Dynamical Control of Quantum Heat Engines Using Exceptional Points
J. -W. Zhang, J. -Q. Zhang, G. -Y. Ding +11
A quantum thermal machine is an open quantum system coupled to hot and cold thermal baths. Thus, its dynamics can be well understood using the concepts and tools from non-Hermitian…
Single-atom verification of the noise-resilient and fast characteristics of universal nonadiabatic noncyclic geometric quantum gates
J. W. Zhang, L. -L. Yan, J. C. Li +6
Quantum gates induced by geometric phases are intrinsically robust against noise due to their global properties of the evolution paths. Compared to conventional nonadiabatic geomet…
Single-Atom Verification of the Information-Theoretical Bound of Irreversibility at the Quantum Level
J. W. Zhang, K. Rehan, M. Li +6
Quantitative measure of disorder or randomness based on the entropy production characterizes thermodynamical irreversibility, which is relevant to the conventional second law of th…
Single-qubit measurement of Heisenberg uncertainty lower bounds for three incompatible observables
K. Rehan, T. P. Xiong, L. -L. Yan +6
Being one of the centroidal concepts in quantum theory, the fundamental constraint imposed by Heisenberg uncertainty relations has always been a subject of immense attention and ch…
Ion-crystal demonstration of structural phase transition induced solely by temperature
J. Li, L. L. Yan, L. Chen +5
We demonstrate for the first time a linear-zigzag phase transition induced solely by temperature of the Ca ion crystals in a surface-electrode trap. In contrast to the…
Experimental verification of a Jarzynski-related information-theoretic equality using a single trapped ion
T. P. Xiong, L. L. Yan, F. Zhou +7
Most non-equilibrium processes in thermodynamics are quantified only by inequalities, however the Jarzynski relation presents a remarkably simple and general equality relating non-…
