“…In recent years, people are very interesting in the study of relativistic quantum information processing, because realistic quantum regimes are essentially non‐inertial. From the aspect of relativistic frameworks, Unruh effect or/and Hawking radiation will lead to the loss of quantum information, such as quantum entanglement, [ 36–39 ] quantum steering, [ 40–42 ] and quantum coherence. [ 43–49 ] In the degradation of quantum information, fermionic and bosonic fields have distinctively different behaviors [ 38,50 ] due to the different statistics that the particles submitted.…”

The distribution and evolution of quantum coherence for multi‐qubit W and GHz states of Dirac fields in the non‐inertial frames and under the action of local environments is studied. It is found that the N‐qubit W state has all orders of coherence (from bipartite to N‐partite subsystems), and the coherence of the whole system is equal to the sum of all the bipartite coherences in the whole time evolution. However, the evolved N‐qubit GHz state has its coherence belonged only to the whole system and no coherence resides in any subsystems. Further, it is found that the expressions of coherence for both W and GHz states are covariant with respect to the transformation of decaying rates.

“…As quantum systems interact with several surrounding environments, it was essential to indicate the effect of these surroundings on the steering correlation [19,20]. For instance, the efficacy of relativistic motion, the noisy channel, finite temperature, non-Markovian environment, and a cavity optomechanical system on the steering have been discussed [12,[21][22][23][24]. Mathematically, the degree of steerability and steering inequality have been diagnosed via different relations such as, Heisenberg uncertainty principle [25], steering witnesses [26], the standard geometric Bell inequalities [27,28], and the maximal violation of the Clauser-Horne-Shimony-Holt inequality [29,30].…”

The bidirectional steerability between different-size subsystems is discussed for a single parameter accelerated qubit-qutrit system. The decoherence due to the mixing and acceleration parameters is investigated, where for the total system and the qutrit, it increases as the mixing parameter increases, while it decreases for the qubit. The non-classical correlations are quantified by using the local quantum uncertainty, where it increases at large values of the acceleration parameter. The possibility that each subsystem steers each other is studied, where the behavior of the steering inequality predicts that the qubit has a large ability to steer the qutrit. The degree of steerability decays gradually when the qubit is accelerated. However, it decays suddenly when the qutrit or both subsystems are accelerated. The degree of steerability is shown for the qutrit/qubit vanishes at small/large values of the acceleration. The difference between the degrees of steerability depends on the initial state settings and the size of the accelerated subsystem.

“…Quantum steering is a special quantum phenomenon, which allows an observer by measuring his subsystem to control the remote subsystem owned by another observer. Since Wiseman et al in 2007 firstly gave the resource definition of quantum steering via the local hidden state (LHS) model [3], quantum steering has attracted renewed interest [4][5][6][7][8][9][10][11][12][13]. Various inequalities for detecting quantum steering of quantum states have been proposed [14][15][16][17][18][19].…”

Using two different types of quantification for quantum steering, we study the influence of Hawking radiation on quantum steering for fermionic fields in Schwarzschild spacetime. The degradation for the steering between physically accessible observers and the generation for the steering between physically accessible and inaccessible observers induced by Hawking radiation are studied. We also reveal the difference between the two types of quantification for steering, and find some monogamy relations between steering and entanglement. Furthermore, we show the different properties between fermionic steering and bosonic steering in Schwarzschild spacetime.
