Inferring equilibrium transition rates from nonequilibrium protocols

Kavli Affiliate: David T. Limmer | First 5 Authors: Benjamin Kuznets-Speck, David T Limmer, , , | Summary: We develop a theory for inferring equilibrium transition rates from trajectories driven by a time dependent force using results from stochastic thermodynamics. Applying the Kawasaki relation to approximate the nonequilibrium distribution function in terms of the equilibrium […]

Benchmarking verified logic operations for fault tolerance

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: The promise of quantum computing depends upon the eventual achievement of fault-tolerant quantum error correction, which requires that the total rate of errors falls below some threshold. However, most contemporary methods for benchmarking noisy quantum […]
