Purified discord and multipartite entanglement
Eric G. Brown, Eric J. Webster, Eduardo Martin-Martinez +1
We study bipartite quantum discord as a manifestation of a multipartite entanglement structure in the tripartite purified system. In particular, we find that bipartite quantum disc…
Detectors for probing relativistic quantum physics beyond perturbation theory
Eric G. Brown, Eduardo Martin-Martinez, Nicolas C. Menicucci +1
We develop a general formalism for a non-perturbative treatment of harmonic-oscillator particle detectors in relativistic quantum field theory using continuous-variables techniques…
Processing quantum information with relativistic motion of atoms
Eduardo Martin-Martinez, David Aasen, Achim Kempf
We show that particle detectors, such as 2-level atoms, in non-inertial motion (or in gravitational fields) could be used to build quantum gates for the processing of quantum infor…
Localized detection of quantum entanglement through the event horizon
Andrzej Dragan, Jason Doukas, Eduardo Martin-Martinez
We present a completely localized solution to the problem of entanglement degradation in non-inertial frames. A two mode squeezed state is considered from the viewpoint of two obse…
Wavepacket detection with the Unruh-DeWitt model
Eduardo Martin-Martinez, Miguel Montero, Marco del Rey
In this paper we deal with several issues regarding the localization properties of the Unruh-DeWitt (UdW) detector model. Since its original formulation as a pointlike detector, th…
Fundamental quantum optics experiments conceivable with satellites -- reaching relativistic distances and velocities
David Rideout, Thomas Jennewein, Giovanni Amelino-Camelia +14
Physical theories are developed to describe phenomena in particular regimes, and generally are valid only within a limited range of scales. For example, general relativity provides…
Vanishing Geometric Discord in Non-Inertial Frames
Eric G. Brown, Kyle Cormier, Eduardo Martin-Martinez +1
We show that quantum field correlations in non-inertial frames are not as persistent as previously thought. We perform a simple calculation showing that the geometric discord, a me…
The fate of non-trivial entanglement under gravitational collapse
Eduardo Martin-Martinez, Luis J. Garay, Juan Leon
We analyse the evolution of the entanglement of a non-trivial initial quantum field state (which, for simplicity, has been taken to be a bipartite state made out of vacuum and the…
Non-monotonic entanglement of physical EM field states in non-inertial frames
Miguel Montero, Marco del Rey, Eduardo Martin-Martinez
We develop a general technique to analyse the quantum effects of acceleration on realistic spatially-localised electromagnetic field states entangled in the polarization degree of…
Fundamental limitations to information transfer in accelerated frames
Eduardo Martin-Martinez, Dominic Hosler, Miguel Montero
We study communication between an inertial observer and one of two causally-disconnected counter accelerating observers. We will restrict the quantum channel considering inertial-t…
Localised projective measurement of a relativistic quantum field in non-inertial frames
Andrzej Dragan, Jason Doukas, Eduardo Martin-Martinez +1
We propose a scheme to study the effect of motion on measurements of a quantum field carried out by a finite-size detector. We introduce a model of projective detection of a locali…
Extracting past-future vacuum correlations using circuit QED
Carlos Sabin, Borja Peropadre, Marco del Rey +1
We propose a realistic circuit QED experiment to test the extraction of past-future vacuum entanglement to a pair of superconducting qubits. The qubit P interacts with the quantum…
