Revival of quantum steering in correlated noisy channels

Abstract

Multipartite quantum steering has crucial applications in the field of asymmetric secure quantum networks. In the actual quantum communication transmission process, the inevitable loss and noise in the channels will lead to reduction or even disappearance of quantum steering, which is extremely unfavorable to the transmission of information, so it has important practical significance for research of the revival of quantum steering. We theoretically studied the influence of noise on steering and investigated the revival of quantum steering by correlated noisy channels. The results show that excessive noise can cause sudden death of steering, whereas the disappeared steering can be revived by introducing correlated noise. Simultaneously, we also confirmed that the steerability and direction of steering can be manipulated by changing the transmissivity of the revived beam splitter. Our work provides a feasible reference for secure quantum communication in real noisy environment.

Revival and distribution of Einstein–Podolsky–Rosen steering of a four-mode cluster state in noisy channels

Shuqin Zhai, Nana Zhang, Xiaolan Kang +1 more

Einstein–Podolsky–Rosen steering is an important resource for constructing secure quantum communication networks. The quantum states carry information transmitted among the spatially separated nodes through the quantum channels, and the steerability of quantum states will reduce or even completely disappear due to the noise in the channels. We theoretically studied the revived steering properties of the quadripartite quantum state. The steering properties versus transmission efficiency and noise amplitude were investigated. Our studies show that when the noise in the channels reaches a certain value, it will lead to the sudden death of steering, and the steerability can be revived over a large range of values by establishing correlated noisy channels. Different types of monogamy relationships are verified in our scheme. These results provide a theoretical foundation for the construction of secure quantum networks.

Sudden death and revival of Gaussian Einstein–Podolsky–Rosen steering in noisy channels

Xiaowei Deng, Yang Liu, Meihong Wang +2 more

Abstract Einstein–Podolsky–Rosen (EPR) steering is a useful resource for secure quantum information tasks. It is crucial to investigate the effect of inevitable loss and noise in quantum channels on EPR steering. We analyze and experimentally demonstrate the influence of purity of quantum states and excess noise on Gaussian EPR steering by distributing a two-mode squeezed state through lossy and noisy channels, respectively. We show that the impurity of state never leads to sudden death of Gaussian EPR steering, but the noise in quantum channel can. Then we revive the disappeared Gaussian EPR steering by establishing a correlated noisy channel. Different from entanglement, the sudden death and revival of Gaussian EPR steering are directional. Our result confirms that EPR steering criteria proposed by Reid and I. Kogias et al. are equivalent in our case. The presented results pave way for asymmetric quantum information processing exploiting Gaussian EPR steering in noisy environment.

Distribution and revival of tripartite Einstein–Podolsky–Rosen steering in all-optical correlated noise channel

Shuqin Zhai, Xinyan Shi, Kui Liu

Abstract Quantum steering, also know as Einstein–Podolsky–Rosen steering, is a key resource in quantum information. It has significant application value for constructing secure quantum communication networks due to its unique asymmetric property. However, quantum steering is susceptible to decoherence. Decoherence occurs due to the interaction between a quantum system and its environment, and eventually leads to the reduction or even disappearance of steering. In this paper, we propose an all-optical correlated noise channel (ACNC) scheme based on four-wave mixing (FWM) processes, investigate the impact of noise in the channel and FWM gains on quantum steering characteristics as well as the capability of the ACNC to restore quantum steering. This scheme is achieved through optical nonlinear processes and avoids the electro-optic conversions and significantly expands the operational bandwidth. The research results show that the ACNC can effectively restore the damaged quantum steering. The range of one-way steering and genuine tripartite steering can be flexibly controlled by adjusting parameters. Moreover, the Gaussian steered monogamous relationships have also been verified. Our scheme provides new theoretical reference for constructing all-optical secure quantum networks.

Observation of Non-Markovian Evolution of Tripartite Quantum Steering

Yan Wang, Shao-qi Lin, Rui-qi Shen +6 more

The memory effects in open quantum systems can induce information backflow and revive quantum correlations, thereby providing a powerful way to protect and recover useful quantum resources in realistic noisy environments. However, such dynamics remains experimentally unexplored in multipartite quantum steering. Here we observe different non-Markovian evolution of tripartite quantum steering using Greenberger-Horne-Zeilinger-type mixed states, covering both death and revival processes. In particular, we experimentally demonstrate the more intricate asymmetric steering structure of tripartite quantum steering through different bipartitions, which do not arise in bipartite systems. Our results provide foundational insights into the hierarchical and directional structures in multipartite quantum steering, and highlight its potential as a useful resource for asymmetric quantum information processing.

Disappearance and revival of squeezing in quantum communication with squeezed state over a noisy channel

Xiaowei Deng, Shuhong Hao, Caixing Tian +3 more

Squeezed state can increase the signal-to-noise ratio in quantum communication and quantum measurement. However, losses and noises existing in real communication channels will reduce or even totally destroy the squeezing. The phenomenon of disappearance of the squeezing will result in the failure of quantum communication. In this letter, we present the experimental demonstrations on the disappearance and revival of the squeezing in quantum communication with squeezed state. The experimental results show that the squeezed light is robust (squeezing never disappears) in a pure lossy but noiseless channel. While in a noisy channel, the excess noise will lead to the disappearance of the squeezing, and the squeezing can be revived by the use of a correlated noisy channel (non-Markovian environment). The channel capacity of quantum communication is increased after the squeezing is revived. The presented results provide useful technical references for quantum communication with squeezed light.

Avoiding disentanglement of multipartite entangled optical beams with a correlated noisy channel

Xiaowei Deng, Caixing Tian, Xiaolong Su +1 more

A quantum communication network can be constructed by distributing a multipartite entangled state to space-separated nodes. Entangled optical beams with highest flying speed and measurable brightness can be used as carriers to convey information in quantum communication networks. Losses and noises existing in real communication channels will reduce or even totally destroy entanglement. The phenomenon of disentanglement will result in the complete failure of quantum communication. Here, we present the experimental demonstrations on the disentanglement and the entanglement revival of tripartite entangled optical beams used in a quantum network. We experimentally demonstrate that symmetric tripartite entangled optical beams are robust in pure lossy but noiseless channels. In a noisy channel, the excess noise will lead to the disentanglement and the destroyed entanglement can be revived by the use of a correlated noisy channel (non-Markovian environment). The presented results provide useful technical references for establishing quantum networks.
