Quantum Sensing
Quantum Sensing
Quantum sensing is the art of efficiently interrogating a natural system to know its properties. They promise to revolutionise healthcare through measuring ultrasmall electromagnetic fields inside our body, improve mineral prospecting through measuring small shifts in gravity, as well as a host of other applications.
My own research on quantum sensing has been about developing theoretical techniques. For thermometry, we introduced weak-measurement based and quantum switch augmented quantum sensing protocols. For magnetometry, we settled a key debate regarding the source of quantum advantage by introducing topological quantum sensors and demonstrated how building a modular probe is more efficient than one giant probe. We also provided theoretical protocols for better global and multiparameter sensing. On the pedagogical side, I have contributed to two major reviews on many-body quantum metrology as well as global quantum metrology.
I am currently actively looking for collaborations, so please feel free to knock me up.
