Exceptional points (EPs) of a non-Hermitian Hamiltonian with parity-time-reversal $(\mathcal{P}\mathcal{T})$ symmetry have the potential to drastically enhance capabilities metrology and sensing through their power-law growing sensitivity external perturbation. With ability generating tuning dissipation in single trapped ion system, we observe rich dynamics detailed quantum phase transitions from $\mathcal{P}\mathcal{T}$-symmetric symmetry-breaking phase. In this qubit full develop method...
Non-Hermitian systems with parity-time reversal ($\mathcal{PT}$) or anti-$\mathcal{PT}$ symmetry have attracted a wide range of interest owing to their unique characteristics and counterintuitive phenomena. One the most extraordinary features is presence an exception point (EP), across which phase transition spontaneously broken $\mathcal{PT}$ takes place. We implement Floquet Hamiltonian single qubit by periodically driving dissipative quantum system trapped ion. With stroboscopic emission...

Recently, anomalous Floquet topological phases without static counterparts have been observed in different systems, where periodically driven models are realized to support a winding number of 1 and pair edge modes each quasienergy gap. Here, we focus on cold atomic gases optical lattices propose novel driving scheme that breaks rotation symmetry but maintains inversion the instantaneous Hamiltonian, discover type phase with larger than 1. By analyzing condition band touching under...
Exploring quantum phenomena beyond predictions of any classical model has fundamental importance to understand the boundary and descriptions nature. As a typical property that system behaves distinctively from counterpart, contextuality been studied extensively verified experimentally in systems composed at least three levels (qutrit). Here we extend scope experimental test minimal only two states (qubit) by implementing minimum error state discrimination on single $^{171}$Yb$^+$ ion. We...
The completely integrable Hamiltonian systems have been applied to physics and mechanics intensively. We generate a family of from some kinds exact Poisson structures in 3 by the realization algebra. Moreover, we prove that there is algebra which cannot be realized an structure.
As an essential concept to understand the world, whether real values (or physical realities) of observables are suitable systems beyond classic has been debated for many decades. Although standard no-go results based on Bell inequalities have ruled out joint reality incompatible quantum observables, possibility giving simple yet strong arguments rule in any system (not necessarily quantum) with weaker assumptions and less explored proposed recently. Here, we perform a device-independent...
Whether the observables of a physical system admit real values is fundamental importance to deep understanding nature. In this work, we report device-independent experiment confirm that joint reality two on single two-level incompatible with assumption operational completeness, which strictly weaker than preparation noncontextuality. We implement trapped $^{171}{\rm Yb}^{+}$ ion test incompatibility via violation certain inequalities derived from both linear and nonlinear criteria. Moreover,...
