Revisiting the algebraic structure of the generalized uncertainty principle
Matteo Fadel, Michele Maggiore
We compare different formulations of the generalized uncertainty principle that have an underlying algebraic structure. We show that the formulation by Kempf, Mangano and Mann (KMM…
The Symmetrized Holographic Entropy Cone
Matteo Fadel, Sergio Hernández-Cuenca
The holographic entropy cone (HEC) characterizes the entanglement structure of quantum states which admit geometric bulk duals in holography. Due to its intrinsic complexity, to da…
Parity measurement in the strong dispersive regime of circuit quantum acoustodynamics
Uwe von Lüpke, Yu Yang, Marius Bild +3
Mechanical resonators are emerging as an important new platform for quantum science and technologies. A large number of proposals for using them to store, process, and transduce qu…
The time-energy uncertainty relation for quantum events
Matteo Fadel, Lorenzo Maccone
Textbook quantum mechanics treats time as a classical parameter, and not as a quantum observable with an associated Hermitian operator. For this reason, to make sense of usual time…
Full multipartite steering inseparability, genuine multipartite steering and monogamy for continuous variable systems
Run Yan Teh, Manuel Gessner, Margaret D. Reid +1
We derive inequalities sufficient to detect the genuine -partite steering of distinct systems. Here, we are careful to distinguish between the concepts of full -partite s…
Entanglement of Local Hidden States
Matteo Fadel, Manuel Gessner
Steering criteria are conditions whose violation excludes the possibility of describing the observed measurement statistics with local hidden state (LHS) models. When the available…
Detecting Einstein-Podolsky-Rosen steering in non-Gaussian spin states from conditional spin-squeezing parameters
Jiajie Guo, Feng-Xiao Sun, Daoquan Zhu +3
We present an experimentally practical method to reveal Einstein-Podolsky-Rosen steering in non-Gaussian spin states by exploiting a connection to quantum metrology. Our criterion…
Number-phase uncertainty relations and bipartite entanglement detection in spin ensembles
Giuseppe Vitagliano, Matteo Fadel, Iagoba Apellaniz +4
We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays t…
Machine Learning Universal Bosonic Functionals
Jonathan Schmidt, Matteo Fadel, Carlos L. Benavides-Riveros
The one-body reduced density matrix plays a fundamental role in describing and predicting quantum features of bosonic systems, such as Bose-Einstein condensation. The recently…
Entanglement quantification in atomic ensembles
Matteo Fadel, Ayaka Usui, Marcus Huber +2
Entanglement measures quantify nonclassical correlations present in a quantum system, but can be extremely difficult to calculate, even more so, when information on its state is li…
Bell correlations in a split two-mode-squeezed Bose-Einstein condensate
Jonas Kitzinger, Xin Meng, Matteo Fadel +4
We propose and analyze a protocol for observing a violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality using two spatially separated Bose-Einstein condensates (BECs).…
