Long-Range QKD without Trusted Nodes is Not Possible with Current Technology

Posted by dbos Delft

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Bruno Huttner, Romain Alléaume, Eleni Diamanti, Florian Fröwis, Philippe Grangier | Summary: A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to achieve long-range quantum security without trusted nodes and without use of quantum repeaters. Here we present a […]

Gas Morphology of Milky Way-like Galaxies in the TNG50 Simulation: Signals of Twisting and Stretching

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Thomas K. Waters, Colton Peterson, Razieh Emami, Xuejian Shen, Lars Hernquist | Summary: We present an in-depth analysis of gas morphologies for a sample of 25 Milky Way-like galaxies from the IllustrisTNG TNG50 simulation. We constrain the morphology of cold, warm, hot gas, and gas particles as […]

Revealing AGNs Through TESS Variability

Posted by dbos MIT

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh, Benjamin J. Shappee, Christopher S. Kochanek | Summary: We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision TESS light curves present a unique […]

TESS spots a mini-neptune interior to a hot saturn in the TOI-2000 system

Posted by dbos MIT

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang, David J. Armstrong, Rafael Brahm | Summary: Hot jupiters (P < 10 d, M > 60 $mathrm{M}_oplus$) are almost always found alone around their stars, but four out of hundreds known have inner companion planets. These rare companions […]

Superfluid response of an atomically thin, gate-tuned van der Waals superconductor

Posted by dbos Cornell

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Alexander Jarjour, G. M. Ferguson, Brian T. Schaefer, Menyoung Lee, Yen Lee Loh | Summary: A growing number of two-dimensional superconductors are being discovered in the family of layered van der Waals (vdW) materials. Due to small sample volume, their characterization has been largely limited to […]

A primordial atmospheric origin of hydrospheric deuterium enrichment on Mars

Posted by dbos Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Kaveh Pahlevan, Laura Schaefer, Linda T. Elkins-Tanton, Steven J. Desch, Peter R. Buseck | Summary: The deuterium-to-hydrogen (D/H or 2H/1H) ratio of Martian atmospheric water (~6x standard mean ocean water, SMOW) is higher than that of known sources, requiring planetary enrichment. A recent measurement by NASA’s Mars […]
