Optimizing for an arbitrary perfect entangler. II. Application
Michael H. Goerz, Giulia Gualdi, Daniel M. Reich +7
The difficulty of an optimization task in quantum information science depends on the proper mathematical expression of the physical target. Here we demonstrate the power of optimiz…
Quantum Speed Limit and Optimal Control of Many-Boson Dynamics
Ioannis Brouzos, Alexej I. Streltsov, Antonio Negretti +4
We extend the concept of quantum speed limit -- the minimal time needed to perform a driven evolution -- to complex interacting many-body systems. We investigate a prototypical man…
A positive tensor network approach for simulating open quantum many-body systems
A. H. Werner, D. Jaschke, P. Silvi +4
Open many-body quantum systems play an important role in quantum optics and condensed-matter physics, and capture phenomena like transport, interplay between Hamiltonian and incohe…
Ultrasensitive Magnetometer Using a Single Atom
I. Baumgart, J. -M. Cai, A. Retzker +2
Precision sensing, and in particular high precision magnetometry, is a central goal of research into quantum technologies. For magnetometers, often trade-offs exist between sensiti…
Scalable reconstruction of unitary processes and Hamiltonians
M. Holzäpfel, T. Baumgratz, M. Cramer +1
Based on recently introduced efficient quantum state tomography schemes, we propose a scalable method for the tomography of unitary processes and the reconstruction of one-dimensio…

We present theoretical proposals for two-dimensional nuclear magnetic resonance spectroscopy protocols based on Nitrogen-vacancy (NV) centers in diamond that are strongly coupled t…
Two-dimensional spectroscopy for the study of ion Coulomb crystals
A. Lemmer, C. Cormick, C. T. Schmiegelow +2
Ion Coulomb crystals are currently establishing themselves as a highly controllable test-bed for mesoscopic systems of statistical mechanics. The detailed experimental interrogatio…
