Secret extraction attacks against obfuscated IQP circuits

Kavli Affiliate: David Gross | First 5 Authors: David Gross, Dominik Hangleiter, , , | Summary: Quantum computing devices can now perform sampling tasks which, according to complexity-theoretic and numerical evidence, are beyond the reach of classical computers. This raises the question of how one can efficiently verify that a quantum computer operating in this […]

Scaling analysis of two-dimensional random singlet state in magnetic field

Kavli Affiliate: Long Zhang | First 5 Authors: Chen Peng, Long Zhang, , , | Summary: Quenched randomness strongly affects properties of magnetic materials. Two-dimensional (2D) random singlet (RS) states emerge in random $J$-$Q$ model by destroying valence bond solid order with spatial randomness. We examine the 2D RS state in magnetic field with quantum […]

OGLE-BLAP-009 — A Case Study for the Properties and Evolution of Blue Large-Amplitude Pulsators

Kavli Affiliate: Lars Bildsten | First 5 Authors: Corey W. Bradshaw, Matti Dorsch, Thomas Kupfer, Brad N. Barlow, Uli Heber | Summary: Blue large-amplitude pulsators (BLAPs) make up a rare class of hot pulsating stars with effective temperatures of $approx$30,000 K and surface gravities of 4.0 – 5.0 dex (cgs). The evolutionary origin and current […]

Superconductivity and Competing Orders in the Square-Lattice $t$-$J$-$V$ Model: Insights into Electron-Doped Cuprates

Kavli Affiliate: Fuchun Zhang | First 5 Authors: Qianqian Chen, Lei Qiao, Fuchun Zhang, Zheng Zhu, | Summary: To understand the discrepancies between the experimental observations of the weak or absent superconductivity in electron-doped cuprates and the extraordinarily robust superconductivity in numerical results of the $t$-$J$-type model, we investigate the role of inter-site electron interactions […]
