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.…
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…
