Thermodynamics of Random Number Generation
C. Aghamohammadi, J. P. Crutchfield
We analyze the thermodynamic costs of the three main approaches to generating random numbers via the recently introduced Information Processing Second Law. Given access to a specif…
The Markov Memory for Generating Rare Events
C. Aghamohammadi, J. P. Crutchfield
We classify the rare events of structured, memoryful stochastic processes and use this to analyze sequential and parallel generators for these events. Given a stochastic process, w…
Extreme Quantum Advantage when Simulating Strongly Coupled Classical Systems
C. Aghamohammadi, J. R. Mahoney, J. P. Crutchfield
Classical stochastic processes can be generated by quantum simulators instead of the more standard classical ones, such as hidden Markov models. One reason for using quantum simula…
Not All Fluctuations are Created Equal: Spontaneous Variations in Thermodynamic Function
James P. Crutchfield, Cina Aghamohammadi
Almost all processes -- highly correlated, weakly correlated, or correlated not at all---exhibit statistical fluctuations. Often physical laws, such as the Second Law of Thermodyna…
The Ambiguity of Simplicity
Cina Aghamohammadi, John R. Mahoney, James P. Crutchfield
A system's apparent simplicity depends on whether it is represented classically or quantally. This is not so surprising, as classical and quantum physics are descriptive frameworks…
