Recurrent neural networks (RNNs), particularly long short-term memory (LSTM), have gained much attention in automatic speech recognition (ASR). Although some successful stories been reported, training RNNs remains highly challenging, especially with limited data. Recent research found that a well-trained model can be used as teacher to train other child models, by using the predictions generated supervision. This knowledge transfer learning has employed simple nets complex one, so final...

Uncertainty principle is a striking and fundamental feature in quantum mechanics distinguishing from classical mechanics. It offers an important lower bound to predict outcomes of two arbitrary incompatible observables measured on particle. In information theory, this uncertainty popularly formulized terms entropy. Here, we present improvement tripartite quantum-memory-assisted entropic relation. The uncertainty's derived by considering mutual Holevo quantity. shows that the method will be...

Two protocols of quantum direct communication with authentication [Phys. Rev. A 73, 042305 (2006)] were recently proposed by Lee, Lim, and Yang. In this paper we will show that in the two authenticator Trent should be prevented from knowing secret message. The first protocol can eavesdropped on using intercept-measure-resend attack, while second a simple single-qubit measurement. To fix these leaks, revise original versions Pauli $Z$ operation ${\ensuremath{\sigma}}_{z}$ instead bit-flip...

The uncertainty relation is a fundamental limit in quantum mechanics and of great importance to information processing as it relates precision measurement. Due interactions with the surrounding environment, system will unavoidably suffer from decoherence. Here, we investigate dynamic behaviors entropic an atom-cavity interacting under bosonic reservoir during crossover between Markovian non-Markovian regimes. Specifically, explore behavior for pair incompatible observables reservoir-induced...

Besides, from to experiences a "sudden death" with increasing decoherence strength. However, shortly after that, recovery increase of strength in...

Recently, an entropic uncertainty relation for multiple measurements was proposed by Liu et al. [Phys. Rev. A 91, 042133 (2015)]. However, the lower bound of is not always tight with respect to different measurements. Herein, we improve measurements, referred as a simply constructed (SCB). We verify that SCB tighter than al.'s result arbitrary mutually unbiased basis which might play fundamental and crucial role in practical quantum information processing. Moreover, optimize considering...

Abstract We explore the tripartite entropic uncertainty and genuine quantumness of Dirac fields in background Garfinkle–Horowitz–Strominger (GHS) dilation space-time. It is interesting to note that Hawking radiation leads decay quantum nonlocality physically accessible region while preserving its total coherence. More importantly, it demonstrates an intrinsic trade-off relationship between coherences inaccessible regions. Moreover, we examine effect on entropy-based measured find stronger...
