Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

All-optical NOT logic gate is theoretically described using the concept of polarization-conversion in ring resonator. Conversion of polarization states occurs at very high speed of 0.2 ps and high ...

This paper presents an analytical model for quantum-confinement effects in short-channel gate-all-around (GAA) MOSFETs under the subthreshold region. Our analytical model accurately predicts the ...
