Multi‐command wearable magnetic human‐machine interface enabled by low‐noise sensing and time‐series deep learning

open access: yesInfoScience, EarlyView.
This study integrates a wrist‐worn sensing platform based on a low‐noise planar Hall magnetoresistive sensor with time‐series deep learning to enable long‐range, single‐sensor, multi‐command gesture recognition with high accuracy. Further evaluations show reliable generalization across different days, previously unseen users, wearing‐position ...

Van der Waals ferroelectric semiconductor tunnel junction with ultra‐low switching voltage

open access: yesInfoMat, EarlyView.
Ferroelectric tunnel junctions are promising building blocks for energy‐efficient memory and brain‐inspired computing, but their practical use is limited by the relatively high voltages required for operation. Here, we develop an all‐two‐dimensional ferroelectric tunnel junction based on AgBiP2Se6 that enables reliable memory operation below 0.2 V and ...

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

open access: yesLaser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

A Scalable Platform for Massively Parallel Superconducting Single‐Photon Detection

open access: yesLaser &Photonics Reviews, EarlyView.
One hundred independent superconducting nanowire detectors, each with efficiency up to 80.1–98.3%, are integrated into a single compact system operating below 2.1 K. This parallel architecture supports fully connected multi‐user quantum entanglement distribution, while its scalability opens new avenues in optical quantum computing, QKD networks ...

Programmable Temporal Dynamics in a Laser Neuron for High‐Speed Photonic Reservoir Computing

open access: yesLaser &Photonics Reviews, EarlyView.
Memory and nonlinearity play crucial roles in reservoir computing (RC). An adaptive photonic RC system is demonstrated based on a high‐speed laser graded neuron, whose dynamics, encompassing memory and nonlinearity, can be flexibly programmed through a straightforward bias‐tuning approach.
