Article Synopsis
- Quantum thermodynamics focuses on understanding how thermodynamic laws apply to thermal machines at the quantum level, where phenomena like coherence and entanglement play significant roles.
- Although progress has been made, it has been challenging to observe these quantum effects in thermal machines.
- The study presents an experimental method to measure quantum corrections caused by quantum friction, using trapped ions and laser techniques, showcasing the ability to identify quantum signatures even amid experimental errors and outside known theoretical limits.
The concept of passivity has been conceived to set bounds on the evolution of microscopic systems initialized in thermal states. We experimentally demonstrate the utility of two frameworks, global passivity and passivity deformation, for the detection of coupling to a hidden environment. We employ a trapped-ion quantum processor, where system qubits undergoing unitary evolution may optionally be coupled to an unobserved environment qubit, resulting in a heat leak.

The lattice is defined by lithographic patterning of a permanent magnetic film. Patterned magnetic-film atom chips enable a large variety of trapping geometries over a wide range of length scales.
