Experimental implementation of generalized transitionless quantum driving.
Chang-Kang Hu,Jin-Ming Cui,Alan C. Santos,Yun-Feng Huang,Marcelo S. Sarandy,Chuan-Feng Li,Guang-Can Guo +6 more
TL;DR: In this article, a generalized generalized TQD was proposed for transitionless quantum driving, which is expressed in terms of an arbitrary phase when mimicking the adiabatic evolution.
Journal ArticleDOI
Quantum thermodynamics in adiabatic open systems and its trapped-ion experimental realization
Chang-Kang Hu,Chang-Kang Hu,Alan C. Santos,Jin-Ming Cui,Yun-Feng Huang,Diogo O. Soares-Pinto,Marcelo S. Sarandy,Chuan-Feng Li,Guang-Can Guo +8 more
TL;DR: In this article, the authors derived the conditions that an adiabatic open-system quantum dynamics implies in the absence of heat exchange, and determined families of decohering systems exhibiting the same maximal heat exchange.
Journal ArticleDOI
Low-loss interconnects for modular superconducting quantum processors
Jin Niu,Libo Zhang,Yang Liu,Jiawei Qiu,Wenhui Huang,Jia-Xin Huang,Hao Jia,Jiawei Liu,Ziyu Tao,Weiwei Wei,Yuxuan Zhou,Wanjing Zou,Yuanzhen Chen,Xiaowei Deng,X. H. Deng,Chang-Kang Hu,Lingzhi Hu,Jian Li,D. Tan,Yuan Xu,Fei Yan,Tongxing Yan,Song Liu,Youpeng Zhong,Andrew Cleland,Dapeng Yu +25 more
TL;DR: In this article , the authors report low-loss interconnects based on pure aluminium coaxial cables and on-chip impedance transformers with quality factors up to $8.1 \times 10^5$, which is comparable to the performance of transmon qubits fabricated on a single-crystal sapphire substrate.
Journal ArticleDOI
Polarization nondegenerate fiber Fabry-Perot cavities with large tunable splittings
Jin-Ming Cui,Zhou Kun,Ming-Shu Zhao,Ming-Zhong Ai,Chang-Kang Hu,Qiang Li,Bi-Heng Liu,Jin-Lan Peng,Yun-Feng Huang,Chuan-Feng Li,Guang-Can Guo +10 more
TL;DR: In this paper, the authors demonstrate a type of microcavity with large tunable splitting of polarization modes, which consists of two ellipsoidal concave mirrors with controllable eccentricity by CO2 laser machining on fiber end facets.
