Multiphoton quantum metrology with neither pre- nor post-selected measurements

October 21, 2021
Author(s)
Chenglong You, Mingyuan Hong, Peter Bierhorst, Adriana Lita, Scott Glancy, Steven Kolthammer, Emanuel Knill, Sae Woo Nam, Richard Mirin, Omar Magana-Loaiza, Thomas Gerrits
The quantum statistical fluctuations of the electromagnetic field establish fundamental limits on the sensitivity of optical measurements. This fundamental limit, known as the shot-noise limit, imposes constraints on classical technologies, which can be

Improved shadow correction for the Marine Optical BuoY, MOBY

October 11, 2021
Author(s)
Kenneth Voss, Edouard Leymarie, Stephanie Flora, B. Carol Johnson, Arthur Gleason, Mark Yarbrough, Michael Feinholz, Terrance Houlihan
A 3-D instrument self-shading correction has been developed for the MOBY upwelling radiance measurements. This correction was tested using the 23 year time series of MOBY measurements, at the Lanai, Hawaii site. The correction is small (less than 2%)

Quantum-Based Photonic Sensors for Pressure, Vacuum, and Temperature Measurements: A Vison of the Future with NIST on a Chip

September 17, 2021
Author(s)
Jay H. Hendricks, Zeeshan Ahmed, Daniel Barker, Kevin O. Douglass, Stephen Eckel, James A. Fedchak, Nikolai Klimov, Jacob Edmond Ricker, Julia Scherschligt
The NIST on a Chip (NOAC) program's central idea is the idea that measurement technology can be developed to enable metrology to be performed "outside the National Metrology Institute" by the crea-tion of deployed and often miniaturized standards. These

Experimental confirmation of long hyperbolic polariton lifetimes in monoisotopic (10B) hexagonal boron nitride at room temperature

September 14, 2021
Author(s)
Georges Pavlidis, Jeffrey Schwartz, Joseph Matson, Thomas Folland, Song Liu, James Edgar, Joshua Caldwell, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs) enable arbitrarily high confinements, low losses, and directional propagation – providing opportunities from hyperlensing to flat optics, and other advanced nanophotonics applications. In this work, two near-field

Single-photon detection in the mid-infrared up to 10 micron wavelength using tungsten silicide superconducting nanowire detectors

September 14, 2021

Varun Verma, Adriana Lita, Yao Zhai, Heli C. Vora, Richard Mirin, Sae Woo Nam, Boris Korzh, Alex Walter, Ryan Briggs, Marco Colangelo, Emma Wollman, Andrew Beyer, Jason Allmaras, D. Zhu, Ekkehart Schmidt, A. G. Kozorezov, Matthew Shaw
We developed superconducting nanowire single-photon detectors (SNSPDs) based on tungsten silicide (WSi) that show saturated internal detection efficiency up to a wavelength of 10 um. These detectors are promising for applications in the mid-infrared

Ultraviolet Radiation Technologies and Healthcare Associated Infections: Standards and Metrology Needs

August 20, 2021
Author(s)
Dianne L. Poster, C Cameron Miller, Richard Martinello, Norman Horn, Michael T. Postek, Troy Cowan, Yaw S. Obeng, John J. Kasianowicz
The National Institute of Standards and Technology (NIST) hosted an international workshop on ultraviolet-C (UV-C) disinfection technologies on January 14 – 15, 2020 in Gaithersburg, Maryland in collaboration with the International Ultraviolet Association

Topological Frequency Combs and Nested Temporal Solitons

August 5, 2021

Sunil Mittal, Gregory Moille, Kartik Srinivasan, Yanne Chembo, Mohammad Hafezi
Recent advances in realizing optical frequency combs using nonlinear parametric processes in integrated photonic resonators have revolutionized on-chip optical clocks, spectroscopy, and multi channel optical communications. At the same time, the

We demonstrate the integration of amorphous tungsten silicide superconducting nanowire single- photon detectors on titanium in-diffused lithium niobate waveguides. We show proof-of-principle detection of evanescently-coupled photons of wavelength 1550nm

Single-cycle all-fiber frequency comb

Sida Xing, Daniel Lesko, Takeshi Umeki, Tsung Han Wu, Alexander Lind, Nazanin Hoghooghi, Scott Diddams
Broad bandwidth mid-infrared frequency combs are important for molecular spectroscopy in a wide range of fundamental and applied research. However, realization of such light sources in a compact and robust format remains a challenge. In this paper, we

Overcoming thermo-optical dynamics in broadband nanophotonic sensing

July 7, 2021

Mingkang Wang, Diego J. Perez, Vladimir Aksyuk
Advances in integrated photonics open exciting opportunities for batch-fabricated optical nano- electro-mechanical sensors with ultra-high sensitivities and bandwidths enabled by cavity optomechanics. However, heat from the amplified optical intensity

Machine-learning enhanced dark soliton detection in Bose-Einstein condensates

June 15, 2021
Author(s)
Shangjie Guo, Amilson R. Fritsch, Ian Spielman, Justyna Zwolak
Most data in cold-atom experiments comes from images, the analysis of which is limited by our preconceptions of the patterns that could be present in the data. We focus on the well-defined case of detecting dark solitons—appearing as local density

Witnessing the survival of time-energy entanglement through biological tissue and media

June 9, 2021
Author(s)
Daniel J. Lum, Michael Mazurek, Alexander Mikhaylov, Kristen M. Parzuchowski, Ryan M. Wilson, Marcus Cicerone, Ralph Jimenez, Thomas Gerrits, Martin Stevens, Charles Camp
In this work, we demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media ( 1.55 mm) and tissue ( 235 um) at room temperature. Using a Franson-type interferometer, we demonstrate interferometric contrast of

High-performance semiconductor quantum dot-single- photon sources

Glenn S. Solomon
Single photons are a key, fundamental element of most quantum optical technologies, be it for the development of large-scale quantum communication networks, for quantum simulation, or for connecting quantum memories in a quantum computer. The ideal single

Topological insulators could profoundly impact the fields of spintronics, quantum computing and low-power electronics. To enable investigations of these non-trivial phases of matter beyond the reach of present-day experiments, quantum simulations provide

Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal
