Superconducting Nanowire Single-Photon Detector Arrays for the Near- to Mid-Infrared

October 31, 2023
Author(s)
Benedikt Hampel, Richard Mirin, Sae Woo Nam, Varun Verma
Superconducting Nanowire Single-Photon Detectors (SNSPDs) are excellent devices for the analysis of faint light from the ultraviolet to the mid-infrared. Recent developments push their broad wavelength bandwidth further into the mid-infrared towards 20 μm

A superconducting nanowire single-photon camera with 400,000 pixels

Bakhrom Oripov, Dana Rampini, Jason Allmaras, Matt Shaw, Sae Woo Nam, Boris Korzh, Adam McCaughan
For the past 50 years, superconducting detectors have offered exceptional sensitivity and speed for detecting faint electromagnetic signals in a wide range of applications. These detectors operate at very low temperatures and generate a minimum of excess

Trap-Integrated Superconducting Nanowire Single-Photon Detectors with Improved RF Tolerance for Trapped-Ion Qubit State Readout

April 24, 2023
Author(s)
Benedikt Hampel, Daniel Slichter, Dietrich Leibfried, Richard Mirin, Sae Woo Nam, Varun Verma
State readout of trapped-ion qubits with trap-integrated detectors can address important challenges for scalable quantum computing, but the strong radio frequency (rf) electric fields used for trapping can impact detector performance. Here, we report on

Demonstration of Superconducting Optoelectronic Single-Photon Synapses

October 6, 2022

Saeed Khan, Bryce Primavera, Jeff Chiles, Adam McCaughan, Sonia Buckley, Alexander Tait, Adriana Lita, John Biesecker, Anna Fox, David Olaya, Richard Mirin, Sae Woo Nam, Jeff Shainline
Superconducting optoelectronic hardware is being explored as a path towards artificial spiking neural networks with unprecedented scales of complexity and computational ability. Such hardware combines integrated-photonic components for few-photon, light

Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

New Constraints on Dark Photon Dark Matter with Superconducting Nanowire Detectors in an Optical Haloscope

June 10, 2022

Jeff Chiles, Ilya Charaev, Asimina Arvanitaki, Masha Baryakhtar, junwu huang, Robert Lasenby, Ken Van Tillburg, Alexana Roshko, George Burton, Marco Colangelo, Sae Woo Nam, Karl Berggren
Uncovering the nature of dark matter is one of the most important goals of particle physics. Light bosonic particles, such as the dark photon, are well-motivated candidates: they are generically long-lived, weakly-interacting, and naturally produced in the

Quantum computational advantage with a programmable photonic processor

L.S. Madsen, F. Laudenbach, M.F. Askarani, F. Rortais, T. Vincent, J.F.F. Bulmer, F.M. Miatto, L. Neuhaus, L.G. Helt, Matthew Collins, Adriana Lita, Thomas Gerrits, Sae Woo Nam, V.D. Vaidya, M. Menotti, I. Dhand, Zachary Vernon, N. Quesada, J. Lavoie
The demonstration of quantum computational advantage is a key milestone in the race to build a fully functional quantum computer. This milestone involves showing that a particular quantum device can perform a well-defined computational task in a manner
