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
Quantum entanglement is defined as nonseparability of density operators, yet experimental phase-space statistics alone cannot distinguish classical from quantum sources, so classic…
