entanglement is its fragility under noise. We present a simple recipe for the systematic enhancement of…
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…
Feasibility of loophole-free nonlocality tests with a single photon
Rafael Chaves, Jonatan Bohr Brask
Recently much interest has been directed towards designing setups that achieve realistic loss thresholds for decisive tests of local realism, in particular in the optical regime. W…
