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

June 3, 2021
Author(s)
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

Photonic quantum simulations of SSH-type topological insulators with perfect state transfer

Author(s)
Thomas Gerrits, Sae Woo Nam, Adriana Lita, M. Stobinska, T Sturges, A. Buraczewski, W.R. Clements, Jelmer J. Renema, Ian Walmsley
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

Author(s)
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

May 26, 2021
Author(s)
Ashutosh Rao, Gregory Moille, Xiyuan Lu, Daron Westly, Davide Sacchetto, Michael Geiselmann, Michael Zervas, Scott Papp, John E. Bowers, Kartik Srinivasan
Microcombs - optical frequency combs generated in microresonators - have advanced tremendously in the last decade, and are advantageous for applications in frequency metrology, navigation, spectroscopy, telecommunications, and microwave photonics

Portable bioluminescent platform for in vivo monitoring of biological processes in non-transgenic animals

May 11, 2021

Aleksey Yevtodiyenko, Arkadiy Bazhin, Pavlo Khodakivskyi, Aurelien Godinat, Gyslain Budin, Marina Kunchulia, Giorgio Pietramaggiori, Sandra Scherer, Elena Goun, Sergey Polyakov, George P. Eppeldauer
Bioluminescent imaging (BLI) is one of the most powerful and widely used preclinical imaging modalities. However, the current technology relies on the use of transgenic luciferase-expressing cells and animals and therefore can only be applied to a limited

Optoelectronic Intelligence

May 7, 2021
Author(s)
Jeff Shainline
To design and construct hardware for general intelligence, we must consider principles of both neuroscience and very-large-scale integration. For large neural systems capable of general intelligence, the attributes of photonics for communication and

Vectorizing Green's Identities

May 5, 2021
Author(s)
Alex Yuffa
Green's theorem and Green's identities are well-known and their uses span almost every branch of science and mathematics. In this paper, we derive a vector analogue of Green's three scalar identities and consider some of their uses. We also offer a number

Edward Garboczi, Ann Debay, Somen Baidya, Ahmed M. Hassan, Andrew Sharits, Jay D. Goguen, Thomas Lafarge, Mikolas Melius
Shape is a critical property, besides size and material composition, which has a strong effect on the optical scattering characteristics of a particle. In this work, we computationally study how the measured three-dimensional shapes of lunar regolith
