Super-Resolution Imaging with Multiparameter Quantum Metrology in Passive Remote Sensing
Emre Köse, Daniel Braun
We study super-resolution imaging theoretically using a distant n-mode interferometer in the microwave regime for passive remote sensing, used e.g., for satellites like the "soil m…
Quantum metrology with ultracold chemical reactions
Seong-Ho Shinn, Uwe R. Fischer, Daniel Braun
Chemical chain reactions are known to enable extremely sensitive detection schemes in chemical, biological, and medical analysis, and have even been used in the search for dark mat…
Benchmarking the performance of portfolio optimization with QAOA
Sebastian Brandhofer, Daniel Braun, Vanessa Dehn +6
We present a detailed study of portfolio optimization using different versions of the quantum approximate optimization algorithm (QAOA). For a given list of assets, the portfolio o…
Quantum-enhanced passive remote sensing
Emre Köse, Gerardo Adesso, Daniel Braun
We investigate theoretically the ultimate resolution that can be achieved with passive remote sensing in the microwave regime used e.g.~on board of satellites observing Earth, such…
Truncated moment sequences and a solution to the channel separability problem
Nadia Milazzo, Daniel Braun, Olivier Giraud
We consider the problem of separability of quantum channels via the Choi matrix representation given by the Choi-Jamiołkowski isomorphism. We explore three classes of separability…
