Vacuum entanglement probes for ultra-cold atom systems
Cisco Gooding, Allison Sachs, Robert B. Mann +1
This study explores the transfer of nonclassical correlations from an ultra-cold atom system to a pair of pulsed laser beams. Through nondestructive local probe measurements, we in…

Relativity and decoherence of spacetime superpositions
Joshua Foo, Robert B. Mann, Magdalena Zych
It is univocally anticipated that in a theory of quantum gravity, there exist quantum superpositions of semiclassical states of spacetime geometry. Such states could arise for exam…

Polytopes of Absolutely Wigner Bounded Spin States
Jérôme Denis, Jack Davis, Robert B. Mann +1
Quasiprobability has become an increasingly popular notion for characterising non-classicality in quantum information, thermodynamics, and metrology. Two important distributions wi…
