Noise assisted Ramsey interferometry
U. Dorner
I analyze a metrological strategy for improving the precision of frequency estimation via Ramsey interferometry with strings of atoms in the presence of correlated dephasing. This…
Dissipative quantum light field engineering
Martin Kiffner, Uwe Dorner, Dieter Jaksch
We put forward a dissipative preparation scheme for strongly correlated photon states. Our approach is based on a two-photon loss mechanism that is realised via a single four-level…
The Optical Excitation of Zigzag Carbon Nanotubes with Photons Guided in Nanofibers
S. Broadfoot, U. Dorner, D. Jaksch
We consider the excitation of electrons in semiconducting carbon nanotubes by photons from the evanescent field created by a subwavelength-diameter optical fiber. The strongly chan…
Quantum frequency estimation with trapped ions and atoms
U. Dorner
We discuss strategies for quantum enhanced estimation of atomic transition frequencies with ions stored in Paul traps or neutral atoms trapped in optical lattices. We show that onl…
Quantum metrology with imperfect states and detectors
Animesh Datta, Lijian Zhang, Nicholas Thomas-Peter +3
Quantum enhancements of precision in metrology can be compromised by system imperfections. These may be mitigated by appropriate optimization of the input state to render it robust…
Real-world Quantum Sensors: Evaluating Resources for Precision Measurement
Nicholas Thomas-Peter, Brian J Smith, Animesh Datta +3
Quantum physics holds the promise of enabling certain tasks with better performance than possible when only classical resources are employed. The quantum phenomena present in many…
