Single-atom sensor for low-frequency electric field
Quan Yuan, Shuang-Qing Dai, Tai-Hao Cui +8
Precision measurement of low-frequency electric field (LFEF) signals with frequency from 30 kHz to 300 kHz is crucial for advancing both fundamental science and practical applicati…
Enhanced detection of electric field signals via squeezing-induced stochastic resonance
Ya-Qi Wei, Tai-Hao Cui, Quan Yuan +10
Stochastic resonance (SR) could amplify weak electric-field signals in nonlinear systems by means of the externally injected noises. Here we propose and experimentally demonstrate…
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…
Detection of DC electric forces with zeptonewton sensitivity by single-ion phonon laser
Ya-Qi Wei, Ying-Zheng Wang, Zhi-Chao Liu +6
Detecting extremely small forces helps exploring new physics quantitatively. Here we demonstrate that the phonon laser made of a single trapped Ca ion behaves as an ex…
Phonon-laser ultrasensitive force sensor
Zhichao Liu, Yaqi Wei, Liang Chen +4
Developing nano-mechanical oscillators for ultrasensitive force detection is of great importance in exploring science. We report our achievement of ultrasensitive detection of the…
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-…
Reply to comment in arXiv:1802.01382
T. P. Xiong, L. L. Yan, F. Zhou +7
Here we respond to a comment [arXiv:1802.01382] submitted recently on 'Experimental Verification of a Jarzynski-Related Information-Theoretic Equality by a Single Trapped Ion' PRL…
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…
A complicated Duffing oscillator in the surface-electrode ion trap
Hao-Yu Wu, Yi. Xie, Wei Wan +3
The oscillation coupling and different nonlinear effects are observed in a single trapped ion confined in our home-built surface-electrode trap (SET). The coupling an…
Franck-Condon Physics in A Single Trapped Ion
Y. M. Hu, W. L. Yang, Y. Y. Xu +5
We propose how to explore the Franck-Condon (FC) physics via a single ion confined in a spin-dependent potential, formed by the combination of a Paul trap and a magnetic field grad…
Solution to Satisfiability problem by a complete Grover search with trapped ions
W. L. Yang, H. Wei, F. Zhou +2
The main idea in the original Grover search (Phys. Rev. Lett. 79, 325 (1997)) is to single out a target state containing the solution to a search problem by amplifying the amplitud…
