$\mathcal{P}\mathcal{T}$-symmetric theory is developed to extend quantum mechanics a complex region, but it wins its great success first in classical systems, for example, optical waveguides and electric circuits, etc., because there are so many counterintuitive phenomena striking applications, including unidirectional light transport, $\mathcal{P}\mathcal{T}$-enhanced sensors (one kind of exceptional-point-based sensor), wireless power transfer. However, these applications mostly based on...
The initialization of a quantum system into certain state is crucial aspect information science. While variety measurement strategies have been developed to characterize how well the initialized, for given one, there in general trade-off between its efficiency and accessible state. Conventional tomography can unknown states while requiring exponentially expensive time-consuming postprocessing. Alternatively, recent theoretical breakthroughs show that verification provides technique quantify...
Isoscalar dipole transitions are a distinctive fingerprint of cluster structures. A 1^{-} resonance at 7.27(10) MeV, located just below the α-emission threshold, has been observed in deuteron inelastic scattering reactions off ^{10}Be. The deformation lengths excited states ^{10}Be 9 MeV have inferred from differential cross sections using coupled channel calculations. This isoscalar characteristics and exhausts approximately 5%-15% energy-weighted sum rule, providing evidence for pronounced...

However, practical constraints prevent the arbitrary of due imperfections a detector, especially when detector response is dominated by saturation effect. this work, we show that modified weak protocol, namely, biased significantly improves precision metrology presence This method detects an ultra-small fraction photons...
We have investigated the three-body force (TBF) effect on neutron and proton momentum distributions in asymmetric nuclear matter within framework of extended Brueckner-Hartree-Fock approach by adopting $AV18$ two-body interaction plus a microscopic TBF. In matter, it is shown that become different from their common distribution symmetric matter. The predicted depletion hole states increases while one decreases as function isospin asymmetry. TBF turns out to be negligibly weak at low...
Quantum metrology aims to enhance the precision of various measurement tasks by taking advantages quantum properties. In many scenarios, is not sole target; acquired information must be protected once it generated in sensing process. Considering a remote scenario where local site performs cooperative with collect sensitive at site, loss data inevitably causes revealed. key distribution known reliable solution for secure transmission; however, fails if an eavesdropper accesses site. this...

Instead preparing tensor product two singlets with four photons, multiplex encoding...
Self-testing is a method with which classical user can certify the state and measurements of quantum systems in device-independent way. In particular, self-testing entangled states great importance information processing. An understandable example that maximal violation Clauser-Horne-Shimony-Holt inequality necessarily implies bipartite system shares singlet. One essential question that, when one observes nonmaximum violation, how far tested from target (which maximally violates certain Bell...
Abstract Quantum entanglement is the key resource for quantum information processing. Device-independent certification of entangled states a long standing open question, which arouses concept self-testing. The central aim self-testing to certify state and measurements systems without any knowledge their inner workings, even when used devices cannot be trusted. Specifically, utilizing Bell’s theorem, one can infer appearance certain maximum violation observed, e.g., self-test singlet using...
Quantum entanglement, has been acknowledged as a precious resource due to its inherent nonclassical correlations between subsystems. These quantum have the potential for many processes, including canonical ones: cryptography, teleportation, and dense coding. To exploit advantages of two essential premises are required, i.e., prepare high-quality entanglement characterize quality level prepared entanglement. Thus far, can be produced in various systems; however, it appears that this new is...

We consider the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state with an angle dependent-gap (ADG) for arbitrary \theta_0 between direction of Cooper pair momentum and symmetry axis ADG in asymmetric nuclear matter. find two kinds locally stable states, i.e., FFLO-ADG-orthogonal FFLO-ADG-parallel which correspond to \theta_0=\pi/2 \theta_0=0, respectively. Furthermore, the-FFLO-ADG-orthogonal is located at small asymmetry, whereas favored large asymmetry. The critical isospin asymmetry...
