Experimental demonstration of scalable cross-entropy benchmarking to detect measurement-induced phase transitions on a superconducting quantum processor

Posted by dbos UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Hirsh Kamakari, Jiace Sun, Yaodong Li, Jonathan J. Thio, Tanvi P. Gujarati | Summary: Quantum systems subject to random unitary evolution and measurements at random points in spacetime exhibit entanglement phase transitions which depend on the frequency of these measurements. Past work has experimentally observed […]

Signatures of tidal disruption of the Hercules ultra-faint dwarf galaxy

Posted by dbos MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anirudh Chiti, Nora Shipp, Joshua D. Simon, Marla Geha | Summary: The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in identifying Hercules member stars. In […]

Dichotomous Dynamics of Magnetic Monopole Fluids

Posted by dbos Cornell

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Chun-Chih Hsu, Hiroto Takahashi, Fabian Jerzembeck, Jahnatta Dasini, Chaia Carroll | Summary: A recent advance in the study of emergent magnetic monopoles was the discovery that monopole motion is restricted to dynamical fractal trajectories (J. Hall’en et al, Science 378, 1218 (2022)) thus explaining the […]

Reducing the error rate of a superconducting logical qubit using analog readout information

Posted by dbos Delft

Kavli Affiliate: Leonardo Dicarlo | First 5 Authors: Hany Ali, Jorge Marques, Ophelia Crawford, Joonas Majaniemi, Marc Serra-Peralta | Summary: Quantum error correction enables the preservation of logical qubits with a lower logical error rate than the physical error rate, with performance depending on the decoding method. Traditional error decoding approaches, relying on the binarization […]

New probe of non-Gaussianities with primordial black hole induced gravitational waves

Posted by dbos Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma, Yi-Fu Cai, Emmanuel N. Saridakis | Summary: We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light ($M_{text{PBH}}< 10^{9}rm{g}$) primordial black holes (PBHs). Interestingly enough, the existence of primordial NG can leave […]

VisRec: A Semi-Supervised Approach to Radio Interferometric Data Reconstruction

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Haitao Wang, Qiong Luo, Feng Wang, Hejun Wu | Summary: Radio telescopes produce visibility data about celestial objects, but these data are sparse and noisy. As a result, images created on raw visibility data are of low quality. Recent studies have used deep learning models […]

Observational Evidence for Hot Wind Impact on pc-scale in Low-luminosity Active Galactic Nucleus

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Zhiyuan Li, Zhao Su, Suoqing Ji | Summary: Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow have the potential to play an important role […]
