WebApr 26, 2024 · The viability of nonstoquastic catalyst Hamiltonians to deliver consistent quantum speedups in quantum adiabatic optimization remains an open question. The infinite-range ferromagnetic p -spin model is a rare example exhibiting an exponential advantage for nonstoquastic catalysts over its stoquastic counterpart.

A Divide-and-Conquer Approach to Dicke State Preparation
The Dicke model is a fundamental model of quantum optics, which describes the interaction between light and matter. In the Dicke model, the light component is described as a single quantum mode, while the matter is described as a set of two-level systems. When the coupling between the light and matter … See more The Dicke model is a quantum mechanical model that describes the coupling between a single-mode cavity and $${\displaystyle N}$$ two-level systems, or equivalently $${\displaystyle N}$$ spin-½ degrees of freedom. The … See more The Dicke model of Eq. 1 assumes that the cavity mode and the two-level systems are perfectly isolated from the external environment. In actual experiments, this assumption is not … See more The simplest realization of the Dicke model involves the dipole coupling between two-level atoms in a cavity. In this system, the observation of the superradiant transition is hindered by two possible problems: (1) The bare coupling between atoms and … See more Early studies of the Dicke model considered its equilibrium properties. These works considered the limit of $${\displaystyle N\to \infty }$$ (also known as the … See more Semiclassical limit A phase space for the Dicke model in the symmetric atomic subspace with $${\displaystyle S=N/2}$$ may be constructed by considering the tensor product of the Glauber coherent states q , p ⟩ = D ( q , p ) … See more The Dicke model can be generalized by considering the effects of additional terms in the Hamiltonian of Eq. 1. For example, a recent experiment … See more • Jaynes–Cummings model • Superradiance • Superradiant phase transition See more WebMar 7, 2024 · Abstract By preparing two distant emitters in entangled Dicke states via detection of a single photon, the subsequent spatiotemporal photon emission is investigated. Depending on the parity of the established quantum state, emission patterns for the second scattered photon are observed featuring spatial superradiance as well as subradiance.
