One-axis twisting as a method of generating many-body Bell correlations
Marcin Płodzień, Maciej Lewenstein, Emilia Witkowska +1
We demonstrate that the one-axis twisting (OAT), a versatile method of creating non-classical states of bosonic qubits, is a powerful source of many-body Bell correlations. We deve…
Many-body Bell inequalities for bosonic qubits
Jan Chwedenczuk
Since John Bell formulated his paramount inequality for a pair of spin- particles, quantum mechanics has been confronted with the postulates of local realism with various equi…
Many-body nonlocality as a resource for quantum-enhanced metrology
Artur Niezgoda, Jan Chwedenczuk
We demonstrate that a many-body nonlocality is a resource for ultra-precise metrology. This result is achieved by linking the sensitivity of a quantum sensor with a combination of…
Detection of Bell correlations at finite temperature from matter-wave interference fringes
A. Niezgoda, J. Chwedenczuk, L. Pezze +1
We show that matter-wave interference fringes formed by two overlapping atomic clouds can yield information about the non-local Bell correlations. To this end, we consider a simple…
A strong Bell correlation witness between spatially separated pairs of atoms
D. K. Shin, B. M. Henson, S. S. Hodgman +3
The violation of a Bell inequality is a striking demonstration of how quantum mechanics contradicts local realism. Although the original argument was presented with a pair of spin…
Bell inequality, Einstein-Podolsky-Rosen steering and quantum metrology with spinor Bose-Einstein condensates
T. Wasak, J. Chwedenczuk
We propose an experiment, where the Bell inequality is violated in a many-body system of massive particles. The source of correlated atoms is a spinor Bose-Einstein condensat…
