Photons have been a flagship system for studying quantum mechanics, advancing quantum
information science, and develo** quantum technologies. Quantum entanglement …

Entangled photon sources are desirable and key elements for photonic quantum information
processing. The spontaneous parametric down‐conversion (SPDC) process is a convenient …

Squeezed light generation has come of age. Significant advances on squeezed light
generation have been made over the last 30 years—from the initial, conceptual experiment …

Field-orthogonal temporal modes of photonic quantum states provide a new framework for
quantum information science (QIS). They intrinsically span a high-dimensional Hilbert space …

We review the rapid recent progress in single-photon sources based on multiplexing
multiple probabilistic photon-creation events. Such multiplexing allows higher single-photon …

We report demonstrations of both quadrature-squeezed vacuum and photon number
difference squeezing generated in an integrated nanophotonic device. Squeezed light is …

We report the observation of all-optical squeezing in an on-chip monolithically integrated
CMOS-compatible platform. Our device consists of a low-loss silicon nitride microring optical …

The development of large-scale optical quantum information processing circuits ground on
the stability and reconfigurability enabled by integrated photonics. We demonstrate a …

Broadband multimode squeezers constitute a powerful quantum resource with promising
potential for different applications in quantum information technologies such as information …

We generate pulsed, two-mode squeezed states in a single spatiotemporal mode with mean
photon numbers up to 20. We directly measure photon-number correlations between the two …
