- Abstract: It is well known that qubits immersed in a squeezed vacuum environment
exhibit many exotic phenomena, including dissipative entanglement
stabilization. Here, we show that these effects only require interference
between excitation and decay processes, and can be faithfully mimicked without
non-classical light using simple classical temporal modulation. We present
schemes that harnesses this idea to stabilize entanglement between two remote
qubits coupled via a transmission line or waveguide, where either the
qubit-waveguide coupling is modulated, or the qubits are directly driven. We
analyze the resilience of these approaches against various imperfections, and
also characterize the trade-off between the speed and quality of entanglement
stabilization. Our protocols are compatible with state of the art cavity QED
systems.

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.

We demonstrate that this scheme is far more powerful and can also protect a single (or even an ensemble) qubit's energy levels from noise which depends on both time and space.

Temporal, spectral, and sample-to-sample fluctuations in coherence properties of qubits form an outstanding challenge for the development of upscaled fault-tolerant quantum computers.
A ubiquitous source for these fluctuations in superconducting qubits is a set of atomic-scale defects with a two-level structure.
We show that frequency modulation of a qubit or, alternatively, of the two-level defects, leads to averaging of the qubit relaxation rate over a wide interval of frequencies.
