Variational quantum simulation using non-Gaussian continuous-variable systems
Paolo Stornati, Antonio Acin, Ulysse Chabaud +3
This work introduces a novel approach to quantum simulation by leveraging continuous-variable systems within a photonic hardware-inspired framework. The primary focus is on simulat…
Tight Bell inequalities with no quantum violation from qubit unextendible product bases
R. Augusiak, T. Fritz, M. Kotowski +3
We investigate the relation between unextendible product bases (UPB) and Bell inequalities found recently in [R. Augusiak et al., Phys. Rev. Lett. 107, 070401 (2011)]. We first rev…
Bell inequalities with no quantum violation and unextendible product bases
R. Augusiak, J. Stasińska, C. Hadley +3
The strength of classical correlations is subject to certain constraints, commonly known as Bell inequalities. Violation of these inequalities is the manifestation of nonlocality--…
Optimal estimation of quantum dynamics
A. Acin, E. Jane, G. Vidal
We construct the optimal strategy for the estimation of an unknown unitary transformation . This includes, in addition to a convenient measurement on a probe system, fi…
Three-qubit pure-state canonical forms
A. Acin, A. Andrianov, E. Jane +1
In this paper we analyze the canonical forms into which any pure three-qubit state can be cast. The minimal forms, i.e. the ones with the minimal number of product states built fro…
Three-party entanglement from positronium
A. Acin, J. I. Latorre, P. Pascual
The decay of ortho-positronium into three photons produces a physical realization of a pure state with three-party entanglement. Its quantum correlations are analyzed using recent…
Optimal distillation of a GHZ state
A. Acin, E. Jane, W. Dur +1
We present the optimal local protocol to distill a Greenberger-Horne-Zeilinger (GHZ) state from a single copy of any pure state of three qubits.
Generalized Schmidt decomposition and classification of three-quantum-bit states
A. Acin, A. Andrianov, L. Costa +3
We prove for any pure three-quantum-bit state the existence of local bases which allow to build a set of five orthogonal product states in terms of which the state can be written i…
Optimal estimation of two-qubit pure-state entanglement
A. Acin, R. Tarrach, G. Vidal
We present optimal measuring strategies for the estimation of the entanglement of unknown two-qubit pure states and of the degree of mixing of unknown single-qubit mixed states, of…
