Practical protein-pocket hydration-site prediction for drug discovery on a quantum computer
Daniele Loco, Kisa Barkemeyer, Andre R. R. Carvalho +1
Demonstrating the practical utility of Noisy Intermediate-Scale Quantum (NISQ) hardware for recurrent tasks in Computer-Aided Drug Discovery is of paramount importance. We tackle t…
Energy-time entanglement from a resonantly driven quantum dot three-level system
M. Hohn, K. Barkemeyer, M. von Helversen +8
Entanglement is a major resource in advanced quantum technology, where it can enable secure exchange of information over large distances. Energy-time entanglement is particularly a…
Heisenberg treatment of multiphoton pulses in waveguide QED with time-delayed feedback
Kisa Barkemeyer, Andreas Knorr, Alexander Carmele
The dynamics of waveguide-QED systems involving coherent time-delayed feedback give rise to a hierarchy of multi-time correlations within the Heisenberg picture due to the induced…
Boosting energy-time entanglement using coherent time-delayed feedback
Kisa Barkemeyer, Marcel Hohn, Stephan Reitzenstein +1
The visibility of the two-photon interference in the Franson interferometer serves as a measure of the energy-time entanglement of the photons. We propose to control the visibility…
Strongly entangled system-reservoir dynamics with multiphoton pulses beyond the two-excitation limit: Exciting the atom-photon bound state
Kisa Barkemeyer, Andreas Knorr, Alexander Carmele
Within the matrix product state framework, we study the non-Markovian feedback dynamics of a two-level system interacting with the electromagnetic field inside a semi-infinite wave…
Entanglement robustness to excitonic spin precession in a quantum dot
Samir Bounouar, Gabriel Rein, Kisa Barkemeyer +9
A semiconductor quantum dot (QD) is an attractive resource to generate polarization-entangled photon pairs. We study the excitonic spin precession (flip-flop) in a family of QDs wi…
Revisiting Quantum Feedback Control: Disentangling the Feedback-induced Phase from the Corresponding Amplitude
Kisa Barkemeyer, Regina Finsterhölzl, Andreas Knorr +1
Coherent time-delayed feedback allows the control of a quantum system and its partial stabilization against noise and decoherence. The crucial and externally accessible parameters…
