Abstract:

This article presents a cryo-BiCMOS system on chip (SoC) designed for single and two-qubit gate operations for quantum computers (QCs) based on beryllium trapped-ions (TIs). Signal generation from 0.7 to 1.6 GHz is supported, covering all microwave transitions in a ${}^{9}text {Be}^{+}$ QC realization. An integrated 48-kbit waveform memory is implemented for …

Quantum Field Theory Model for Spin-Based Devices Using 2-D van der Waals Materials

Quantum Field Theory Model for Spin-Based Devices Using 2-D van der Waals Materials 150 150
Author(s): Axel I. Saenz Rodriguez, Oksana Ostroverkhova, Pallavi Dhagat

Abstract:

We explore the effects of layered geometries of 2-D quantum spin systems as a method to tune and control material properties for spintronic devices. We analyze the dispersion relation of a 2-D quantum spin system with a shifted bilayer square lattice through the linear spin wave (LSW) approximation of quantum …
