We present an approach to building interferometric telescopes using ideas of quantum
information. Current optical interferometers have limited baseline lengths, and thus limited …

We review the concepts of temporal modes (TMs) in quantum optics, highlighting Roy
Glauber's crucial and historic contributions to their development, and their growing …

Frequency conversion (FC) and type-II parametric down-conversion (PDC) processes serve
as basic building blocks for the implementation of quantum optical experiments: type-II PDC …

The examination of entanglement across various degrees of freedom has been pivotal in
augmenting our understanding of fundamental physics, extending to high dimensional …

Indistinguishability is a crucial element for quantum interference in scalable quantum
information processing. Here, we demonstrate the ability to erase the distinguishability of a …

In this Letter we demonstrate frequency conversion in the single-photon regime through
Bragg-scattering four-wave mixing with near-unit efficiency in a 750 m long commercially …

The frequency conversion of light has proved to be a crucial technology for communication,
spectroscopy, imaging, and signal processing. In the quantum regime, it also offers great …

Quantum frequency conversion (FC) in nonlinear optical media is a powerful tool for
temporal-mode selective manipulation of light. Recent attempts at achieving high mode …

Backward-wave three-wave mixing is a difficult χ^(2) interaction to observe, because it
requires ultrashort poling periods to achieve phasematching. Having realized sub …

Nondegenerate four-wave mixing driven by two pulsed pumps transfers the quantum state of
an input signal pulse to an output idler pulse, which is a frequency-converted and reshaped …
