Spin Transfer Theory: A Quantum Computing Perspective

Abstract: Spin Transfer Theory is a promising model for transferring quantum information between spin waves in a spin foam, and using this information to implement quantum computing devices. In this paper, we present a quantum computing perspective on Spin Transfer Theory, and describe how to implement computing devices using quantum circuits. We provide examples of circuits and their corresponding quantum lambdas, which describe the probability distribution of the output states given the input state. Our results demonstrate the potential of Spin Transfer Theory for implementing quantum computing devices.
