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…

Parametric processes in nonlinear structures with reflections: an asymptotic-field approach

Tadeu Tassis, Salvador Poveda-Hospital, Nicolás Quesada +1

The generation of engineered quantum states of light via nonlinear processes is fundamental for quantum technologies based on photons. Although embedding nonlinear materials within…

Parametric processes in nonlinear structures with reflections: a transfer matrix method approach

Salvador Poveda-Hospital, Tadeu Tassis, Yves-Alain Peter +2

The Transfer Matrix Method is a powerful numerical tool for simulating wave propagation in layered media. It has been widely applied in many fields, although its use is typically r…

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…

Gain-induced group delay in spontaneous parametric down-conversion

Guillaume Thekkadath, Martin Houde, Duncan England +4

Strongly-driven nonlinear optical processes such as spontaneous parametric down-conversion and spontaneous four-wave mixing can produce multiphoton nonclassical beams of light whic…

Matrix decompositions in Quantum Optics: Takagi/Autonne, Bloch-Messiah/Euler, Iwasawa, and Williamson

Martin Houde, Will McCutcheon, Nicolás Quesada

In this note we summarize four important matrix decompositions commonly used in quantum optics, namely the Takagi/Autonne, Bloch-Messiah/Euler, Iwasawa, and Williamson decompositio…

Perfect pulsed inline twin-beam squeezers

Martin Houde, Nicolás Quesada

Perfect inline squeezers are both spectrally pure and have identical input and output temporal modes, allowing one to squeeze an arbitrary input quantum state in the sole input mod…
