Entangled symmetric states and copositive matrices
Carlo Marconi, Albert Aloy, Jordi Tura +1
Entanglement in symmetric quantum states and the theory of copositive matrices are intimately related concepts. For the simplest symmetric states, i.e., the diagonal symmetric (DS)…
Bounding the fidelity of quantum many-body states from partial information
Matteo Fadel, Albert Aloy, Jordi Tura
We formulate an algorithm to lower bound the fidelity between quantum many-body states only from partial information, such as the one accessible by few-body observables. Our method…
Robust self-testing of steerable quantum assemblages and its applications on device-independent quantum certification
Shin-Liang Chen, Huan-Yu Ku, Wenbin Zhou +2
Given a Bell inequality, if its maximal quantum violation can be achieved only by a single set of measurements for each party or a single quantum state, up to local unitaries, one…
The quantum marginal problem for symmetric states: applications to variational optimization, nonlocality and self-testing
Albert Aloy, Matteo Fadel, Jordi Tura
In this paper, we present a method to solve the quantum marginal problem for symmetric -level systems. The method is built upon an efficient semi-definite program that determine…
