- Abstract: We propose that the squeezed light accompanied by hyperradiance is induced by
quantum interference in a linear system consisting of a high quality optical
cavity and two coherently driven two-level qubits. When two qubits are placed
at the crest and trough of the standing wave in the cavity respectively (i.e.,
they have the opposite coupling coefficient to the cavity), we show that
squeezed light is generated in the hyperradiance regime under the conditions of
strong coupling and weak driving. Simultaneously, the Klyshko's criterion
alternates up and down at unity when the photon number is even or odd.
Moreover, the orthogonal angles of the squeezed light can be controlled by
adjusting the frequency detuning pressure between the driving field and the
qubits. It can be implemented in a variety of quantum systems, including but
not limited to two-level systems such as atoms, quantum dots in single-mode
cavities.

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.
