Scanless quantum Fourier-transform mid-infrared spectroscopy for rapid high-sensitivity hyperspectral mapping
Paul Gattinger, Bettina Heise, Andreas W. Schell +3
Fourier-transform infrared (FTIR) spectroscopy is a well-established technique for qualitative and quantitative chemical analysis. Classical FTIR systems rely, however, on direct m…
Quantum metrology with undetected mid-infrared photons for applied non-destructive testing
Paul Gattinger, Andreas W. Schell, Maja Buchegger +2
The paper presents a quantum metrology approach that uses undetected mid‑infrared photons generated via spontaneous parametric down‑conversion to perform mid‑IR spectroscopy, micro…
Limits to the validity of gravitational redshift as a quantum-optical multimode mixer
Nils Leber, Luis Adrián AlanÃs RodrÃguez, Alessandro Ferreri +2
We analyze the domain of validity of a quantum optical model that describes the effects of gravitational redshift on the quantum state of photons that propagate in curved spacetime…
Quantum Fourier Transform Infrared Spectroscopy: Evaluation, Benchmarking and Prospects
Paul Gattinger, Andreas W. Schell, Sven Ramelow +2
Sensing with undetected photons has enabled new, unconventional approaches to Fourier transform infrared (FTIR) spectroscopy. Leveraging properties of non-degenerated entangled pho…
