Experimental Demonstration of a Measurement-Feedback Quantum Information Engine
Jinfeng Wei, Yingying Hong, Dehua Liu +8
Harnessing finite-time nonadiabatic transitions that are conventionally associated with quantum inner friction for useful work extraction remains an open experimental challenge. He…
Enhancing Nonreciprocity through Squeezing-Induced Symmetry Breaking
B. -B. Liu, D. -Y. Wang, J. Tang +4
Reservoir engineering enables unidirectional energy and signal flow. We establish squeezing-induced symmetry breaking between two cavities as a guiding principle for exponentially…
Connection-topology--dependent energy transport and ergotropy in quantum battery networks with reciprocal and nonreciprocal couplings
Bing-Bing Liu, Rui Chen, Jin-Lei Wu +2
The realization of scalable quantum battery architectures requires concern not only with how much energy can be stored, but also with how energy is transported, distributed, and co…
Time Crystal in the Nonlinear Phonon Mode of the Trapped Ions
Yi-Ling Zhan, Chun-Fu Liu, J. -T. Bu +4
Time crystals constitute a novel phase of matter defined by the spontaneous breaking of timetranslation symmetry. Here we present a scheme to realize a continuous-time crystal of t…
Beyond the Carnot Limit in the Internal Cycles of a Quantum Heat Engine under Finite Heat Reservoirs
L. -L. Yan, M. -R. Yun, M. Li +4
We investigate, in an analytical fashion, quantum Carnot cycles of a microscopic heat engine coupled to two nite heat reservoirs, whose internal cycles could own higher e ciency th…
Experimental Verification of Demon-Involved Fluctuation Theorems
L. -L. Yan, J. -T. Bu, Q. Zeng +8
The limit of energy saving in the control of small systems has recently attracted much interest due to the concept refinement of the Maxwell demon. Inspired by a newly proposed set…
Precision measurement for open systems by non-hermitian linear response
Peng Xu, Gang Chen
The lower bound of estimated precision for a coherent parameter unitarily encoded in closed systems has been obtained, and such a lower bound is inversely proportional to the fluct…
One-step implementation of nonadiabatic geometric fSim gate in superconducting circuits
M. -R. Yun, Zheng Shan, Li-Li Sun +3
Due to its significant application in reducing algorithm depth, fSim gates have attracted a lot of attention. However, during the implementation of quantum gates, fluctuations in c…
