Antimicrobial peptides (AMPs) play pivotal roles in protecting against microbial infection fish. However, AMPs from topmouth culter ( Erythroculter ilishaeformis ) are rarely known. In our study, we isolated an AMP the head kidney of culter, which belonged to liver-expressed antimicrobial peptide 2 (LEAP-2) family. Topmouth LEAP-2 showed inhibitory effects on aquatic bacterial growth, including antibiotic-resistant bacteria, with minimal concentration values ranging 18.75 150 μg/ml. It was...
The theory of phase control coherence, entanglement and quantum steering is developed for an optomechanical system composed a single mode cavity containing partially transmitting dielectric membrane driven by short laser pulses. closed loop in the coupling creates interfering channels which depend on relative strengths field modes to mechanical mode. We show several interesting dependent effects such as reversible population transfer from one other, creation collective modes, induced...
Quantum coherence has wide-ranging applications from quantum thermodynamics to metrology, channel discrimination and even biology. Thus, detecting quantifying are two fundamental problems in resource theory. Here, we introduce feasible methods detect estimate the by constructing witnesses for any finite-dimensional states. Our coherent states testing whether expectation value of witness is negative or not. Two typical proposed discussed based on our witness-constructing method, which also...
Genuine multipartite entanglement has been found in some spin chain systems. However, genuine nonlocality is much rarer than entanglement. Here we present a system. After introducing the definition of and Bell-type inequality, construct group joint measurements for inequality one-dimensional ferromagnetic $N$-qubit with nearest-neighbor $XXZ$ interaction, many violations to have found. The do indicate that exists this spin-1/2 Last but not least, also calculate concurrence same demonstrate...
Experimentally quantifying entanglement and coherence is extremely important in quantum information processing. In a multipartite system, usually the fidelity of system's state compared to target measured detect its entanglement. The authors present fidelity-based method derive experimentally accessible lower bounds for measures genuine coherence, allowing quick quantification system states without tomography experiments. works generally, several measures, examples real experimental are...
Quantifying coherence and entanglement is extremely important in quantum information processing. Here, we present numerical analytical results for the geometric measure of coherence, also entanglement. On one hand, first provide a semidefinite algorithm to numerically calculate arbitrary finite-dimensional mixed states. Based on this algorithm, test randomly generated single-qubit states, single-qutrit special kind d-dimensional Moreover, obtain an solution other another proposed two-qubit...
We provide detailed proofs of triangle inequalities in coherence measures and entanglement concurrence. If a rank-2 state $\ensuremath{\varrho}$ can be expressed as convex combination two pure states, i.e., $\ensuremath{\varrho}={p}_{1}|{\ensuremath{\psi}}_{1}\ensuremath{\rangle}\ensuremath{\langle}{\ensuremath{\psi}}_{1}|+{p}_{2}|{\ensuremath{\psi}}_{2}\ensuremath{\rangle}\ensuremath{\langle}{\ensuremath{\psi}}_{2}|$, inequality established...
We experimentally realize the internal and external entanglement tradeoff, which is a kind of monogamy relation different from that usually discussed. Using source twin photons, we find in photons path-polarization one photon limit each other. In extreme case, when state maximally entangled, must be vanishing, illustrates monogamy. Our results experiment coincide with theoretical predictions therefore provide direct experimental observation relations.Received 9 January 2019Revised 20 August...
Abstract It is well known that one can extract all the information of an unknown quantum channel by means process tomography, such as standard quantum‐process tomography and ancilla‐assisted (AAQPT). Furthermore, it shown entanglement not necessary for AAQPT; there exist separable states are also useful it. Surprisingly, in this work we find entangled some useless. The realignment operation used detection be related to question whether a bipartite state AAQPT. relationship between them...
The monogamy relations of entanglement are highly significant. However, they involve only amounts shared by different subsystems. Results on between and other kinds correlations, particularly classical very scarce. Here we experimentally observe a tradeoff relation internal quantum nonseparability external total correlations in photonic system found that even purely have detrimental effect nonseparability. consider, measured the concurrence, is degrees freedom within same photon, standard...
Based on the quantum coherence theory, we employ [Formula: see text]-norm measure to explore steady-state (SSC) in spin-boson model. In this model, environment is a non-Markovian bosonic bath with Ohmic-like spectral density. More generally, interaction coupling between qubit and linear superposition of pure dephasing damping coupling. Governed by dynamics, some compact expressions SSC have been obtained at both zero temperature high temperature. It shows that hybrid significantly affects...
