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…
Deciding the Attainability of the Multiparameter Quantum Fisher Information is NP-Hard
Lorcan O. Conlon, Laura Shou, V Vijendran +7
The quantum Fisher information (QFI) sets a fundamental bound on the attainable precision when estimating multiple parameters simultaneously. Incompatibility among the individually…
Quantum advantage in learning single mode bosonic channels
Angela Anna Baiju, Aritra Das, Özlem Erkılıç +7
Quantum resources can dramatically reduce the data required to learn physical systems, with exponential improvements in sample complexity demonstrated in several quantum learning t…
Years of Quantum Uncertainty: From Origins to Modern Insights
Lorcan O. Conlon, Biveen Shajilal, Jie Zhao +6
Heisenberg's uncertainty principle is a cornerstone of quantum mechanics, marking a decisive departure from classical physics. Conceived almost a century ago through a thought expe…
Beating three-parameter precision trade-offs with entangling collective measurements
Simon K. Yung, Wen-Zhe Yan, Lan-Tian Feng +10
Quantum-mechanical incompatibility, which precludes the simultaneous precise measurement of non-commuting observables, imposes fundamental limits on the rate at which classical inf…
In-Line Fiber-Integrated Photon-Pair Generation from van der Waals Crystals
Mayank Joshi, Tanumoy Pramanik, Mengting Jiang +9
Miniaturized quantum light sources that operate directly in optical fibers are an attractive platform for optical quantum technologies. However, most miniaturized spontaneous param…
