Quasiparticle recombination in hotspots in superconducting current-carrying nanowires

August 6, 2015
Author(s)
Alex Kozorezov, Colin Lambert, Francesco Marsili, Martin Stevens, Varun Verma, Jeffrey A. Stern, Rob Horansky, Shellee D. Dyer, Shannon Duff, David P. Pappas, Adriana Lita, Matthew D. Shaw, Richard Mirin, Sae Woo Nam
We describe a kinetic model of recombination of nonequilibrium quasiparticles generated by single photon absorption in superconducting current-carrying nanowires. The model is developed to interpret two-photon detection experiments in which a single photon

Quantum-correlated photon pairs generated in commercial 45 nm complementary metal-oxide semiconductor microelectronics

Cale M. Gentry, Jeff Shainline, Mark W. Wade, Martin Stevens, Shellee D. Dyer, Xiaoge Zeng, Fabio Pavanello, Thomas Gerrits, Sae Woo Nam, Richard Mirin, Milos A. Popovic
Correlated photon pairs are a fundamental component of quantum photonic systems. While pair sources have previously been integrated on silicon chips in custom facilities, these often take advantage of only a small fraction of microelectronics fabrication

A near-infrared 64-pixel superconducting nanowire single photon detector array with integrated multiplexed readout

Michael S. Allman, Varun B. Verma, Martin J. Stevens, Thomas Gerrits, Robert D. Horansky, Adriana E. Lita, Francesco Marsili, A. Beyer, Matthew Shaw, D. Kumor, Richard P. Mirin, Sae Woo Nam
We demonstrate a 64-pixel free-space-coupled array of superconducting nanowire single photon detectors optimized for high detection efficiency in the near-infrared range. An integrated, readily scalable, multiplexed readout scheme is employed to reduce the

Varun B. Verma, Boris Korzh, Felix Bussieres, Robert D. Horansky, Shellee D. Dyer, Adriana E. Lita, Igor Vayshenker, Francesco Marsili, Matthew D. Shaw, Hugo Zbinden, Richard P. Mirin, Sae Woo Nam
We demonstrate high-efficiency superconducting nanowire single-photon detectors (SNSPDs) fabricated from MoSi thin-films. We measure a maximum system detection efficiency (SDE) of 87 ± 0.5 % at 1542 nm at a temperature of 0.7 K, with a jitter of 76 ps

Photon-efficient high-dimensional quantum key distribution

Tian Zhong, Hongchao Zhou, Rob Horansky, Catherine Lee, Varun Verma, Adriana Lita, Alessandro Restelli, Joshua Bienfang, Richard Mirin, Thomas Gerrits, Sae Woo Nam, Francesco Marsili, Zhenshen Zhang, Ligong Wang, Dirk Englund, Gregory Wornell, Jeffrey Shapiro, Franco N. Wong
Quantum key distribution (QKD) is a secure communication technology whose security is guaranteed by the laws of physics. However, its widespread use has been hindered in part by low secure-key throughput due to the inherent loss and de-coherence of photons

Spectral Correlation Measurements at the Hong-Ou-Mandel Interference Dip

Thomas Gerrits, Francesco Marsili, Varun B. Verma, Lynden K. Shalm, Jeffrey A. Stern, Matthew Shaw, Richard P. Mirin, Sae Woo Nam
We present an efficient tool capable of measuring the spectral correlations between photons emerging from a Hong-Ou-Mandel interference configuration. We show that the Hong-Ou-Mandel interference visibility decreases as the photons’ frequency spread is
