Spinor Bose-Einstein condensate as an analog simulator of molecular bending vibrations
Ayaka Usui, Artur Niezgoda, Manuel Gessner
We demonstrate that spinor Bose-Einstein condensates (BEC) can be operated as an analog simulator of the two-dimensional vibron model. This algebraic model for the description of b…
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…
Twist-and-store entanglement in bimodal and spin-1 Bose-Einstein condensates
Artur Niezgoda, Emilia Witkowska, Safoura Sadat Mirkhalaf
A scheme for dynamical stabilization of entanglement quantified by the quantum Fisher information is analyzed numerically and analytically for bimodal and spin-1 Bose-Einstein cond…
Characterizing quantum correlations in spin chains
Artur Niezgoda, Miłosz Panfil, Jan Chwedeńczuk
The growth in the demand for precisely crafted many-body systems of spin- particles/qubits is due to their top-notch versatility in application-oriented quantum-enhanced proto…
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…
Optimal atomic interferometry robust to detection noise using spin-1 atomic condensates
Artur Niezgoda, Dariusz Kajtoch, Joanna Dziekańska +1
Implementation of the quantum interferometry concept to spin-1 atomic Bose-Einstein condensates is analyzed by employing a polar state evolved in time. In order to identify the bes…
