Classical and quantum mechanics across representations: an operational reading of the Wigner Weyl correspondence
Samuel Schlegel, Borivoje Dakić, Flavio Del Santo
The physical content of a theory is not intrinsically tied to any single mathematical formalism. Both classical and quantum mechanics admit equivalent representations, notably in p…

Gravitational Entanglement in Optomechanics: Distinguishing Classical and Quantum Models
Samuel Schlegel, Ankit Kumar, Tomasz Paterek +1
Observation of gravitationally induced quantum entanglement is often interpreted as a direct evidence of non-classical gravity. While the form and the degree of non-classicality ha…

Entanglement without Quantum Mechanics: Operational Constraints on the Quantum Signature
Samuel Schlegel, Borivoje Dakić, Flavio Del Santo
Entanglement is often regarded as an inherently quantum feature. We show that this does not have to be the case: under restricted operational access, classical correlations can app…
