Enhancing delocalization and entanglement in asymmetric discrete-time quantum walks
Hao Zhao, Qiyan He, Fengzhi Yang +8
In this paper, we investigate the enhancement of delocalization and coin-position entanglement in asymmetric discrete-time quantum walks (DTQWs). The asymmetry results from asymmet…
Multiparameter quantum estimation with a uniformly accelerated Unruh-DeWitt detector
Shoukang Chang, Yashu Yang, Wei Ye +6
The uniformly accelerated Unruh-DeWitt detector serves as a fundamental model in relativistic quantum metrology. While previous studies have mainly concentrated on single-parameter…
Evidence for rare-region physics in the structural and electronic degrees of freedom of the nickelate LaSrNiO
R. J. Spieker, B. Krohnke, D. Zhai +11
We present a diffuse neutron and x-ray scattering study of structural, spin- and charge-density-wave fluctuations in the electrical insulator LaSrNiO. This lamellar…
Optical kernel machine with programmable nonlinearity
SeungYun Han, Fei Xia, Sylvain Gigan +2
Optical kernel machines offer high throughput and low latency. A nonlinear optical kernel can handle complex nonlinear data, but power consumption is typically high with the conven…
Wavelength-scale noise-resistant on-chip spectrometer
Jianbo Yu, Hsuan Lo, Wenduo Chen +10
Performant on-chip spectrometers are important for advancing sensing technologies, from environmental monitoring to biomedical diagnostics. As device footprints approach the scale…
Angle-Resolved Magneto-Chiral Anisotropy in a Non-Centrosymmetric Atomic Layer Superlattice
Long Cheng, Mingrui Bao, Jingxian Zhang +19
Chirality in solid-state materials has sparked significant interest due to potential applications of topologically-protected chiral states in next-generation information technology…
