As well known from a series of papers on precision measurements and detailed derivations of standard quantum limits, not taking into account decoherence results in an overestimate of the entanglement lifetime, and this is the case at hand. The entanglement lifetime is wrongly assumed by the ...
(Quantum Inf Process, QINP-D-18-00478R1, 2019) commented that a third party can obtain an authentication key from communicating parties by performing an entanglement swapping attack on the controlled mutual quantum entity authentication (CMQEA) protocol. In this response, we apply this attack to...
Many-body entanglement via ‘which-path’ information We propose a multi-particle ‘which-path’ gedanken experiment with a quantum detector. Contrary to conventional ‘which-path’ experiments, the detector maintains its quantum state during interactions with the particles. We show how such interaction...
Quantum correlations through event horizons: Fermionic versus bosonic entanglement We disclose the behavior of quantum and classical correlations among all the different spatial-temporal regions of a space-time with an event horizon, comp... E Martínmartínez,J León,E Martinmartinez,... - 《Physi...

Quantum PhysicsThe ability of parameter recently proposed by Sorensen et al. (Nature, 409, 63 (2001)) to characterize entanglement or inseparability is investigated for a system of two two-level atoms interacting with a single mode of radiation field. For comparison we employ the necessary and ...

We derive a rigorous bound on the form factor f+(0) in the form |f+(0)|≤[16/(mK-mπ)×(√mK+√mπ)][πΔ(0)/3(mK+mπ)]1/2, where Δ(0) is the propagator of the divergence of the strangeness-changing current at zero momentum transfer. Using the estimate of Mathur ...
