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…
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,…
Collectively enhanced Ramsey readout by cavity sub- to superradiant transition
Eliot Bohr, Sofus L. Kristensen, Christoph Hotter +6
When an inverted ensemble of atoms is tightly packed on the scale of its emission wavelength or when the atoms are collectively strongly coupled to a single cavity mode, their dipo…
Displacement operators: the classical face of their quantum phase
Amar C. Vutha, Eliot A. Bohr, Anthony Ransford +2
In quantum mechanics, the operator representing the displacement of a system in position or momentum is always accompanied by a path-dependent phase factor. In particular, two non-…
