A multidimensional integrated quantum photonic platform able to generate, control, and analyze high-dimensional entanglement is demonstrated, and a programmable bipartite entangled system is realized with dimensions up to 15 × 15 on a large-scale silicon photonics quantum circuit.Expand

This work shows that the runtime of the proposed general-purpose quantum algorithm for preparing ground states of quantum Hamiltonians from a given trial state is exponentially better as a function of the allowed error, and at least quadratically better as of the overlap with the trial state.Expand

A simplified, experimentally accessible form of Bell inequalities is derived and can be tested by measuring total spin components, opening the way to the experimental detection of many-body nonlocality, for instance with atomic ensembles.Expand

This paper presents the Talavera Manifesto for quantum software engineering and programming. This manifesto collects some principles and commitments about the quantum software engineering and… Expand

Entanglement witnesses (EWs) constitute one of the most important entanglement detectors in quantum systems. Nevertheless, their complete characterization, in particular with respect to the notion of… Expand

This work finds the passive states lying in the other extreme, i.e., those that maximize the energy for a given entropy, which it is shown also minimize the entropy when the energy is fixed.Expand

This work introduces a class of Bell inequalities valid for an arbitrary number of measurements and results, derive analytically their tight classical, nonsignaling, and quantum bounds and prove that the latter is attained by maximally entangled states.Expand

A set of local-realism tests using human choices, which avoids assumptions about predictability in physics and closes the ‘freedom-of-choice loophole’, which contradicts the Einstein–Podolsky–Rosen worldview of local realism.Expand

This work provides a general construction of genuinely multipartite entangled states that do not display genuinely multipartsite nonlocality, thus proving that entanglement and nonlocability are inequivalent for any number of parties.Expand
