Roles of non-local electron-phonon coupling on the electrical conductivity and Seebeck coefficient: a TD-DMRG study
Yufei Ge, Weitang Li, Jiajun Ren +1
Organic molecular materials are potential high-performance thermoelectric materials. Theoretical understanding of thermoelectric conversion in organic materials is essential for ra…
Demonstration of a quantum logic gate in a cryogenic surface-electrode ion trap
Shannon X. Wang, Jaroslaw Labaziewicz, Yufei Ge +2
We demonstrate quantum control techniques for a single trapped ion in a cryogenic, surface-electrode trap. A narrow optical transition of Sr+ along with the ground and first excite…
Laser-induced charging of microfabricated ion traps
Shannon X. Wang, Guang Hao Low, Nathan S. Lachenmyer +3
Electrical charging of metal surfaces due to photoelectric generation of carriers is of concern in trapped ion quantum computation systems, due to the high sensitivity of the ions'…
One-dimensional array of ion chains coupled to an optical cavity
Marko Cetina, Alexei Bylinskii, Leon Karpa +7
We present a novel hybrid system where an optical cavity is integrated with a microfabricated planar-electrode ion trap. The trap electrodes produce a tunable periodic potential al…
Individual addressing of ions using magnetic field gradients in a surface-electrode ion trap
Shannon X. Wang, Jaroslaw Labaziewicz, Yufei Ge +2
Dense array of ions in microfabricated traps represent one possible way to scale up ion trap quantum computing. The ability to address individual ions is an important component of…
Learning from Multiple Annotators by Incorporating Instance Features
Jingzheng Li, Hailong Sun, Jiyi Li +3
Learning from multiple annotators aims to induce a high-quality classifier from training instances, where each of them is associated with a set of possibly noisy labels provided by…
