Machine Learning for Maximizing the Memristivity of Single and Coupled Quantum Memristors

open access: yesAdvanced Quantum Technologies, EarlyView.
Machine learning (ML) methods are proposed to characterize the memristive properties of single and coupled quantum memristors. It is shown that maximizing the memristivity leads to large values in the degree of entanglement of two quantum memristors, unveiling the close relationship between quantum correlations and memory.

Hybrid Encoder for Discrete and Continuous Variable QKD

open access: yesAdvanced Quantum Technologies, EarlyView.
This work demonstrates a hybrid QKD encoder that bridges the advantages of discrete and continuous variables. Utilizing a self‐compensating iPOGNAC design, the encoder is compatible with space‐based and terrestrial quantum networks. The approach simplifies system complexity, improves stability, and ensures cost‐effective integration, paving the way for

Non‐Markovian Dynamics in Fiber Delay‐Line Buffers

open access: yesAdvanced Quantum Technologies, EarlyView.
A qubit‐fiber birefringence‐reservoir model is proposed to explore the non‐Markovian dynamics of the fiber‐based buffered photon and its paired photon. The non‐Markovian probability function is obtained by performing full quantum state tomography. The probability function fits well with experimental data and physical values.

Reproducing the Effects of Quantum Deformation in the Undeformed Jaynes‐Cummings Model

open access: yesAdvanced Quantum Technologies, EarlyView.
The inverse problem approach, where atomic probabilities are modulated according to a time‐dependent coupling, is studied for the Jaynes‐Cummings (JC) model. In particular, emphasis is placed on how to reproduce the effects of quantum deformation in a non‐deformed JC model.
