A Quantum Version of the Classical Szilard Engine - ResearchGate
WebNov 2, 2024 · The Szilárd engine is a mechanism (akin to Maxwell's demon) for converting information into energy, which seemingly violates the second law of thermodynamics. Originally a classical thought experiment, it was extended to a quantized treatment by Zurek.
