Dissipative generation of spin squeezing in the resolved vacuum Rabi splitting limit

Edwin Chaparro, Eric Yilun Song, Diego Barberena +3

Harnessing dissipation in the presence of strong symmetries has recently emerged as a promising route for generating entanglement in atomic clocks. However, previous proposals reli…

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…

Simulation of topological superconductors and their competing orders using photon-mediated interactions

Anjun Chu, Joyce Kwan, Eric Yilun Song +3

Realizing and controlling the unconventional pairing featured by topological superconductors remains a central challenge. We introduce a cavity QED quantum simulator that engineers…

Collective three-body interactions enable a robust quantum speedup

Haoqing Zhang, Anjun Chu, Chengyi Luo +4

We show that collective three-body interactions (3BIs), implementable with atoms loaded inside an optical cavity, offer a significant advantage for preparing complex multiparti…

Engineering One Axis Twisting via a Dissipative Berry Phase Using Strong Symmetries

Jeremy T. Young, Edwin Chaparro, Asier Piñeiro Orioli +2

We show how a driven-dissipative cavity coupled to a collective ensemble of atoms can dynamically generate metrologically useful spin-squeezed states. In contrast to other dissipat…

Realization of three and four-body interactions between momentum states in a cavity through optical dressing

Chengyi Luo, Haoqing Zhang, Chitose Maruko +4

Paradigmatic spin Hamiltonians in condensed matter and quantum sensing typically utilize pair-wise or 2-body interactions between constituents in the material or ensemble. However,…
