No extension of the Quantum Tensor Product admits a Superposition principle
Vincenzo Fiorentino, Kuntal Sengupta
Textbook quantum superposition refers to the feature that certain linear combinations of Hilbert space rays, each representing a valid quantum state, are themselves valid states. T…
Gleason's Theorem for a Qubit as Part of a Composite System
Vincenzo Fiorentino, Stefan Weigert
We extend Gleason's theorem to the two-dimensional Hilbert space of a qubit by invoking the standard axiom that describes composite quantum systems. The tensor-product structure al…
Beyond the Projection Postulate and Back: Quantum Theories with Generalised State-Update Rules
Vincenzo Fiorentino, Stefan Weigert
Are there consistent and physically reasonable alternatives to the projection postulate? Does it have unique properties compared with acceptable alternatives? We answer these quest…
A Quantum Theory with Non-Collapsing Measurements
Vincenzo Fiorentino, Stefan Weigert
A collapse-free version of quantum theory is examined to systematically study the role of the projection postulate. This foil theory assumes "passive" measurements that do not upda…
