Coarse-grained self-testing
Irénée Frérot, Antonio Acín
Self-testing is a device-independent method that usually amounts to show that the maximal quantum violation of a Bell's inequality certifies a unique quantum state, up to some symm…
Comment on "Strong Quantum Darwinism and Strong Independence are Equivalent to Spectrum Broadcast Structure"
Alexandre Feller, Benjamin Roussel, Irénée Frérot +1
In a recent Letter [Phys. Rev. Lett. 122, 010403 (2019)], an equivalence is proposed between the so-called Spectrum Broadcast Structure for a system-multienvironment quantum state,…
Optimal entanglement witnesses: a scalable data-driven approach
Irénée Frérot, Tommaso Roscilde
Multipartite entanglement is the key resource allowing quantum devices to outperform their classical counterparts, and entanglement certification is fundamental to assess any quant…
Simulating twistronics without a twist
Tymoteusz Salamon, Alessio Celi, Ravindra W. Chhajlany +4
Rotational misalignment or twisting of two mono-layers of graphene strongly influences its electronic properties. Structurally, twisting leads to large periodic supercell structure…
Competing orders for the colloidal kagome ice: the importance of in-trap motion of the particles
Anne Le Cunuder, Irénée Frérot, Antonio Ortiz-Ambriz +1
Artificial ice systems have been designed to replicate paradigmatic phenomena observed in frustrated spin systems. Here we present a detailed theoretical analysis based on Monte-Ca…
Characterising two-sided quantum correlations beyond entanglement via metric-adjusted f-correlations
Marco Cianciaruso, Irénée Frérot, Tommaso Tufarelli +1
We introduce an infinite family of quantifiers of quantum correlations beyond entanglement which vanish on both classical-quantum and quantum-classical states and are in one-to-one…
Entanglement and fluctuations in the XXZ model with power-law interactions
Irénée Frérot, Piero Naldesi, Tommaso Roscilde
We investigate the ground-state properties of the XXZ model with interactions, describing spins interacting with long-range (LR) transverse (XX) ferromagnetic interactions…
Quantum variance: a measure of quantum coherence and quantum correlations for many-body systems
Irénée Frérot, Tommaso Roscilde
Quantum coherence is a fundamental common trait of quantum phenomena, from the interference of matter waves to quantum degeneracy of identical particles. Despite its importance, es…
Area law and its violation: A microscopic inspection into the structure of entanglement and fluctuations
Irénée Frérot, Tommaso Roscilde
Quantum fluctuations of local quantities can be a direct signature of entanglement in an extended quantum many-body system. Hence they may serve as a theoretical (as well as an exp…
