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…

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…

Chiral quantum heating and cooling with an optically controlled ion
Jin-Tao Bu, Jian-Qi Zhang, Ge-Yi Ding +12
Quantum heat engines and refrigerators are open quantum systems, whose dynamics can be well understood using a non-Hermitian formalism. A prominent feature of non-Hermiticity is th…
