Optical Investigations of Coherence and Relaxation Dynamics of a Thulium-doped Yttrium Gallium Garnet Crystal at sub-Kelvin Temperatures for Optical Quantum Memory

Posted by dbos Delft

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Antariksha Das, Mohsen Falamarzi Askarani, Jacob H. Davidson, Neil Sinclair, Joshua A. Slater | Summary: Rare-earth ion-doped crystals are of great interest for quantum memories, a central component in future quantum repeaters. To assess the promise of 1$%$ Tm$^{3+}$-doped yttrium gallium garnet (Tm:YGG), we report measurements of […]

The Size-luminosity Relation of the AGN Torus Determined from the Comparison between Optical and Mid-infrared Variability

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Minjin Kim, Suyeon Son, Luis C. Ho, , | Summary: We investigate the optical variability of low-redshift ($0.15< zleq0.4$) active galactic nuclei using the multi-epoch data from the Zwicky Transient Facility. We find that a damped random walk model well describes the ensemble structure function in […]

Coherent Erbium Spin Defects in Colloidal Nanocrystal Hosts

Posted by dbos Berkeley

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Joeson Wong, Mykyta Onizhuk, Jonah Nagura, Arashdeep S. Thind, Jasleen K. Bindra | Summary: We demonstrate nearly a microsecond of spin coherence in Er3+ ions doped in cerium dioxide nanocrystal hosts, despite a large gyromagnetic ratio and nanometric proximity of the spin defect to the nanocrystal surface. […]

SSNVC: Single Stream Neural Video Compression with Implicit Temporal Information

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Haihang Ruan, Zhihuang Xie, Ronggang Wang, Xiangyu Yue | Summary: Recently, Neural Video Compression (NVC) techniques have achieved remarkable performance, even surpassing the best traditional lossy video codec. However, most existing NVC methods heavily rely on transmitting Motion Vector (MV) to generate accurate contextual features, […]

High-fidelity single-spin shuttling in silicon

Posted by dbos Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Maxim De Smet, Yuta Matsumoto, Anne-Marije J. Zwerver, Larysa Tryputen, Sander L. de Snoo | Summary: The computational power and fault-tolerance of future large-scale quantum processors derive in large part from the connectivity between the qubits. One approach to increase connectivity is to engineer qubit-qubit interactions at […]

EFFOcc: A Minimal Baseline for EFficient Fusion-based 3D Occupancy Network

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yining Shi, Kun Jiang, Ke Wang, Kangan Qian, Yunlong Wang | Summary: 3D occupancy prediction (Occ) is a rapidly rising challenging perception task in the field of autonomous driving which represents the driving scene as uniformly partitioned 3D voxel grids with semantics. Compared to 3D object detection, […]
