Symmetrically Threaded SQUIDs As Next Generation Kerr-cat Qubits

Kavli Affiliate: Ke Wang | First 5 Authors: Bibek Bhandari, Irwin Huang, Ahmed Hajr, Kagan Yanik, Bingcheng Qing | Summary: Kerr-cat qubits are bosonic qubits with autonomous protection against bit-flips. They have been studied widely using driven Superconducting Nonlinear Asymmetric Inductive eLement (SNAIL) oscillators. We theoretically investigate an alternate circuit for the Kerr-cat qubit, namely […]

Constraining possible $γ$-ray burst emission from GW230529 using Swift-BAT and Fermi-GBM

Kavli Affiliate: Lijing Shao | First 5 Authors: Samuele Ronchini, Suman Bala, Joshua Wood, James Delaunay, Simone Dichiara | Summary: GW230529 is the first compact binary coalescence detected by the LIGO-Virgo-KAGRA collaboration with at least one component mass confidently in the lower mass-gap, corresponding to the range 3-5$M_{odot}$. If interpreted as a neutron star-black hole […]

Localizing Task Information for Improved Model Merging and Compression

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Guillermo Ortiz-Jimenez, François Fleuret, Pascal Frossard | Summary: Model merging and task arithmetic have emerged as promising scalable approaches to merge multiple single-task checkpoints to one multi-task model, but their applicability is reduced by significant performance loss. Previous works have linked these drops […]
