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-…
Optimal joint measurements of complementary observables by a single trapped ion
T. P. Xiong, L. L. Yan, Z. H. Ma +5
The uncertainty relations, pioneered by Werner Heisenberg nearly 90 years ago, set a fundamental limitation on the joint measurability of complementary observables. This limitation…
Mechanism for quantum speedup in open quantum systems
Hai-Bin Liu, W. L. Yang, Jun-Hong An +1
The quantum speed limit (QSL) time for open system characterizes the most efficient response of the system to the environmental influences. Previous results showed that the non-Mar…
Realizing Topological Transition in a Non-Hermitian Quantum Walk with Circuit QED
Yizhou Huang, Zhang-qi Yin, W. L. Yang
We extend the non-Hermitian one-dimensional quantum walk model [Phys. Rev. Lett. 102, 065703 (2009)] by taking the dephasing effect into account. We prove that the feature of topol…
Phonon induced two-mode squeezing of nitrogen-vacancy center ensembles
Qidong Xu, W. L. Yang, Zhang-qi Yin
We propose a potentially practical scheme for realization of two-mode squeezed state with respect to two distant nitrogen-vacancy center ensembles coupled to two interconnected mec…
Exploring the quantum critical behaviour in a driven Tavis-Cummings circuit
M. Feng, Y. P. Zhong, T. Liu +4
Quantum phase transitions play an important role in many-body systems and have been a research focus in conventional condensed matter physics over the past few decades. Artificial…
