Maxwell's lesser demon: a quantum engine driven by pointer measurements
Stella Seah, Stefan Nimmrichter, Valerio Scarani
We discuss a self-contained spin-boson model for a measurement-driven engine, in which a demon generates work from thermal excitations of a quantum spin via measurement and feedbac…

Collisional quantum thermometry
Stella Seah, Stefan Nimmrichter, Daniel Grimmer +3
We introduce a general framework for thermometry based on collisional models, where ancillas probe the temperature of the environment through an intermediary system. This allows fo…

Almost thermal operations: inhomogeneous reservoirs
Angeline Shu, Yu Cai, Stella Seah +2
The resource theory of thermal operations explains the state transformations that are possible in a very specific thermodynamic setting: there is only one thermal bath, auxiliary s…
