Identifying high-energy electronic states of NV− centers in diamond
Applied Physics LettersThe negatively charged nitrogen-vacancy center in diamond is a prototype photoluminescent point defect spin qubit with promising quantum technology applications, enabled by its efficient optical spin polarization and readout. Its low-lying electronic states and optical spin polarization cycle have been well characterized over decades, establishing it ...

Advanced Electronic Materials, EarlyView.A CMOS‐compatible ferroelectric transistor harnesses the interplay between stable gate polarization memory and volatile non‐quasi‐static channel charge dynamics to emulate how biological synapses regulate their own plasticity. This brain‐inspired dual‐memory mechanism, realized in a single device, enables a physical reservoir computer that solves ...

Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations
Advanced Electronic Materials, EarlyView.This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐

Long-range quantum correlations based on quantum coherence in a hybrid system
New Journal of PhysicsWe propose a scheme to realize long-range quantum correlations of two separated ensembles of nitrogen-vacancy (NV) centers via asymmetric driving. Either of the ensembles of NV centers is dynamically driven by a strong applied microwave field, which ...
