Photonic integrated circuits with second-order (χ (2)) nonlinearities are rapidly scaling to
remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear …

Realization of a room-temperature ultrafast photon-number-resolving quantum
nondemolition (QND) measurement would have significant implications for photonic …

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

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

The propagation of ultrafast pulses in dispersion-engineered waveguides, exhibiting strong
field confinement in both space and time, is a promising avenue towards single-photon …

We study theoretically how the brightness of the pumps, with fixed profiles, affects the
temporal mode structure of squeezed states generated by fixed parametric waveguided …

High-rate, high-fidelity entanglement distribution is essential to the creation of a quantum
internet, but recent achievements in fiber (248 km at a 9-s− 1 rate) and satellite-based (1200 …

Over the last few decades, nonlinear optics has become significantly more nonlinear,
traversing nearly a billionfold improvement in energy efficiency, with ultrafast nonlinear …

We develop a formalism to describe squeezed light with large spectral-temporal
correlations. This description is valid in all regimes, but is especially applicable in the long …

We present a multimode theory of squeezed-state generation in resonant systems valid for
arbitrary pump power and including pump depletion. The Hamiltonian is written in terms of …
