The superb supersinglet

Gabriele Cobucci, Armin Tavakoli, Alexander Bernal +1

Multipartite systems of high-dimensional particles can host forms of quantum entanglement inaccessible to qubit systems. A particularly fascinating class is formed by the fully ant…

Detecting high-dimensional entanglement with simple measurements

Suraj Goel, Alexander Bernal, Gabriele Cobucci +3

The standard benchmark for high-dimensional entanglement is the number of dimensions in which entanglement must be present in order to generate the state. This is called the Schmid…

Quantum coherence as randomness under classical control

Gabriele Cobucci, Nicola D'Alessandro, Raphael Brinster +3

Quantum states that do not commute exhibit coherence, but only when the device preparing them is assumed to be unaffected by classical parameters inaccessible to the experimenter.…

Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics

Yoav Afik, Federica Fabbri, Matthew Low +68

Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…

Operationally classical simulation of quantum states

Gabriele Cobucci, Alexander Bernal, Martin J. Renner +1

A classical state-preparation device cannot generate states in relative superposition. We introduce classical models in which devices that are individually unable to generate state…

Absolute dimensionality of quantum ensembles

Alexander Bernal, Gabriele Cobucci, Martin J. Renner +1

The dimension of a quantum state is traditionally seen as the number of superposed distinguishable states in a given basis. We propose an absolute, i.e.~basis-independent, notion o…

Entanglement and Bell inequality violation in vector diboson systems produced in decays of spin-0 particles

Alexander Bernal, Paweł Caban, Jakub Rembieliński

We discuss entanglement and the violation of the CGLMP inequality in a system of two vector bosons produced in the decay of a spin-0 particle. We assume the most general CPT conser…

Quantum tomography of helicity states for general scattering processes

Alexander Bernal

Quantum tomography has become an indispensable tool in order to compute the density matrix of quantum systems in Physics. Recently, it has further gained importance as a basic…

Entanglement and Bell inequalities violation in with anomalous coupling

Alexander Bernal, Paweł Caban, Jakub Rembieliński

We discuss entanglement and violation of Bell-type inequalities for a system of two bosons produced in Higgs decays. We take into account beyond the Standard Model (anomalous)…
