Broadband pseudothermal states with tunable spectral coherence generated via nonlinear optics
Nicolás Quesada, Agata M. Brańczyk
It is well known that the reduced state of a two-mode squeezed vacuum state is a thermal state---i.e. a state whose photon-number statistics obey a geometric distribution. More exo…
Exact Markovian and non-Markovian time dynamics in waveguide QED: collective interactions, bound states in continuum, superradiance and subradiance
Fatih Dinc, İlke Ercan, Agata M. Brańczyk
We develop a formalism for modelling exact time dynamics in waveguide quantum electrodynamics (QED) using the real-space approach. The formalism does not assume any specific config…
Design Considerations for High-purity Heralded Single Photon Sources
Francesco Graffitti, Jérémy Kelly-Massicotte, Alessandro Fedrizzi +1
When building a parametric downconversion photon-pair source with spectrally separable photons, e.g. for making high-purity heralded single photons, two practical issues must be ac…
Gaussian functions are optimal for waveguided nonlinear-quantum-optical processes
Nicolás Quesada, Agata M. Brańczyk
Many nonlinear optical technologies require the two-mode spectral amplitude function that describes them---the \emph{joint spectral amplitude} (JSA)---to be separable. We prove tha…
