Enhancing low-temperature quantum thermometry via sequential measurements
Ning Zhang, Chong Chen, Ping Wang
We propose a sequential measurement protocol for accurate low-temperature estimation. The resulting correlated outputs significantly enhance the low temperature precision compared…

Achieving Heisenberg scaling in low-temperature quantum thermometry
Ning Zhang, Chong Chen
We investigate correlation-enhanced low temperature quantum thermometry. Recent studies have revealed that bath-induced correlations can enhance the low-temperature estimation prec…
