Applications of Quantum Randomness: From Rabi Oscillations to Fourier Axis Controlling the Musical Timbre
Reiko Yamada, Samuele Grandi, Gorka Muñoz-Gil +3
Randomness has attracted great interest in the field of music composition for quite some time. As early as 1962, Iannis Xenakis started exploring a stochastic approach to randomnes…
Inferring Nonlinear Many-Body Bell Inequalities From Average Two-Body Correlations: Systematic Approach for Arbitrary Spin-j Ensembles
Guillem Müller-Rigat, Albert Aloy, Maciej Lewenstein +1
Violating Bell's inequalities (BIs) allows one to certify the preparation of entangled states from minimal assumptions -- in a device-independent manner. Finding BIs tailored to ma…
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)…
Storage capacity and learning capability of quantum neural networks
Maciej Lewenstein, Aikaterini Gratsea, Andreu Riera-Campeny +3
We study the storage capacity of quantum neural networks (QNNs) described as completely positive trace preserving (CPTP) maps, which act on an -dimensional Hilbert space. We dem…
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…
Optimization of device-independent witnesses of entanglement depth from two-body correlators
Jordi Tura, Albert Aloy, Flavio Baccari +3
In a recent work [A. Aloy et al. arXiv:1807:06027 (2018)] we have considered the characterization of entanglement depth, from a device-independent perspective, in a quantum many-bo…
