Baseband control of single-electron silicon spin qubits in two dimensions

Posted by dbos Delft, This Week: Nanoscience

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Florian K. Unseld, Brennan Undseth, Eline Raymenants, Yuta Matsumoto, Saurabh Karwal | Summary: Micromagnet-enabled electric-dipole spin resonance (EDSR) is an established method of high-fidelity single-spin control in silicon. However, the resulting architectural limitations have restrained silicon quantum processors to one-dimensional arrays, and heating effects from the associated […]

Towards Flexible 3D Perception: Object-Centric Occupancy Completion Augments 3D Object Detection

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Feng Wang | First 5 Authors: Chaoda Zheng, Feng Wang, Naiyan Wang, Shuguang Cui, Zhen Li | Summary: While 3D object bounding box (bbox) representation has been widely used in autonomous driving perception, it lacks the ability to capture the precise details of an object’s intrinsic geometry. Recently, occupancy has emerged as a […]

EvTTC: An Event Camera Dataset for Time-to-Collision Estimation

Posted by dbos This Week: Theoretical Physics, UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Kaizhen Sun, Jinghang Li, Kuan Dai, Bangyan Liao, Wei Xiong | Summary: Time-to-Collision (TTC) estimation lies in the core of the forward collision warning (FCW) functionality, which is key to all Automatic Emergency Braking (AEB) systems. Although the success of solutions using frame-based cameras (e.g., Mobileye’s solutions) […]

Origin of Increased Curie Temperature in Lithium-Substituted Ferroelectric Niobate Perovskite: Enhancement of the Soft Polar Mode

Posted by dbos Peking, This Week: Astrophysics

Kavli Affiliate: Ke Wang | First 5 Authors: Hao-Cheng Thong, Fang-Zhou Yao, Xian-Xian Cai, Ze Xu, Mao-Hua Zhang | Summary: The functionality of ferroelectrics is often constrained by their Curie temperature, above which depolarization occurs. Lithium (Li) is the only experimentally known substitute that can increase the Curie temperature in ferroelectric niobate-based perovskites, yet the […]
