Moving quantum sensors
Evan Zhang, Erfan Abbasgholinejad, Yu-Xin Wang +6
We investigate whether controlled motion of a quantum sensor offers a metrological advantage in a field-detection task. We consider a localized field of known strength occupyin…
Bosonic unstructured search: quantum enhancement without entanglement
Yu-Xin Wang, Erfan Abbasgholinejad, Supratik Sarkar +4
We consider unstructured search using multimode bosonic quantum systems under energy constraints. The task is to locate an unknown marked mode among possibilities using arbitra…
Super-Exponential Advantage of Squeezed Light in Phase Estimation under Discrete Phase Randomisation
Lorcan O. Conlon, V Vijendran, Aritra Das +7
A paradigmatic task in quantum metrology is that of phase estimation. For this task it is commonly believed, under reasonable assumptions about prior information, that a quadratic…
Error-corrected function estimation advantage in multiparameter Hamiltonians
Erfan Abbasgholinejad, Lorcán O. Conlon, Sean R. Muleady +4
We establish the ultimate precision limits for estimating a function of multiple Hamiltonian parameters in the presence of Markovian noise. By reducing multiparameter function esti…
Fault-Tolerant Heisenberg-Limited Quantum Sensing
Lorcan O. Conlon, Yu-Xin Wang, Erfan Abbasgholinejad +3
Quantum sensors hold great promise for achieving better sensitivity in the measurement of physical quantities compared to their classical counterparts. However, the conditions unde…
Multiparameter function estimation for general Hamiltonians
Erfan Abbasgholinejad, Sean R. Muleady, Jacob Bringewatt +2
Estimation of physical parameters encoded in a Hamiltonian is a central task in quantum sensing and learning. While the ultimate precision limit for estimating a single parameter c…
