Efficiently improving the performance of noisy quantum computers

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Samuele Ferracin, Akel Hashim, Jean-Loup Ville, Ravi Naik, Arnaud Carignan-Dugas | Summary: Using near-term quantum computers to achieve a quantum advantage requires efficient strategies to improve the performance of the noisy quantum devices presently available. We develop and experimentally validate two efficient error mitigation protocols named "Noiseless […]

The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Lily L. Zhao, Debra A. Fischer, Eric B. Ford, Alex Wise, Michaël Cretignier | Summary: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods […]

Accurate effective fluid approximation for ultralight axions

Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, , , | Summary: Ultralight axions are theoretically interesting and phenomenologically rich dark sector candidates, but they are difficult to track across cosmological timescales because of their fast oscillations. We resolve this problem by developing a novel method to evolve them efficiently and […]

ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions — VIII. A search for hot cores by using C$_2$H$_5$CN, CH$_3$OCHO and CH$_3$OH lines

Kavli Affiliate: Ke Wang | First 5 Authors: Sheng-Li Qin, Tie Liu, Xunchuan Liu, Paul F. Goldsmith, Di Li | Summary: Hot cores characterized by rich lines of complex organic molecules are considered as ideal sites for investigating the physical and chemical environments of massive star formation. We present a search for hot cores by […]
