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…
Quantum-optimized phase closure for robust interferometric imaging
Zhenning Liu, Emil T. Khabiboulline, Lorcan O. Conlon +7
Closure phase enables imaging with ground-based interferometric arrays by canceling telescope-dependent phase errors due to atmospheric fluctuations. It can be obtained by measurin…
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…
Monolithic Quantum Error Correction in the Presence of Distinguishability
Shubham P. Jain, Eric R. Hudson, Wesley C. Campbell +2
Quantum error-correcting codes require that the environment cannot distinguish relevant error processes acting on different codewords. In practice, residual Zeeman, Stark, or anhar…
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…
Entanglement advantage in sensing power-law spatiotemporal noise correlations
Yu-Xin Wang, Anthony J. Brady, Federico Belliardo +1
Noise sensing underlies many physical applications including tests of non-classicality, thermometry, verification of correlated phases of quantum matter, and characterization of cr…
In-situ Characterization of Light-Matter Coupling in Multimode Circuit-QED Systems
Kellen O'Brien, Won Chan Lee, Alexandra Behne +5
Multimode cavity-QED systems can be leveraged to explore a wide range of physical phenomena; however, a complex multimode environment makes systematic characterization of light-mat…
