5. The three-way trade-off
of information
1. Maxwell’s and Shilard’s demons
process information to convert heat
into work
2. Information engines turn information
into heat or dump entropy into an
empty information register
3. Conventional engines use heat to
work → destroys information
Information
Work Heat

6. Programmable Mechanical
Maxwell’s Demon
by Zhiyue Lu and Christopher Jarzynski
https://www.mdpi.com/1099-4300/21/1/65
2014: converts random thermal motion
into directional rotation that could be used
to raise a weight, but in so doing the output
state of the blades is now a random
mixture of 1s and 0s.
thus converts heat into work and writes
information into a register
https://youtu.be/LkYljJ__-Cs
2019: can be programmed to recognize a
chosen reference e.g: π
If the bits in the memory register match those
of the reference sequence, then the device
extracts heat from the thermal reservoir and
converts it into work to lift a small mass.
