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…
Lieb-Mattis states for robust entangled differential phase sensing
Raphael Kaubruegger, Diego Fallas Padilla, Athreya Shankar +10
We explore a two-node, entanglement-enhanced sensor network for differential phase sensing that exploits decoherence-free subspaces to suppress common-mode noise, a primary limitat…
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…
Correlated Noise Estimation with Quantum Sensor Networks
Anthony J. Brady, Yu-Xin Wang, Victor V. Albert +2
We address the metrological problem of estimating collective stochastic properties imprinted on a network of quantum sensors. Canonical examples include center-of-mass quadrature f…
Landscape of scattering universality with general dispersion relations
Yidan Wang, Xuesen Na, Michael J. Gullans +2
Universality in physics describes how disparate systems can exhibit identical low-energy behavior. Here, we reveal a rich landscape of new universal scattering phenomena governed b…
