Quantum reservoir computing with classical and nonclassical states in an integrated optical circuit
S. Świerczewski, W. Verstraelen, P. Deuar +3
Quantum reservoir computing (QRC) is a hardware-implementation-friendly quantum neural network scheme with minimal physical system requirements and a proven advantage over classica…
Off-resonant preservation and generation of imaginarity in distributed scenarios
Si-Min Wang, Ming-Liang Hu, Heng Fan
We study the nonlocal advantage of quantum imaginarity (NAQI) and distillable imaginarity of assistance (DIA), which treat imaginarity as a resource in distributed scenarios. For t…
Emergence of long-range entanglement and odd-even effect in periodic generalized quantum cluster models
Zhen-Yu Zheng, Shu Chen
We investigate the entanglement properties in a generalized quantum cluster model under periodic boundary condition. By evaluating the quantum conditional mutual information entrop…
A Qudit-native Framework for Discrete Time Crystals
Wei-Guo Ma, Heng Fan, Shi-Xin Zhang
We introduce a qudit-native framework for engineering rich and robust discrete time crystals (DTCs) by leveraging their internal multilevel structure. Unlike in qubit systems, qudi…
Kostant relation in filtered randomized benchmarking for passive bosonic devices
David Amaro-Alcalá
We aim to reduce the cost of the current bosonic randomized benchmarking proposal. To do this, we introduce two filter functions: one uses immanants, the other uses characters of t…
Generalised fractional Rabi problem
Alexander Lopez, Sébastien Fumeron, Malte Henkel +2
Fractional quantum dynamics provides a natural framework to capture nonlocal temporal behavior and memory effects in quantum systems. In this work, we analyze the physical conseque…
