“…In the case of continuous variable systems, the entropic criteria proposed in (Walborn et al, 2011) are connected to one of the first criteria mentioned above. In (Reid, 1989) the question is addressed to which extent Alice can infer the value of Bob's position X B or momentum P B by measuring her own canonical variables. The best estimator of X B has as uncertainty the minimal variance…”

“…This is, however, not the only special feature for Gaussian steering. Namely, within the Gaussian regime one can also prove monogamy relations for steering with more than two parties (Adesso and Simon, 2016;Ji et al, 2015a;Lami et al, 2016;Reid, 2013). One should note that the monogamy can break when one is allowed to perform non-Gaussian measurements (Ji et al, 2016).…”

Quantum correlations between two parties are essential for the argument of Einstein, Podolsky, and Rosen in favour of the incompleteness of quantum mechanics. Schrödinger noted that an essential point is the fact that one party can influence the wave function of the other party by performing suitable measurements. He called this phenomenon quantum steering and studied its properties, but only in the last years this kind of quantum correlation attracted significant interest in quantum information theory. In this paper we review the theory of quantum steering. We first present the basic concepts of steering and local hidden state models and their relation to entanglement and Bell nonlocality. Then, we describe the various criteria to characterize steerability and structural results on the phenomenon. A detailed discussion is given on the connections between steering and incompatibility of quantum measurements. Finally, we review applications of steering in quantum information processing and further related topics. 34 J. Quantum teleportation 34 K. Resource theory of steering 35 L.

“…[2] The steering effect shows that one observer can nonlocally influence another observer's state by local measurements. In quantum information processing, it has potential applications such as secure quantum teleportation, [3,4] quantum secret sharing, [5] one-sided device-independent quantum key distribution, [6] Dr. G. channel discrimination, [7,8] entanglement detection [9] etc. So the study of quantum steering has provided new insights to understand quantum theory and consequently attracted increasing interests recently.…”

Activating the Violation of Steering Inequality for Two‐Qubit X States

et al. 2019

The phenomenon of superactivation of quantum steering, that is, the fact that by combining several copies of the unsteerable quantum state one can get a steerable quantum state, has recently attracted much attention. This property is currently only known for isotropic states, and whether there exists an example other than isotropic states is so far an open question. It is of great importance to learn the activation property of non-isotropic states. In this paper, it is shown that the violation of the local uncertainty relations (LUR) steering inequality can be activated for two-qubit X type entangled mixed states. Although the activation phenomenon proven in this paper cannot guarantee the superactivation of steering for two-qubit X states, it does provide clues for this goal. In addition, previous results indicate that two copies are enough for the superactivation of steering, while the price to pay is a high local dimension, and it is unclear whether superactivation is possible with few copies in low-dimensional systems such as two-qubit systems. By providing examples of activation of LUR steering inequality with two copies in a two-qubit system, the work may open a potential way to the solution of this question.

“…On the other hand, Serratia exhibits very low efficiencies of transformation. One of the reasons to explain these low efficiencies of transformation is the ability of Serratia to produce and secrete a potent nuclease [7][8][9]. The nuclease of Serratia was first recognized by Jeffries et al [10] when they described the ability of S. marcescens to degrade DNA as well as RNA.…”

No differences in the efficiency of transformation were observed from both plasmid and chromosomal DNA in Serratia marcescens 2170 and an extracellular nuclease defective isogenic strain. The efficiency of transformation was the same for Escherichia coli 5K and E. coli containing a recombinant plasmid conferring the ability to synthesize a S. marcescens nuclease. From these results we conclude that the extracellular nuclease of S. marcescens 2170 is not the main cause of the low efficiency of transformation observed in this bacterium.
