Surpassing the Thermal Cramer-Rao Bound with Collisional Thermometry
Angeline Shu, Stella Seah, Valerio Scarani
In collisional thermometry, a system in contact with the thermal bath is probed by a stream of ancillas. Coherences and collective measurements were shown to improve the Fisher inf…

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…

Violation of all the second laws of thermal operations by inhomogeneous reservoirs
Angeline Shu, Yu Cai, Stella Seah +2
In the resource theory of thermodynamics, the decrease of the free energy based on von Neumann entropy is not a sufficient condition to determine free evolution. Rather, a whole fa…
