A Logarithmic Bayesian Approach to Quantum Error Detection

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, K. Birgitta Whaley, , , | Summary: We consider the problem of continuous quantum error correction from a Bayesian perspective, proposing a pair of digital filters using logarithmic probabilities that are able to achieve near-optimal performance on a three-qubit bit-flip code while still being […]

Lattice Simulations of Abelian Gauge Fields coupled to Axion during Inflation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We use a non-linear lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. This kind of models have already been studied with a […]

Rapid growth of seed black holes during early bulge formation

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Riouhei Nakatani, Daisuke Toyouchi, Takashi Hosokawa, Rolf Kuiper | Summary: We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where the stellar bulge component is assembled, performing axisymmetric two-dimensional radiation hydrodynamical simulations. We find that when a seed […]

Machine Learning for Continuous Quantum Error Correction on Superconducting Qubits

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, Haoran Liao, Song Zhang, Sahil Patel, William P. Livingston | Summary: We propose a machine learning algorithm for continuous quantum error correction that is based on the use of a recurrent neural network to identity bit-flip errors from continuous noisy syndrome measurements. The algorithm […]

TOI-2285b: A 1.7 Earth-radius Planet Near the Habitable Zone around a Nearby M Dwarf

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Akihiko Fukui, Tadahiro Kimura, Teruyuki Hirano, Norio Narita, Takanori Kodama | Summary: We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the Transiting Exoplanet Survey Satellite photometric data, […]

Precision analysis of the redshift-space galaxy bispectrum

Kavli Affiliate: Masahiro Takada | First 5 Authors: Mikhail M. Ivanov, Oliver H. E. Philcox, Takahiro Nishimichi, Marko Simonović, Masahiro Takada | Summary: We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbation theory model that includes galaxy […]

Momentum deposition of supernovae with cosmic rays

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Debora Sijacki, Adrianne Slyz, Julien Devriendt | Summary: The cataclysmic explosions of massive stars as supernovae are one of the key ingredients of galaxy formation. However, their evolution is not well understood in the presence of magnetic fields or cosmic rays (CRs). […]
