- Abstract: Here we report the first observation of simultaneous excitation of two
noninteracting atoms by a pair of time-frequency correlated photons in a
superconducting circuit. The strong coupling regime of this process enables the
synthesis of a three-body interaction Hamiltonian, which allows the generation
of the tripartite Greenberger-Horne-Zeilinger state in a single step with a
fidelity as high as 0.95. We further demonstrate the quantum Zeno effect of
inhibiting the simultaneous two-atom excitation by continuously measuring
whether the first photon is emitted. This work provides a new route in
synthesizing many-body interaction Hamiltonian and coherent control of
entanglement.

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 report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes.
The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments.
The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.
