Landauer’s Principle Workshop – 11 July 2022

On Monday 11 July 2022 there was a free one-day workshop at the University of Bristol on the topic of Landauer’s Principle, funded in part by the FraMEPhys project and the Leverhulme Trust.

When? 11th July 2022, 9.30-5.00

Where? The Berry Lecture Theatre, 3.21, Physics Department, University of Bristol. 

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.
