Time Symmetries of Memory Determine Thermodynamic Efficiency
Alexander B. Boyd, Paul M. Riechers, Gregory W. Wimsatt +2
While Landauer's Principle sets a lower bound for the work required for a computation, that work is recoverable for efficient computations. However, practical physical computers, s…
Refining Landauer's Stack: Balancing Error and Dissipation When Erasing Information
Gregory W. Wimsatt, Alexander B. Boyd, Paul M. Riechers +1
Nonequilibrium information thermodynamics determines the minimum energy dissipation to reliably erase memory under time-symmetric control protocols. We demonstrate that its bounds…
Non-Markovian Momentum Computing: Universal and Efficient
Kyle J. Ray, Gregory W. Wimsatt, Alexander B. Boyd +1
All computation is physically embedded. Reflecting this, a growing body of results embraces rate equations as the underlying mechanics of thermodynamic computation and biological i…
Nonequilibrium thermodynamics of erasure with superconducting flux logic
Olli-Pentti Saira, Matthew H. Matheny, Raj Katti +5
We implement a thermal-fluctuation driven logical bit reset on a superconducting flux logic cell. We show that the logical state of the system can be continuously monitored with on…
Balancing Error and Dissipation in Computing
P. M. Riechers, A. B. Boyd, G. W. Wimsatt +1
Modern digital electronics support remarkably reliable computing, especially given the challenge of controlling nanoscale logical components that interact in fluctuating environmen…
