Violation of local realism with spatially multimode parametric down-conversion pumped by spatially incoherent light Open

Cheng Li, Jeremy Upham, Boris Braverman, Robert W. Boyd · 2025

We experimentally demonstrate a violation of local realism with highly spatially multimode polarization-entangled two-photon states produced by spontaneous parametric down-conversion (SPDC) pumped by a spatially incoherent light source-a l…

Imaging cross-degree-of-freedom structures in biphoton spatial-polarization hyperentanglement Open

Cheng Li, Girish S. Kulkarni, Isaac Soward, Yingwen Zhang, Jeremy Upham , et al. · 2025

Hyperentanglement, which refers to entanglement across more than one degree of freedom (DoF), is a valuable resource in photonic quantum technology. Although hyperentangled states inherently facilitate access to high-dimensional Hilbert sp…

Efficient characterization of spatial Schmidt modes of multiphoton entangled states produced from high-gain parametric down-conversion Open

Mahtab Amooei, Girish S. Kulkarni, Jeremy Upham, Robert W. Boyd · 2024

The ability to efficiently characterize the spatial correlations of entangled states of light is critical for applications of many quantum technologies such as quantum imaging. Here, we demonstrate highly efficient theoretical and experime…

Fast control of the transverse structure of a light beam using acousto-optic modulators Open

Mahdieh Chartab Jabbari, Cheng Li, Xialin Liu, R. Margoth Córdova‐Castro, Boris Braverman , et al. · 2024

Fast, reprogrammable control over the transverse structure of light beams plays an essential role in applications such as structured illumination microscopy, optical trapping, and quantum information processing. Existing technologies, such…

Roadmap on photonic metasurfaces Open

Sebastian A. Schulz, Rupert F. Oulton, Mitchell Kenney, Andrea Alù, Isabelle Staude , et al. · 2024

Here we present a roadmap on Photonic metasurfaces. This document consists of a number of perspective articles on different applications, challenge areas or technologies underlying photonic metasurfaces. Each perspective will introduce the…

Photon number resolving detection with a single-photon detector and adaptive storage loop Open

Nicholas M. Sullivan, Boris Braverman, Jeremy Upham, Robert W. Boyd · 2024

Photon number resolving (PNR) measurements are beneficial or even necessary for many applications in quantum optics. Unfortunately, PNR detectors are usually large, slow, expensive, and difficult to operate. However, if the input signal is…

Modeling beam propagation in a moving nonlinear medium Open

Ryan Hogan, Giulia Marcucci, Akbar Safari, A. Nicholas Black, Boris Braverman , et al. · 2024

Fully describing light propagation in a rotating, anisotropic medium with thermal nonlinearity requires modeling the interplay between nonlinear refraction, birefringence, and the nonlinear group index. Incorporating these factors into a g…

Photon Number Resolving Detection with a Single-Photon Detector and Adaptive Storage Loop Open

Nicholas M. Sullivan, Boris Braverman, Jeremy Upham, Robert W. Boyd · 2023

Photon number resolving (PNR) measurements are beneficial or even necessary for many applications in quantum optics. Unfortunately, PNR detectors are usually large, slow, expensive, and difficult to operate. However, if the input signal is…
