Signatures of BH seeding on the $mathrm{M_{displaystyle bullet}}-σ$ relation: Predictions from the BRAHMA simulations

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jonathan Kho, Jonathan Kho, , , | Summary: The James Webb Space Telescope (JWST) has identified a large population of supermassive ($10^6$-$10^8~mathrmM_odot$) black holes (BHs) in the early universe ($z sim 4$-$7$). Current measurements suggest that many of these BHs exhibit higher BH-to-stellar mass ratios than local […]

Improving the lifetime of aluminum-based superconducting qubits through atomic layer etching and deposition

Posted by klaurent Caltech

Kavli Affiliate: Oskar Painter | First 5 Authors: Neha Mahuli, Neha Mahuli, , , | Summary: We present a dry surface treatment combining atomic layer etching and deposition (ALE and ALD) to mitigate dielectric loss in fully fabricated superconducting quantum devices formed from aluminum thin films on silicon. The treatment, performed as a final processing […]

Experimental realization of the bucket-brigade quantum random access memory

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Fanhao Shen, Yujie Ji, Debin Xiang, Yanzhe Wang, Ke Wang | Summary: Quantum random access memory (QRAM) enables efficient classical data access for quantum computers — a prerequisite for many quantum algorithms to achieve quantum speedup. Despite various proposals, the experimental realization of QRAM remains largely unexplored. […]

Extracting Multimodal Learngene in CLIP: Unveiling the Multimodal Generalizable Knowledge

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Ruiming Chen, Junming Yang, Shiyu Xia, Xu Yang, Jing Wang | Summary: CLIP (Contrastive Language-Image Pre-training) has attracted widespread attention for its multimodal generalizable knowledge, which is significant for downstream tasks. However, the computational overhead of a large number of parameters and large-scale pre-training poses challenges of […]

XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates

Posted by klaurent Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Eungkyun Kim, Eungkyun Kim, , , | Summary: AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effect transistors, analogous to silicon-on-insulator technology. Unlike SiO$_2$/Si/SiO$_2$, AlN/GaN/AlN can be grown […]
