High-gain effects in broadband continuous-wave parametric down conversion sources and measurements with undetected photons
Martin Houde, Franz Roeder, Christine Silberhorn +2
We study theoretically how high-gain effects affect the measurement outcome of visible signal spectra in undetected photon measurement schemes. We consider two interferometric conf…
Quantum Fisher information analysis for absorption measurements with undetected photons
Martin Houde, Franz Roeder, Christine Silberhorn +2
We theoretically compare the quantum Fisher information (QFI) for three configurations of absorption spectroscopy with undetected idler photons: an SU(1,1) interferometer with inte…
Ultrashort-pulse-pumped, single-mode type-0 squeezers in lithium niobate nanophotonics
Martin Houde, Liam Beaudoin, Robert Kwolek +3
We present design principles for ultrashort-pulse, type-0 phase-matched optical parametric amplifiers to generate and measure spectrally pure degenerate squeezed light. We consider…
Accurate Unsupervised Photon Counting from Transition Edge Sensor Signals
Nicolas Dalbec-Constant, Guillaume Thekkadath, Duncan England +3
We compare methods for signal classification applied to voltage traces from transition-edge sensors (TES) which are photon-number resolving detectors fundamental for accessing quan…
