The Nonequilibrium Cost of Accurate Information Processing in Quantum Systems

Watch a conference talk from the 18th Theory of Quantum Computation Conference (TQC 2023) exploring fundamental limits on accuracy in quantum information processing systems based on available nonequilibrium resources. Learn about a newly established entropic quantity called "reverse entropy" that helps determine achievable accuracy limits for arbitrary information processing tasks under quantum mechanical laws. Discover how this theoretical framework enables optimal tradeoff analysis between nonequilibrium and accuracy for key information tasks like storage, transmission, cloning and erasure. Understand the implications for designing maximally efficient quantum devices and establishing thermodynamic benchmarks to distinguish genuine quantum systems from classical simulations. The presentation draws from published research in Nature Communications examining these thermodynamic constraints on quantum information processing accuracy.
