Variational quantum algorithm for ergotropy estimation in quantum many-body batteries
Duc Tuan Hoang, Friederike Metz, Andreas Thomasen +3
Quantum batteries are predicted to have the potential to outperform their classical counterparts and are therefore an important element in the development of quantum technologies.…
Self-Correcting Quantum Many-Body Control using Reinforcement Learning with Tensor Networks
Friederike Metz, Marin Bukov
Quantum many-body control is a central milestone en route to harnessing quantum technologies. However, the exponential growth of the Hilbert space dimension with the number of qubi…
Variational Quantum Anomaly Detection: Unsupervised mapping of phase diagrams on a physical quantum computer
Korbinian Kottmann, Friederike Metz, Joana Fraxanet +1
One of the most promising applications of quantum computing is simulating quantum many-body systems. However, there is still a need for methods to efficiently investigate these sys…
Adiabatic critical quantum metrology cannot reach the Heisenberg limit even when shortcuts to adiabaticity are applied
Karol Gietka, Friederike Metz, Tim Keller +1
We show that the quantum Fisher information attained in an adiabatic approach to critical quantum metrology cannot lead to the Heisenberg limit of precision and therefore regular q…
Deep learning based quantum vortex detection in atomic Bose-Einstein condensates
Friederike Metz, Juan Polo, Natalya Weber +1
Quantum vortices naturally emerge in rotating Bose-Einstein condensates (BECs) and, similarly to their classical counterparts, allow the study of a range of interesting out-of-equi…
Universal and optimal coin sequences for high entanglement generation in 1D discrete time quantum walks
Aikaterini Gratsea, Friederike Metz, Thomas Busch
Entanglement is a key resource in many quantum information applications and achieving high values independently of the initial conditions is an important task. Here we address the…
Two-leg ladder Bose Hubbard models with staggered fluxes
Rashi Sachdeva, Friederike Metz, Manpreet Singh +2
We investigate the ground state properties of ultracold atoms trapped in a two-leg ladder potential in the presence of an artificial magnetic field in a staggered configuration. We…
