Landauer’s principle claims that there is a thermodynamic cost to resetting, or erasing, information. This forges a connection between logical and thermodynamic irreversibility that some say gives rise to a new field – ‘the thermodynamics of computation’ – and that others denounce as heresy. This workshop brings together physicists and philosophers to see what new light can be shed on Landauer’s principle.
