Thermodynamic computing via autonomous quantum thermal machines

P Lipka-Bartosik, M Perarnau-Llobet, N Brunner - Science Advances, 2024 - science.org
We develop a physics-based model for classical computation based on autonomous
quantum thermal machines. These machines consist of few interacting quantum bits (qubits) …

Thermodynamic Natural Gradient Descent

K Donatella, S Duffield, M Aifer, D Melanson… - arXiv preprint arXiv …, 2024 - arxiv.org
Second-order training methods have better convergence properties than gradient descent
but are rarely used in practice for large-scale training due to their computational overhead …

Error Mitigation for Thermodynamic Computing

M Aifer, D Melanson, K Donatella, G Crooks… - arXiv preprint arXiv …, 2024 - arxiv.org
While physics-based computing can offer speed and energy efficiency compared to digital
computing, it also is subject to errors that must be mitigated. For example, many error …
