Differential magnetometry with partially flipped Dicke states
Iagoba Apellaniz, Manuel Gessner, Géza Tóth
We study magnetometry of gradients and homogeneous background fields along the three orthogonal directions using two spatially separated spin ensembles. We derive trade-off relatio…
Metrological Sensitivity beyond Gaussian Limits with Cubic Phase States
Jiajie Guo, Shuheng Liu, Boxuan Jing +2
Cubic phase states provide the essential non-Gaussian resource for continuous-variable quantum computing. We show that they also offer significant potential for quantum metrology,…
Complete characterisation of state conversions by work extraction
Chung-Yun Hsieh, Manuel Gessner
We introduce a thermodynamic work extraction task that describes the energy storage enhancement of quantum systems, which is naturally related to quantum battery's charging process…
General quantum resources provide advantages in work extraction tasks
Chung-Yun Hsieh, Manuel Gessner
In developing quantum science and technologies, it is essential to demonstrate the so-called quantum advantages, which are performances that can be achieved only with the assistanc…
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…
