TL;DR: Quantum supremacy is demonstrated using a programmable superconducting processor known as Sycamore, taking approximately 200 seconds to sample one instance of a quantum circuit a million times, which would take a state-of-the-art supercomputer around ten thousand years to compute.
Journal ArticleDOI
Strongly interacting polaritons in coupled arrays of cavities
TL;DR: In this article, a system of polaritons held in an array of resonant optical cavities, which could be realized using photonic crystals or toroidal microresonators, was shown to form a strongly interacting many-body system showing quantum phase transitions, where individual particles can be controlled and measured.
Journal ArticleDOI
Quantum many-body phenomena in coupled cavity arrays
TL;DR: In this paper, the authors survey recent theoretical studies concerning the use of cavity quantum electrodynamics to create quantum many-body systems, including the Bose-Hubbard and anisotropic Heisenberg models.
Journal ArticleDOI
Photon blockade in the ultrastrong coupling regime.
TL;DR: By expressing the electric-field operator in the cavity-emitter dressed basis, this work is able to propose correlation functions that are valid for arbitrary degrees of light-matter interaction and shows that the standard photon blockade scenario is significantly modified for ultrastrong coupling.
