Developments at the frontier of physical reversibility — where the thermodynamics of information meets the laboratory.

A universal recipe for extracting work without knowing the state
A 2026 result builds a single state-independent quantum process that still extracts work equal to the free energy of an unknown state, near the reversible bound.
PhysicsLandauer's principle tested in the quantum many-body regime
A one-dimensional quantum field simulator made from ultracold Bose gases probes the information–heat bound in a complex, out-of-equilibrium quantum system.
PhysicsFluctuation theorems extended to quantum coherence
A photonic experiment validates a generalized Crooks-type fluctuation theorem in the presence of quantum coherence.
PhysicsInformation engines move beyond proof of concept
Maxwell's-demon engines built from colloids, electrons, quantum dots and qubits now operate close to the Landauer reversible bound.
