A discussion on particle number and quantum indistinguishability
(Springer, 2007-12)
The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory. Regarding this fact, some ...
Contextuality and Indistinguishability
(Molecular Diversity Preservation International, 2017-08)
It is well known that in quantum mechanics we cannot always define consistently properties that are context independent. Many approaches exist to describe contextual properties, such as Contextuality by Default (CbD), sheaf ...
Role of indistinguishability in interferometric phase estimation
(American Physical Society, 2019-12-23)
We report a theoretical and experimental study on the role of indistinguishability in the estimation of an interferometric phase. In particular, we show that the quantum Fisher information, which limits the maximum precision ...
Indistinguishability and negative probabilities
(Multidisciplinary Digital Publishing Institute, 2020-07-20)
In this paper, we examined the connection between quantum systems’ indistinguishability and signed (or negative) probabilities. We do so by first introducing a measure-theoretic definition of signed probabilities inspired ...
A formal framework for the study of the notion of undefined particle number in quantum mechanics
(Springer, 2015-01)
It is usually stated that quantum mechanics presents problems with the identity of particles, the most radical position—supported by E. Schrödinger—asserting that elementary particles are not individuals. But the subject ...
