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…
Certifying coherence in quantum devices 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.…
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…
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…
Entanglement and Bell inequality violation in vector diboson systems produced in decays of spin-0 particles
Alexander Bernal, PaweÅ Caban, Jakub RembieliÅski
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…
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…
