Speed Limit for a Highly Irreversible Process and Tight Finite-Time Landauer's Bound

Explore the concept of a "tight" finite-time Landauer's bound in this 35-minute lecture by Jae Sung Lee from PCS Institute for Basic Science. Delve into the thermodynamic costs associated with erasing information and the additional energy requirements for finite-time operations. Discover how a general form of the classical speed limit leads to a more accurate bound that captures the divergent behavior of highly irreversible processes. Examine the implications for heat dissipation in high-speed irreversible computation through examples of discrete one-bit and coarse-grained bit systems. Gain insights into the scaling differences between nearly irreversible and highly irreversible processes in information erasure.
