Nanoscale magnetic devices for Non-volatile Memory, Hardware AI and Quantum Computing
ECE Distinguished Seminar - Northwestern University
This talk will start with a brief overview of some of the key challenges in classical and quantum computing. Following
this, the potential use of nanoscale magnetic devices to solve such problems, as well as the rich and interesting physics
in nanoscale magnetism that can be leveraged for various device applications will be discussed. For example,
competing energies in nanoscale structures can lead to exotic spin states that we have shown to have potential for
extremely energy efficient non-volatile computer memory and AI hardware that are amenable to implement in
edge/IoT devices. On the other hand, we have proposed the use of such nanomagnetic devices to address and control
spin qubits. By tuning the frequency of the nanomagnet’s electric field drive to the Larmor frequency of the spins
confined to a nanoscale volume, single-qubit quantum gates with fidelities approaching those of fault-tolerant
quantum computing can be implemented.
Prof. Jayasimha Atulasimha is an Engineering Foundation Professor of Mechanical and Nuclear Engineering with a
courtesy/affiliate appointment in Electrical and Computer Engineering and Physics at the Virginia Commonwealth University.
His current research interests include nanomagnetism, spintronics, non-volatile memory, hardware AI and quantum computing
with spins. He is a fellow of the ASME, an IEEE Senior Member and past chair for the Technical Committee on Spintronics, IEEE
Nanotechnology Council. He also serves as the Associate Director for the Institute for Sustainable Energy and Environment
(ISEE) at VCU.
