A perspective on physical reservoir computing with nanomagnetic devices

2022 · arXiv (Cornell University)

Neural networks have revolutionized the area of artificial intelligence and introduced transformative applications to almost every scientific field and industry. However, this success comes at a great price; the energy requirements for training advanced models …

Spatial correlations in the qubit properties of D-Wave 2000Q measured and simulated qubit networks

2023 · arXiv (Cornell University)

We show strong positive spatial correlations in the qubits of a D-Wave 2000Q quantum annealing chip that are connected to qubits outside their own unit cell. By simulating the dynamics of spin networks, we then …

Reservoir Computing with Magnetic Thin Films

2021 · White Rose Research Online (University of Leeds, The University of Sheffield, University of York)

Advances in artificial intelligence are driven by technologies inspired by the brain, but these technologies are orders of magnitude less powerful and energy efficient than biological systems. Inspired by the nonlinear dynamics of neural networks, …
