- Abstract summary: We present a mechanism of external coupling of two states via the radiation continuum, which allows for an increase in the lifetime of both single and double excitations.
As an illustrative example, we consider a ring-like ensemble of quantum emitters, demonstrating that one can increase the lifetime of singly and doubly excited states with non-zero orbital momentum by several orders of magnitude.

- Abstract: Arrays of coupled dipole emitters support collective single- and multiphoton
states that can preserve quantum excitations. One of the crucial
characteristics of these states is the lifetime, which is fundamentally limited
due to spontaneous emission. Here, we present a mechanism of external coupling
of two states via the radiation continuum, which allows for an increase in the
lifetime of both single and double excitations. As an illustrative example, we
consider a ring-like ensemble of quantum emitters, demonstrating that upon
slight optimization of the structure geometry, one can increase the lifetime of
singly and doubly excited states with non-zero orbital momentum by several
orders of magnitude.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.
